In today’s world, electronics are everywhere. From smartphones to medical devices, they power modern life. But these devices face a hidden challenge: electromagnetic interference (EMI). This interference can disrupt their performance or even cause them to fail. That’s where EMI/EMC filters come in. These filters ensure electronics work reliably by blocking unwanted signals.As technology advances, the need for these filters grows. For example, the EMI/EMC filters market is expected to nearly double, from $1.5 billion to $2.8 billion by 2032. The rise of 5G, with higher frequencies and faster data rates, brings more interference. Smaller devices also demand compact filters with high performance. Without these filters, modern electronics would struggle to keep up with the demands of 2025.Understanding EMI and EMCWhat is electromagnetic interference (EMI)?Electromagnetic interference, or EMI, occurs when unwanted electromagnetic signals disrupt the normal operation of electronic devices. These signals can come from various sources, such as power lines, motors, or even other electronic devices. For example, when you hear static on your radio while using a nearby hairdryer, that’s EMI in action.Recent studies indicate that the high-speed switching of SiC MOSFETs can lead to significant EMI issues due to the interaction with parasitic components in the circuit. The primary sources of EMI are linked to rapid changes in voltage and current (dv/dt and di/dt), which generate high-frequency noise. Additionally, the use of passive filters with high insertion loss is recommended to mitigate conducted EMI noise in motor drive control systems.EMI can be classified into two types: conducted and radiated. Conducted EMI travels through wires or cables, while radiated EMI spreads through the air. Both types can interfere with sensitive electronics, making EMI/EMC Filters essential for maintaining device performance.What is electromagnetic compatibility (EMC)?Electromagnetic compatibility, or EMC, ensures that electronic devices can operate without causing or experiencing interference. In simple terms, EMC means your devices can work together without disrupting each other.

They block unwanted noise while allowing desired signals to pass through. This process enhances the performance of your devices and ensures they function reliably.Here are some common configurations used in EMI/EMC filters:Feed-through capacitors: The simplest form, ideal for basic noise suppression.L-circuit filters: Combine inductors and capacitors for effective filtering.PI-circuit filters: Divert noise at high-impedance nodes.T-circuit filters: Suppress noise at low-impedance nodes.Filter TypeFunctionalityLow-Pass FiltersStop high-frequency noise from entering or leaving a system.Feed-Through CapacitorSimplest form of EMI filter, consisting of a single component.L-Circuit FilterA basic configuration that uses inductors and capacitors to filter noise.PI-Circuit FilterCombines capacitors and inductors to create a low-impedance path for noise at high-Z nodes.T-Circuit FilterDesigned for low-Z nodes, using inductors to suppress noise effectively.By placing these filters between circuits, you can effectively suppress conducted and radiated interference. This suppression minimizes disruptions and ensures your devices perform as intended.The role of EMI/EMC filters in ensuring device reliabilityEMI/EMC filters play a critical role in protecting sensitive electronics from electromagnetic interference. High levels of electrical noise can cause data loss, malfunctions, or even complete device failure. These filters act as shields, limiting the penetration of noise signals and safeguarding your devices.For instance, in medical equipment, EMI filters prevent interference that could disrupt life-saving devices like pacemakers. In industrial machinery, they ensure smooth operation by blocking noise from motors and power lines. The global EMI filters market, valued at $274.5 million in 2022, highlights their importance. With a projected growth rate of 4.1% annually, the market is expected to reach $392.1 million by 2031.Note: Investing in high-quality EMI/EMC filters not only boosts device reliability but also reduces maintenance costs and downtime.Key Components of EMI/EMC FiltersCapacitors: Their role in filtering high-frequency noiseCapacitors are essential in EMI/EMC Filters because they filter out high-frequency noise from electronic circuits. They work by creating a low-impedance path for unwanted signals, diverting them away from sensitive components. You’ll often find capacitors in power lines, where they decouple common-mode noise generated by switching power supplies (SMPS).Different types of capacitors serve specific purposes:X-capacitors: These inhibit differential mode interference, which occurs between two conductors.Y-capacitors: These filter common-mode noise, which flows between a conductor and ground.Decoupling capacitors also stabilize voltage levels by acting as local energy reservoirs. They provide current during transient conditions, ensuring a steady DC supply. This minimizes crosstalk in digital circuits, keeping your devices running smoothly.Inductors: How they block unwanted signalsInductors are another critical component in EMI/EMC Filters. They block unwanted signals by resisting changes in current. When high-frequency noise tries to pass through, the inductor creates a magnetic field that opposes the current flow, effectively filtering out the interference.The effectiveness of an inductor is often measured by its insertion loss. This parameter shows how much noise the inductor removes from the circuit. Engineers also use S-parameter measurements, like the transmission coefficient (S21), to evaluate how well the inductor blocks unwanted signals. These measurements ensure the filter performs as expected in real-world conditions.Resistors: Their contribution to damping and stabilityResistors play a supporting role in EMI/EMC Filters by providing damping and stability. They help control the oscillations that can occur when capacitors and inductors interact. By dissipating excess energy as heat, resistors prevent voltage spikes and ensure the filter operates reliably.In addition, resistors improve the overall performance of the filter by reducing the risk of resonance. This makes them indispensable in maintaining the stability of electronic circuits, especially in high-frequency applications.Tip: When designing EMI/EMC Filters, consider the specific noise profile of your application. This helps you choose the right combination of capacitors, inductors, and resistors for optimal performance.Ferrite beads: Reducing high-frequency noise in circuits.Ferrite beads are small but powerful components that help reduce high-frequency noise in electronic circuits. You’ll often find them in EMI/EMC Filters, where they act as barriers to unwanted signals. These beads are made from ferrite, a magnetic material that absorbs and dissipates high-frequency noise as heat.When you place a ferrite bead on a wire or cable, it creates a choke point for electromagnetic interference. High-frequency noise encounters resistance, while low-frequency signals pass through unaffected. This makes ferrite beads ideal for suppressing noise in power lines, USB cables, and audio circuits.Ferrite beads come in various shapes and sizes, each designed for specific applications. For example, cylindrical beads are common in power cords, while clip-on beads are used for retrofitting existing cables. Choosing the right ferrite bead depends on the frequency range and noise level of your circuit.Tip: When selecting ferrite beads, check their impedance at the target frequency. Higher impedance means better noise suppression.Varistors: Protecting against voltage spikes.Varistors are essential for protecting electronic devices from voltage spikes. These components act like electrical safety valves, absorbing excess energy during sudden surges. You’ll often see them in EMI/EMC Filters, where they safeguard sensitive circuits from damage.Varistors exhibit sharp voltage breakdown characteristics, similar to back-to-back Zener diodes. Multilayer varistors (MLVs) are particularly effective because they can withstand thousands of strikes at full rated peak current without degrading. Their response time is less than one nanosecond, making them ideal for fast voltage spike protection.Modern MLVs also feature reduced self-inductance, which minimizes voltage overshoot during spikes. This improvement ensures reliable performance in high-speed circuits. You’ll find varistors in applications ranging from consumer electronics to industrial machinery, where they protect against sudden power fluctuations.Key advantages of varistors:Symmetrical voltage breakdown for consistent protection.High durability under repeated surges.Ultra-fast response time for immediate action.Reduced self-inductance for better performance.Note: Always choose varistors with a voltage rating slightly higher than your circuit’s operating voltage. This ensures optimal protection without interfering with normal operation.How EMI/EMC Filters WorkThe basic working principle of EMI/EMC filtersEMI/EMC filters work by suppressing electromagnetic noise in electronic circuits. They allow desirable currents to flow while diverting unwanted currents to the ground. These filters are typically low-pass filters, meaning they let lower frequencies pass through while blocking higher frequencies that cause interference. This ensures that your devices operate without disruptions from external noise.To achieve this, EMI/EMC filters use passive components like capacitors and inductors. Capacitors create a low-impedance path for high-frequency noise, directing it away from sensitive components. Inductors, on the other hand, resist changes in current, blocking high-frequency signals. Together, these components form LC circuits that filter out harmful noise while allowing the desired signals to pass.Key principles of EMI/EMC filters:Suppress electromagnetic noise through conduction.Divert unwanted currents to the ground or back to the source.Allow AC line frequencies to pass while blocking harmful high frequencies.For example, in DC motors, EMI filters act as bypass components. They allow DC current to flow without affecting the motor's performance. At the same time, they reduce internal EMI through field cancellation, ensuring smooth operation.How filters suppress conducted and radiated interferenceEMI/EMC filters are designed to tackle two types of interference: conducted and radiated. Conducted interference travels through wires or cables, while radiated interference spreads through the air. These filters suppress both types by using a combination of capacitors, inductors, and other components.Conducted interference is often addressed by placing capacitors between power lines and the ground. For instance, Y-capacitors are highly effective in reducing common-mode noise, which flows between a conductor and the ground. Inductors are also used to block high-frequency noise in power lines, ensuring that only the desired signals reach your devices.Radiated interference, on the other hand, is suppressed by creating barriers that absorb or redirect electromagnetic waves. Ferrite beads, for example, are commonly used to reduce high-frequency noise in cables. They create a choke point for interference, allowing low-frequency signals to pass through while blocking unwanted noise.Frequency (MHz)Capacitor Value (pF)Inductor Value (nH)Insertion Loss Requirement30> 86< 327< 1167> 30< 30< 1At 30 MHz, a 470pF Y-capacitor shows lower impedance, enhancing EMI suppression. At 167 MHz, a 100pF Y-capacitor demonstrates superior performance. These components effectively reduce both conducted and radiated EMI across various frequency bands, ensuring reliable device operation.The importance of proper placement and designThe placement and design of EMI/EMC filters play a crucial role in their effectiveness. Improper placement can lead to reduced performance or even failure to suppress interference. To optimize filter performance, you need to understand the type of interference and the frequency behavior of your circuit.For example, placing filters close to the source of interference minimizes the distance that noise can travel. This reduces the risk of interference affecting other components. Additionally, designing filters with the right combination of capacitors, inductors, and resistors ensures that they target the specific frequency range of the noise.Simulation tools can also help you optimize filter design. By accounting for parasitic elements, these tools allow you to predict how the filter will perform in real-world conditions. This approach not only improves performance but also reduces development time and costs.Tips for effective filter placement and design:Place filters close to the source of interference.Use simulation tools to optimize performance.Choose components based on the specific noise profile of your application.Proper placement and design ensure that EMI/EMC filters meet product certification standards.

It’s an exciting process, and you’ll learn a lot along the way!Basics of Programming an Atmel MicrocontrollerUnderstanding inputs, outputs, and decision-makingWhen you program an Atmel microcontroller, you’re essentially teaching it how to interact with the world. It does this through inputs and outputs. Inputs are signals or data the microcontroller receives, like a button press or a temperature reading. Outputs are actions it performs, like turning on an LED or activating a motor.Decision-making is where the magic happens. The microcontroller processes inputs and decides what to do based on the code you write. For example, you can program it to turn on a fan if the temperature gets too high. This logic is the foundation of AVR programming and allows you to create smart, responsive systems.Tip: Start with simple input-output tasks, like reading a button press and lighting up an LED. It’s a great way to understand how decision-making works in AVR MCU programming.Introduction to microcontroller pins and their functionsEvery Atmel microcontroller has pins, which are tiny connectors that let it communicate with the outside world. These pins can serve different purposes, depending on how you configure them in your code.Here’s a quick breakdown of common pin types:Digital Pins: Used for simple on/off signals, like turning an LED on or off.Analog Pins: Measure varying signals, like the output from a temperature sensor.Power Pins: Provide power to the microcontroller and connected components.Special Function Pins: Handle advanced features like PWM (Pulse Width Modulation) or serial communication.Understanding these pins is crucial for AVR programming. For instance, if you want to control an LED, you’ll need to connect it to a digital pin and configure that pin as an output in your code.Writing a simple program: Turning an LED on and offLet’s write your first program to turn an LED on and off. This is a classic beginner project in AVR programming. Here’s how you can do it using the Arduino IDE:void setup() { pinMode(13, OUTPUT); // Set pin 13 as an output}void loop() { digitalWrite(13, HIGH); // Turn the LED on delay(1000); // Wait for 1 second digitalWrite(13, LOW); // Turn the LED off delay(1000); // Wait for 1 second}In this code:The setup() function runs once and configures pin 13 as an output.The loop() function runs repeatedly, turning the LED on and off with a 1-second delay.Upload this code to your microcontroller, and watch the LED blink. It’s a simple yet satisfying way to start your AVR programming journey!Pro Tip: If the LED doesn’t blink, double-check your connections and ensure you’ve selected the correct board and port in the Arduino IDE.Step-by-Step Programming ProcessImage Source: unsplashWriting and editing code in C or Arduino languageWhen it comes to AVR programming, writing code is where the fun begins! You can use either the C language or the Arduino language, depending on your comfort level. If you're new, the Arduino language is a great starting point because it’s simple and beginner-friendly. On the other hand, C gives you more control and flexibility for advanced projects.To start writing code, open your chosen software tool (like the Arduino IDE or Microchip Studio). Begin with a basic program, such as blinking an LED. For example, in C, you might write something like this:#include <avr/io.h>#include <util/delay.h>int main(void) { DDRB |= (1 << PB0); // Set pin PB0 as output while (1) { PORTB |= (1 << PB0); // Turn LED on _delay_ms(1000); // Wait 1 second PORTB &= ~(1 << PB0); // Turn LED off _delay_ms(1000); // Wait 1 second }}This code sets up pin PB0 as an output and toggles it on and off every second. If you're using the Arduino language, the process is even simpler, as shown in the previous section.Tip: Save your code frequently. It’s a good habit that can save you from losing progress.Compiling and debugging the programOnce you’ve finished writing your code, it’s time to compile it. Compiling converts your code into a format the microcontroller can understand. In the Arduino IDE, this happens automatically when you click the "Verify" button. In Microchip Studio, you’ll need to select "Build Solution" from the menu.If there are errors, don’t worry! Debugging is a normal part of programming. Look at the error messages carefully—they usually tell you what went wrong. Common issues include missing semicolons, incorrect pin numbers, or typos in your code.Here’s a quick checklist for debugging:Double-check your syntax.Verify that you’ve selected the correct microcontroller model in your software.Ensure all libraries or headers (like <avr/io.h>) are included.Pro Tip: If you’re stuck, search online forums or communities. Many AVR programming enthusiasts are happy to help.Uploading the code to the AVR microcontrollerAfter compiling and debugging, the next step is uploading your code to the AVR microcontroller. If you’re using an Arduino board, this is as simple as clicking the "Upload" button in the Arduino IDE. The built-in programmer handles the rest.For standalone AVR microcontrollers, you’ll need an external programmer like USBasp. Connect the programmer to your microcontroller and computer, then use your software tool to upload the code. In Microchip Studio, this involves selecting "Start Without Debugging" or a similar option.Once the upload is complete, your microcontroller will start running the program immediately. If you’ve written a blinking LED program, you should see the LED turning on and off as expected.Note: If the upload fails, check your connections and ensure the programmer is compatible with your microcontroller.By following these steps, you’ll master the basics of writing, compiling, and uploading code to an Atmel microcontroller. It’s a rewarding process that gets easier with practice!Testing and verifying the outputOnce you’ve uploaded your code to the microcontroller, it’s time to test and verify the output. This step ensures your program works as expected and helps you catch any mistakes.Step 1: Observe the OutputStart by watching the behavior of your microcontroller. If you’ve programmed an LED to blink, check if it’s turning on and off at the right intervals. For more complex projects, like reading sensor data, look for the expected changes in output.Tip: Keep your setup simple for testing. Fewer components mean fewer chances for errors.Step 2: Use Debugging ToolsIf the output doesn’t match your expectations, don’t panic. Debugging tools can help you figure out what’s wrong. For example, the Arduino IDE has a built-in Serial Monitor. You can use it to print messages from your microcontroller and see what’s happening inside. Add lines of code like this to your program:void setup() { Serial.begin(9600); // Start serial communication pinMode(13, OUTPUT); // Set pin 13 as an output}void loop() { Serial.println("LED is ON"); // Print message digitalWrite(13, HIGH); // Turn LED on delay(1000); // Wait for 1 second Serial.println("LED is OFF"); // Print message digitalWrite(13, LOW); // Turn LED off delay(1000); // Wait for 1 second}This code sends messages to the Serial Monitor, letting you track the LED’s status.Step 3: Adjust and RetestIf something isn’t working, double-check your connections and code. Look for loose wires or incorrect pin numbers. Once you’ve made adjustments, upload the code again and test it. Repeat this process until everything works perfectly.Pro Tip: Testing isn’t just about fixing errors. It’s also a chance to learn how your microcontroller responds to different inputs and outputs.By following these steps, you’ll gain confidence in verifying your microcontroller’s output. Testing is a crucial part of programming, and it gets easier with practice!Troubleshooting and Overcoming ChallengesCommon beginner mistakes and how to avoid themWhen you're starting out with AVR microcontrollers, it's easy to make a few common mistakes. Don’t worry—it happens to everyone! One frequent issue is forgetting to select the correct microcontroller model or port in your software. If your program doesn’t upload, double-check these settings first. Another mistake is wiring components incorrectly. A loose connection or reversed polarity can stop your project from working. Always double-check your circuit before powering it up.Another pitfall is skipping the basics. As a beginner, you might feel tempted to dive into complex projects right away. Instead, start small. Focus on simple tasks like blinking an LED or reading a button press. These projects build your confidence and help you understand how AVR microcontrollers work.Tip: Keep a checklist of steps for setting up your hardware and software. It’ll save you time and frustration.Debugging tips for hardware and software issuesDebugging is a crucial skill in programming. If something isn’t working, don’t panic—break the problem into smaller parts. Start by checking your hardware. Are all the wires connected properly? Is the power supply working? Use a multimeter to test your circuit if needed.For software issues, look at your code. Did you miss a semicolon or use the wrong pin number? Tools like the Arduino IDE’s Serial Monitor can help you see what’s happening inside your microcontroller. Add lines like Serial.println("Step 1 complete"); to track your program’s progress.Pro Tip: Change one thing at a time when debugging. It’s easier to pinpoint the problem that way.Finding help and support in online communitiesYou’re not alone in your AVR programming journey.

IntroductionWhat is the IC package? To put it simply, chip packaging is the process of placing a bare integrated circuit chip produced in a foundry on a load-bearing substrate, leading the pins out, and then fixing the package as a whole. It is analogous to the chip's shell, which can wrap, fix, and seal the chip to protect it from external forces such as water, air, moisture, chemicals, and so on.With the continuous improvement of IC packaging, there are more and more types of IC packaging. Various IC packaging packages types, names, logos, etc. can sometimes be confusing. This blog will give you a brief introduction to IC packaging related content, which mainly includes the following three parts: common IC brand identification, IC package terminology, classification of IC packaging, and hope to help you further effectively distinguish and understand IC packaging. Catalog IntroductionEvolution of IC Packaging TypeIC Packaging Types10 Common IC Brand Identification71 kinds of IC package terminology   explainedFAQ Evolution of IC Packaging TypeIn the early stage of the development of chip packaging, there are mainly two types: 1. Through-hole package2. Surface mount packageThrough hole package mainly includes Dual In-line Package (DIP), Transistor Outline (TO), Pin Grid Array (PGA) and so on. Through-hole packageSurface mount package includes TO-252 (D-PAK), Small-Outline Transistor (SOT), Small Outline Package (SOP), Plastic Quad Flat Package (QFP), Plastic Leaded Chip Carrier (PLCC) and so on.Surface mount packageDue to the increasing demand of the surface mount market, the earlier through-hole TO packaging has also begun to develop to the surface mount mode. For example, DPAK packaging, which is easy for many people to confuse, actually refers to TO-252, D2PAK refers to TO-263 and D3PAK refers to TO-268.In the middle and later stage, chip packaging began to enter the era of area array packaging. During this period, packaging types such as Ball Grid Array Package (BGA), Chip Scale Package (CSP), Quad Flat No-lead Package (QFN) and Multi-Chip Module (MCM) began to become popular.With the further development of packaging technology, some chips have begun to adopt the latest three-dimensional stacking packaging technology. IIC Packaging TypesAccording to the different port direction, the common IC packages can be divided into four categories: unilateral, bilateral, four-sided and matrix and several types can be subdivided from the above four categories according to different packaging forms and port shapes. Please refer to the following table for details. IC packaging types In addition, according to the material medium, IC packaging can also be divided into metal, ceramic, plastic and other types, generally distinguished by prefix. For example, "C" refers to ceramic package, "H" refers to package with heat sink and "P" refers to plastic package. 10 Common IC Brand IdentificationMany integrated circuit models’ prefix is often the abbreviation of the manufacturer's name. If you see the following prefix model, you might as well check the corresponding brand first. Of course, this method is not entirely feasible. So you still have to refer to the PDF file of the specific product according to the actual situation.1. AMDThose prefixed with AM are all AMD products, and there are also some confusion between the prefix PAL, CYPRESS and TI. The specific situation should be determined by checking the information.2. ATMELThose prefixed with AT are ATMEL products.3. CYPRESSThose prefixed with CY are all CYPRESS products, and some of them are confused with prefix PALC, PALCE and TI.4. NSCThose prefixed with DM, LF, LM, DS, etc., are basically NSC products. NSC has many product series with other prefix, but the specific situation should be determined by checking the information.5. AD：Those prefixed with AD, OP are AD brand. AD has many other series, such as prefix: DAC, ADG, ADSP and many other series.6. INTERSIL：Those prefixed with HI1, HI2, HI3, HI4, HA1, HA2, HA3, HA4, CA, ICL, ICM, ID, IS, etc., are INTERSIL products. There is also some confusion between prefix MD and INTEL.7. IDT：The prefix for IDT products is almost the prefix IDT.8. MAXThe prefix for MAX products is almost the prefix MAX.9. AGILENTCommon prefixes are HCPL, HDSP, HSSR, and so on.10. ALTERAThe prefix for ALTERA products is almost the prefix for EPM. IC package Figure (105 kinds in total)71 kinds of IC package terminology explainedStill not sure what some IC packaging terms mean exactly? Here is a list of 71 common IC packaging terms for you.1. BGA (Ball Grid Array)BGA is one of the surface mount packages. Spherical bumps are made on the back of the printed substrate to replace pins. LSI chips are assembled on the front of the printed substrate, and then sealed by molding resin or filling method. It is also known as Pad Array Carrier (PAC) and the number of pins can exceed 200. It is a kind of package for multi-pin LSI.The package was developed by Motorola and was first used in portable phones and other devices. 2. BQFP (Quad Flat Package with Bumper)BQFP is one of the QFP packages that is provided with protrusions (cushions) at the four corners of the package body to prevent bending deformation of the pins during transportation. American semiconductor manufacturers mainly use this package in microprocessors and Asic circuits. The center distance of the pin is 0.635 mm, and the number of pins ranges from 84 to 196. (see QFP). 3. Butt Joint PGA (Butt Joint Pin Grid Array)Butt Joint PGA is an alias for surface mount PGA (see Surface Mount PGA) 4. C- (Ceramic)C- is a mark that represents a ceramic package and is often used in practice. For example, CDIP represents Ceramic DIP. 5. CerdipThe Ceramic Dual In-line Package sealed with glass is for circuits such as ECL RAM, DSP (Digital Signal Processor). Cerdip with glass window is used for ultraviolet erasing EPROM and microcomputer circuit with EPROM. The center distance of the pin is 2.54 mm, and the number of pins ranges from 8 to 42. In Japan, this package is represented as DIP-G (G means glass seal). 6. CerquadOne of the surface mount packages, that is, the lower sealed Ceramic QFP, is used to package logic LSI circuits such as DSP. Cerquad with windows is used to package EPROM circuits. The heat dissipation is better than that of Plastic QFP, and power ranges from 1.5 to 2W can be allowed under natural air cooling conditions. But the cost of packaging is 3 to 5 times higher than that of Plastic QFP. Pin center distance has 1.27 mm, 0.8 mm, 0.65 mm, 0.5 mm, 0.4 mm and other specifications. The number of pins ranges from 32 to 368. 7. CLCC (Ceramic Leaded Chip Carrier)Ceramic Leaded Chip Carrier is one of the surface mount packages, and the pins are drawn from the four sides of the package in T-shaped. Those with windows are used for packaging ultraviolet erasing EPROM and microcomputer circuit with EPROM, etc. This packaging is also known as QFJ and QFJ-G (see QFJ). 8. COB (Chip on Board)Chip on Board package is one of the bare chip mounting technologies. The semiconductor chip is connected and mounted on the printed circuit board, the electrical connection between the chip and the substrate is realized by the lead stitching method. Next, cover it with resin to ensure its reliability. Although COB is the simplest bare chip mounting technology, its packaging density is far lower than that of TAB and reverse chip welding technology. 9. DFP (Dual Flat Package)Dual Flat Package is another name for SOP (see SOP). This was once called in the past, but now it is basically out of use.10. DIC (Dual In-line Ceramic Package)This is another name for Ceramic DIP (including glass seal) (see DIP). 11. DIL (Dual In-Line)DIL is an alias for DIP (see DIP). European semiconductor manufacturers often use this name. 12. DIP (Dual In-line Package)Dual In-line Package is one of the through hole packages. The pins are drawn from both sides of the package, and the packaging materials are plastic and ceramic. DIP is the most popular through-hole package, including standard logic IC, memory LSI, microcomputer circuit and so on. The center distance of the pin is 2.54 mm, and the number of pins ranges from 6 to 64. The packaging width is usually 15.2 mm. Some refer to packages with widths of 7.52 mm and 10.16 mm as skinny DIP and slim DIP (narrow DIP, respectively). In most cases, however, it is indistinguishable and is simply collectively referred to as DIP. In addition, Ceramic DIP sealed with low melting point glass is also known as Cerdip (see Cerdip). 13. DSO (Dual Small Out-lint)DSO is the alias for SOP (see SOP). Some semiconductor manufacturers use this name. 14. DICP (Dual Tape Carrier Package)DICP is one of the TCP (loaded packages). The pins are made on the insulation tape and drawn from both sides of the package. Due to the use of TAB (Tape Automated Bonding) technology, the package shape is very thin. It is commonly used in liquid crystal display drive LSI, but most of them are customized products. In addition, the 0.5 mm thick memory LSI thin package is in the development stage. In Japan, DICP is named DTP according to the standard of EIAJ (Japanese Electronic Machinery Industry). 15. DIP (Dual Tape Carrier Package)As we mentioned above, it is the name of DTCP in the standard of the Japanese Electronic Machinery Industry Association. (see DTCP). 16. FP (Flat Package)FP is one of the surface mount packages and it is another name of QFP or SOP (see QFP and SOP). Some semiconductor manufacturers use this name.17. Flip-chipFlip-chip is one of the bare chip packaging technologies. The metal bump is made in the electrode region of the LSI chip, and then the metal bump is connected to the electrode area on the printed substrate by pressure welding. The occupied area of packaging is basically the same as the size of the chip, which is the smallest and thinnest of all packaging technologies. 18. FQFP (fine pitch quad flat package)FQFP usually refers to the QFP which the center distance of the pin is less than 0.65 mm (see QFP). Some conductor manufacturers use this name.19. CPAC (Globe Top PAD Array Carrier)CPAC is another name for BGA by Motorola in the United States. 20. CQFP (Quad Fiat Package with Guard Ring)CQFP is one of the plastic QFP. The pins are masked with a resin protective ring to prevent bending deformation. Before assembling the LSI on the printed substrate, we need to cut off the pin from the protective ring and make it become L-shaped. This package has been mass produced by Motorola in the United States. The center distance of the pin is 0.5 mm, and the maximum number of pins is about 208.21. H- (with heat sink)H- represents a mark with a heat sink. For example, HSOP represents a SOP with a heat sink.22. Pin Grid Array (surface mount type)PGA is usually a through-hole package with a pin length of about 3.4 mm. The surface mount PGA has display–shaped pins on the bottom of the package, ranging in length from 1.5 mm to 2.0 mm. Mounting uses the method of butt joint with the printed substrate, so it is also known as butt joint PGA. Because the center distance of the pin is only 1.27 mm, which is half smaller than the through-hole PGA, the package body cannot be made very large, and the number of pins is more than the through-hole type (ranges from 250 to 528). It is a package for large-scale logical LSI. The packaging substrate has a multi-layer ceramic substrate and a glass epoxy resin printing base. Packaging based on multi-layer ceramic substrate has been practical. 23. JLCC (J-Leaded Chip Carrier)JLCC refers to the alias for windowed CLCC and windowed Ceramic QFJ (see CLCC and QFJ). The name used by some semiconductor manufacturers. 24. LCC (Leadless chip carrier)LCC refers to a surface mount package with only electrode contact and no pin on the four sides of the ceramic substrate. It is a high-speed and high-frequency IC package, also known as Ceramic QFN or QFN-C (see QFN). 25. LGA (Land Grid Array)LGA , that is, an array state flat electrode contact package made on the bottom surface. All we need to do is to insert the socket when assembling. Ceramic LGA, with 227 contacts (1.27 mm center distance) and 447 contacts (2.54 mm center distance) has been used in high speed logic LSI circuits. LGA can accommodate more input and output pins in a smaller package than QFP. In addition, because of the small impedance of the lead, it is very suitable for high-speed LSI. However, due to the complexity of socket production and high cost, it is basically not used much now. But the demand for it is expected to increase in the future. 26. LOC (Lead on Chip)LOC is one of the LSI packaging technologies. The front end of the lead frame is located at the top of the chip. A convex solder joint is made near the center of the chip, and the lead is stitched for electrical connection. Compared with the original structure in which the lead frame is arranged near the side of the chip, the chip contained in the package of the same size is up to about 1 mm wide. 27. LQFP (Low Profile Quad Flat Package)LQFP is a kind of QFP whose package body thickness is 1.4 mm and this is the name used by the Japanese Electronics and Machinery Industry according to the new QFP shape specification. 28. L-QUADL-QUAD is one of the Ceramic QFP. The thermal conductivity of aluminum nitride for packaging substrate is 7 to 8 times higher than that of alumina and has good heat dissipation. The frame of the package is sealed with alumina and the chip is sealed by filling method, thus the cost is suppressed. It is a package developed for logical LSI that allows 3 w power under natural air cooling conditions. LSI logic packages with 208 pins (0.5 mm center distance) and 160 pins (0.65 mm center distance) have been developed and put into mass production in October 1993. 29. MCM (Multi-Chip Module)MCM is a package that assembles multiple bare semiconductor chips on a wiring substrate. According to the substrate materials, it can be divided into MCM-L, MCM-C and MCM-D. MCM-L is a module that uses the usual glass epoxy resin multi-layer printed substrate. The wiring density is not that high and the cost is low. MCM-C is a module which uses thick film technology to form multi-layer wiring and uses ceramics (alumina or glass-ceramic) as substrate, which is similar to mixing IC with thick film of multi-layer ceramic substrate. There is no significant difference between them, and the wiring density was higher than that of MCM-L.MCM-D is a module which uses thin film technology to form multi-layer wiring and uses ceramics (alumina or aluminum nitride) or Si and Al as substrate. The wiring density is the highest of the three modules, but the cost is also high. 30. MFP (Mini Flat Package)MFP is another name for plastic SOP or SSOP (see SOP and SSOP) and it is used by some semiconductor manufacturers. 31. MQFP (Metric Quad Flat Package)MQFP is a classification of QFP according to the JEDEC standard. It refers to standard QFP with a pin center distance of 0.65 mm and a body thickness of 3.8 mm~2.0 mm (see QFP). 32. MQUAD (Metal Quad)MQUAD is a kind of QFP package developed by Olin Company in the United States. The substrate and cover are made of aluminum and sealed with adhesive. The power of 2.5 w~2.8 w can be allowed under the condition of natural air cooling. SHINKO ELECTRIC INDUSTRIES CO., LTD. was licensed to start production in 1993. 33. MSP (Mini Square Package)MSP is another name for QFI (see QFI) and is often called in the early days of development. QFI is the name specified by the Electronic Machinery Industry Association of Japan. 34. OPMAC (Over Molded Pad Array Carrier)OPMAC is the name used by Motorola for molded resin seal BGA (see BGA). 35. P- (plastic)P- is the mark that represents a plastic package. For example, PDIP represents Plastic DIP. 36. PAC (Pad Array Carrier)PAC is an alias for BGA (see BGA). 37. PCLP (Printed Circuit Board Leadless Package)Fujitsu of Japan uses the name for Plastic QFN (Plastic LCC) (see QFN). The center distance of the pin can be divided into two specifications: 0.55 mm and 0.4 mm. It is currently in the development phase. 38. PFPF (Plastic Flat Package)PFPF is an alias for Plastic QFP (see QFP) and it is used by some LSI manufacturers. 39. PGA (Pin Grid Array)PGA is one of the through-hole packages, and the vertical pins on the bottom are arranged in the form of display. The packaging substrate is basically multi-layer ceramic substrate. In the case of not specifically indicating the name of the material, most of the Ceramic PGA, are used in high-speed and large-scale logic LSI circuits. The cost is high. The center distance of the pin is usually 2.54 mm, and the number of pins ranges from 64 to 447. In order to reduce the cost, the packaging substrate can be replaced by glass epoxy resin printing substrate. There is also Plastic PGA with 64 to 256 pins. In addition, there is a short pin surface mount PGA (Butt Joint PGA) with a pin center distance of 1.27 mm. (see Surface Mount PGA). 40. Piggy BackIt refers to a ceramic package with sockets and its shape is similar to that of DIP, QFP and QFN. It is used to confirm operation on the evaluation program when developing a device with a microcomputer. For example, plug the EPROM into the socket for debugging. This kind of package is basically custom-made, and there is little circulation on the market. 41. PLCC (Plastic Leaded Chip Carrier)PLCC is one of the surface mount packages. The pin is drawn from the four sides of the package in the shape of T and is made of plastic. Texas Instruments was first used in 64k-bit DRAM and 256k-bit DRAM, and now it has been widely used in logic LSI, DLD (or logic device) and other circuits. The center distance of the pin is 1.27 mm, and the number of pins ranges from 18 to 84. The J-shaped pin is not easy to deform and is easier to operate than QFP, but the appearance inspection after welding is more difficult.PLCC is similar to LCC (also known as QFN). In the past, the only difference between the two was that the former used plastic and the latter used ceramics. But now there are J-shaped pin packages made of ceramics and pin-free packages made of plastic. (marked as plastic LCC, PC LP, P-LCC, etc.) Thus they have been unable to distinguish.To this end, the Japanese Electronics and Machinery Industry decided in 1988 to refer to packages with J-shaped pins on four sides as QFJ, and packages with electrode bumps on four sides as QFN (see QFJ and QFN). 42. P-LCC (Plastic Leadless Chip Carrier)Sometimes it is another name for Plastic QFJ, sometimes it is another name for QFN (Plastic LCC) (see QFJ and QFN). Some LSI manufacturers use PLCC for lead package and P-LCC for lead-free package to show the difference. 43. QFH (Quad Flat High Package)QFH is a kind of Plastic QFP. In order to prevent the package body from breaking, the QFP body is made thicker (see QFP). This is the name used by some semiconductor manufacturers. 44. QFI (Quad Flat I-leaded Package)QFI is one of the surface mount packages. The pin is drawn from the four sides of the package in I-shaped. It is also known as MSP (see MSP). The mount is connected with the printed substrate by butt joint. Because there is no protruding part of the pin, the occupied area of the mount is smaller than that of QFP. Hitachi has developed and used this package for video analog IC. In addition, this package is also used by PLL IC of Motorola, a Japanese company. The center distance of the pin is 1.27 mm, and the number of pins is from 18 to 68.45. QFJ (Quad Flat J-leaded Package)QFJ is one of the surface mount packages. The pin is drawn from the four sides of the package in the shape of J. It is the name stipulated by the Japan Electronic Machinery Industry Association. The center distance of the pin is 1.27 mm. There are two kinds of materials: plastic and ceramics. Plastic QFJ is mostly called PLCC (see PLCC), and it is for microcomputers, gate displays, DRAM, ASSP, OTP, etc. The number of pins ranges from 18 to 84. Ceramic QFJ is also known as CLCC and JLCC (see CLCC). The windowed package is used for ultraviolet erasing EPROM and microcomputer chip circuits with EPROM. The number of pins ranges from 32 to 84.46. QFN (Quad Flat Non-leaded Package)QFN is one of the surface mount packages and it is often called LCC now. QFN is the name specified by the Electronic Machinery Industry Association of Japan. The four sides of the package are equipped with electrode contacts. Because there are no pins, the mounting area is smaller than QFP, and the height is lower than QFP. However, when there is a stress between the printed substrate and the package, it cannot be alleviated at the electrode contact. Therefore, it is difficult for electrode contacts to make as many pins as QFP. The number of pins is generally ranges from 14 to 100.There are two kinds of materials: ceramic and plastic. When marked with LCC, they are basically Ceramic QFN. The center of the electrode contact is 1.27 mm.Plastic QFN is a low-cost package for printing substrate with glass epoxy resin. In addition to 1.27 mm, there are two kinds of electrode contact center distance: 0.65 mm and 0.5 mm. This package is also known as Plastic LCC, PCLC, P-LCC and so on.47. QFP (Quad Flat Package)QFP is one of the surface mount packages, with pins drawn from four sides in L-shaped. There are three kinds of substrate: ceramic, metal and plastic. In terms of quantity, plastic packaging accounts for the vast majority. When the material is not specifically indicated, most of the cases are Plastic QFP. Plastic QFP is the most popular multi-pin LSI package. It is not only used in microprocessor, gate display and other digital logic LSI circuits, but also in VTR signal processing, audio signal processing and other analog LSI circuits. The center distance of pin has 1.0 mm, 0.8 mm, 0.65 mm, 0.5 mm, 0.4 mm, 0.3 mm and other specifications. The maximum number of pins in the 0.65 mm center distance specification is 304.In Japan, QFP with a pin center distance less than 0.65 mm is called QFP (FP). But now the Japanese Electronics and Machinery Industry will re-evaluate the shape of the QFP. There is no difference in the center distance of the pin. But according to the thickness of the package body, it can be divided into three types: QFP (2.0 mm~3.6 mm thickness), LQFP (1.4 mm thickness) and TQFP (1.0 mm thickness).In addition, some LSI manufacturers specifically refer to the QFP with the pin center distance as 0.5 mm as shrink QFP or SQFP, VQFP.However, some manufacturers also call the QFP with pin center distance of 0.65 mm and 0.4 mm SQFP, which makes the name a little confused. The disadvantage of QFP is that when the center distance of the pin is less than 0.65 mm, the pin is easy to bend. In order to prevent pin deformation, several improved QFP varieties have emerged such as BQFP with tree finger buffer pads on the four corners of the package (see BQFP); GQFP with a resin protection ring which covers the front of the pin (see GQFP) and TPQFP (see TPQFP)，which is set test bumps in the package body and can be tested in a special fixture to prevent pin deformation.In the aspect of logical LSI, many development products and highly reliable products are packaged in multi-layer ceramic QFP. Products with a minimum pin center distance of 0.4 mm and a maximum number of pins of 348 have also been introduced. In addition, there are glass-sealed ceramic QFP.48. QFP (FP) (QFP fine pitch)This is the name specified in the standard of the Japan Electronic Machinery Industry Association.

Hitachi uses this package in analog IC (IC for motor drive).65. SOIC (Small Out-line Integrated Circuit)SOIC is an alias for SOP (see SOP). Many semiconductor manufacturers abroad use this name.66. SOJ (Small Out-Line J-Leaded Package)SOJ is one of the surface mount packages. The pin is J-shaped from both sides of the package, so it gets its name. They are usually plastic products and are used in memory LSI circuits such as DRAM and SRAM. But most of them are used in DRAM.Many of the DRAM devices packaged in SOJ are mounted on SIMM. The center distance of the pin is 1.27 mm, and the number of pins ranges from 20 to 40 (see SIMM).67. SOL (Small Out-Line L-leaded Package)The name used for SOP in accordance with the JEDEC standard (see SOP).68. SONF (Small Out-Line Non-Fin)SONF is the SOP without heat sink. As the same as the usual SOP, the NF (non-fin) mark is intentionally added In order to show that there is no heat sink in the power IC package. The name is used by some semiconductor manufacturers (see SOP).69. SOF (Small Out-Line Package)SOF is one of the surface mount packages with pins drawn from both sides of the package in L-shaped.

In the future, mankind is about to enter a new era, the era of flexible electronics. Flexible electronic devices that are as soft as human skin will be the next development trend of the electronics industry, and may even subvert human life. Catalog I What is Flexible electronics?II Applications of flexible electronics2.1 Flexible electronic display2.2 Thin film solar panels2.3 RFID2.4 Electronic skinIII ConclusionFAQ  I What is Flexible electronics? The concept of flexible electronics started in the 1980s, when people tried to replace inorganic semiconductors such as silicon with organic semiconductors, so that organic electronic devices have flexible characteristics.Flexible electronic technology is a brand-new electronic technology revolution. It is an emerging electronic technology that makes organic and inorganic materials electronic devices on flexible, malleable plastic or thin metal substrates. It has a wide range of fields in information, energy, medical treatment, and national defense.  Applications of flexible electronics In addition to integrating electronic circuits, functional materials, micro-nano manufacturing and other fields of technology, flexible electronic technology also spans industries such as semiconductors, packaging, testing, materials, chemicals, printed circuits, and display panels. Not only that, it can also help the transformation and upgrading of traditional industries, such as plastics, printing, chemicals, and metal materials.By improving its performance and industrial added value, flexible electronics will frequently appear in human life, bringing revolutionary changes to the industrial structure and future life. As technology upgrades, flexible electronics materials research and development and rich application products have emerged.II Applications of flexible electronicsWith the development of flexible electronic technology, various electronic products have emerged. Just as microelectronics technology provides a technology platform for large-scale integrated circuits and computer chip technologies, flexible electronic technology provides a brand-new technological platform for the research and development of new products. 2.1 Flexible electronic displayThe flexible electronic display is a brand-new product developed on the flexible electronic technology platform. Unlike traditional flat-panel displays, such displays can be repeatedly bent and folded, thus bringing great convenience to our lives.For example, all visual materials, including books, newspapers, magazines, and video files, can be presented on this display and can be viewed anytime, anywhere. Although current popular MP4 players and personal digital assistants (PDAs) can meet such use needs, the display screen cannot be bent and folded, and can only be read and viewed in a small screen area. And video, visual effects are greatly constrained. In contrast, flexible electronic displays have unparalleled advantages. They are like newspapers. When they are needed, they are unfolded. When they are used, they are curled or even folded. This guarantees the convenience of portability while giving full consideration to the visual effects.Flexible electronic displaySamples of flexible electronic displays have been successfully developed and it is believed that it will be a long way from entering the market. It is worth mentioning that flexible electronic displays use more lightweight organic materials instead of inorganic materials, so their weight is lighter than traditional displays, and this feature helps to improve their portability. In addition, the use of high molecular organic materials offers possibilities for reducing costs. In addition, the flexible electronic display has the characteristics of a thin thickness, and its thickness can be much smaller than that of the popular liquid crystal display. Therefore, another name of the flexible electronic display is a paper-like electronic display.2.2 Thin film solar panelsThin film solar panel is another specific application of flexible electronics technology. In today's world, energy has become a topic of global concern. China not only faces energy shortages but also faces environmental pollution. As a clean energy source, solar energy can effectively alleviate the contradiction of energy shortage under the premise of zero environmental pollution.As the most common way to use solar energy, solar panels can cover a large area at the lowest cost to effectively use solar energy. At present, thin film amorphous Sili-Con solar panels have been successfully developed and marketed. Thin film solar panel Thin-film solar panels based on flexible electronic technology can meet high-power generation needs, such as the use of thin-film solar panels in solar power plants in sunny desert areas.In addition, it can also make full use of its flexible and lightweight features to integrate it into clothing. Putting on such clothes to walk or exercise in the sun, the power of small appliances (such as MP3 players and laptops) that are carried around can be supplied by the thin-film solar panels on the clothes, thus achieving the purpose of saving and environmental protection.2.3 RFIDRadio frequency identification (RFID) technology can be used to complete information input and processing, fast and convenient operation, and rapid development without manual contact, and is widely used in production, logistics, transportation, medical, food, security and other fields. RFID systems usually consist of transponders and readers.The electronic tag is one of many forms of transponder, and can be understood as a transponder with a thin film structure, which has the characteristics of convenient use, small size, thin and light, and can be embedded in the product. More and more electronic tags will be used in future RFID systems.Flexible Electronics in RFIDIn this response to Covid-19, flexible electronic technology has played a huge role in body temperature measurement.Group body temperature measurement has problems such as huge number of monitoring people, cumbersome temperature measurement work, and difficulty in continuous temperature recording. Wearable temperature measuring stickers made by introducing flexible electronic technology can record and analyze the body temperature data of the target population. In this way, potential threats can be discovered and eliminated through long-term monitoring, thereby helping management departments to achieve personnel management monitoring.2.4 Electronic skinAnother important application of flexible electronics is electronic skin. Electronic skin, also called skin-like electrons, is basically characterized in that various electronic components are integrated on a flexible substrate to form a skin-like circuit board, which has high flexibility and elasticity like skin and can be used in many other applications. electrical equipment.It can be said that the potential of flexible electronic skin is great. With the popularization of technologies such as smart medical care, virtual reality, and artificial intelligence, the demand for wearable devices has surged, and flexible electronic skin is a perfect combination of wearable devices. Think about an electronic component installed on the body and used as a skin, isn't it sci-fi?Electronic skinIII Conclusion Folding computers, folding mobile phones, and wearable digital products are in the ascendant. With the development of science and technology, flexible electronic devices have received more and more attention from the society. Such devices can still work under bending, folding, twisting, compression or stretching conditions. In the future, flexible electronic equipment will have a very broad development space in the fields of energy, medical, information and communication.Pieces of work brought by flexible electronics are interpreting the integration of innovation and tradition in the era of the Internet of Everything, and the era of science and technology connecting everything is approaching.You can boldly imagine that in 20 years, your life might be like this:In the morning, the flexible electronic skin watch on your body wakes you up and reports the quality of your sleep. Put on your glasses, and the day’s schedule has been displayed for you on the transparent screen.
