A Semiconductor is an element which is intermediate of conductor and an insulator. Semi-conductor is kind of material that contains electrical conductivity value between a conductor and an insulator such as copper or glass. Semi-conductors are the base of modern electronics. Semi-conductors are responsible for the computer Technology and its formation, which began in the mid of 20th century and still continuing.Semiconductor devices or electronic circuit components made from a material that is neither a good conductor nor a good insulator (called semiconductor). These devices have found wide applications because of their reliability, compactness, and very low cost. Semi-conductor systems or components are actually electronic components that take advantage of the electronic properties of the semi-conductor materials such as germanium, silicon and gallium arsenide. With the invention of the semiconductor devices have replaced most of the most of the vacuum tube applications. A semiconductor device is manufactured as either single discrete device or as integrated circuits. The integrated circuits include a few number to few million devices interconnected to a single semiconductor substrate. The cause why the semiconductor equipments are used in developing most devices is that the behavior of a semiconductor can easily be controlled by adding impurities which is or else called as doping. Transmission in a semi conductor occurs by free electrons which on the whole are called as the charge carriers.Semiconductors have massive impact on our society. Semiconductors mostly presents at the heart of microprocessor chips as well as transistors. Anything that's automated or uses radio waves depends on semiconductors. Today's mostly semiconductor chips and transistors are created with silicon. We may have heard words like "Silicon Valley" and the "silicon economy," and that's why -- silicon is the heart of any electronic device.A list of Semiconductor Components and devices includes Gunn diode, Avalanche diode, Light-emitting diode, PIN diode, IMPATT diode, DIAC, Schottky diode, Diode, Laser diode, Photocell, Tunnel diode, Solar cell, VCSEL, VECSEL and Zener diode are two terminal devices. The three terminal devices includes Darlington transistor, Bipolar transistor, Field effect transistor, IGBT, GTO, (Switched Gate Commuted Thyristor),SCR (Silicon Controlled Rectifier), SGCT, Thyristor, TRIAC, Unijunction transistor. The four terminal devices contains Hall Effect sensor (magnetic field sensor), Microprocessor, Multi-terminal devices comprises of Charge-coupled device (CCD), Read-only memory (ROM), Random Access Memory (RAM), and the list goes on.Written by  David John

LCD stands for “liquid crystal display” and technically, both LED and LCD TVs are liquid crystal displays. The basic technology is the same in that both television types have two layers of polarized glass through which the liquid crystals both block and pass light. So really, LED TVs are a subset of LCD TVs.LED, which stands for “light emitting diodes,” differs from general LCD TVs in that LCDs use fluorescent lights while LEDs use those light emitting diodes. Also, the placement of the lights on an LED TV can differ. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. The difference in lights and in lighting placement has generally meant that LED TVs can be thinner than LCDs, although this is starting to change. It has also meant that LED TVs run with greater energy efficiency and can provide a clearer, better picture than the general LCD TVs.Source: BY HOWSTUFFWORKS.COM CONTRIBUTORS   

Whether you are working on the latest device for your company or you are trying to find a replacement part for an old electronic device, finding a company to help you search for the parts you need is only half the battle. One of the difficult things to know is if your order contains exactly what you are expecting to get.  This is why knowing what kind of quality inspection process your parts supplier uses is becoming more important.These days the electronic components distributors and wholesalers are facing a difficult task especially with more and more fake, counterfeit and sub standard components making their way onto the market, this problem seem to be growing every year.The distributors and wholesalers that you use to supply your part requirements should have a tough inspection process in place to ensure you will be receiving the best quality product possible.A good quality inspection process would include several different factors including certified quality control inspectors, daily audits by lead inspectors to ensure a consistent, superior level of product inspection, a rigorous visual inspection and component tests to determine that products conform to manufacturers specifications and a quarantine and rejection process to ensure sub-standard products do not find their way into the market or into your projects.Counterfeiters today are becoming more sophisticated and making their products more difficult to recognize. A good sign that your supplier is helping the fight against counterfeit and sub-standard products is if they are a member of Independent Distributors of Electronics Association (IDEA) and use the IDEA-STD-1010-A standard. This standard was developed in 2006 by its members and is used to help educate and continue to educate its members by keeping their quality inspection processes up to date to help fight against the increase of poor or counterfeit parts. One company who is a member of IDEA and who has been in the Electronic parts and component distribution business since 1972 is Electrospec based in Dover, New Jersey.Electrospec’s quality inspection process uses the IDEA-STD-1010-A standard as a basis for their extensive quality control. They are a member of ERAI (Electronic Resellers Association, Inc.) and approved ISO 9001:2000 Certification by SGS Systems & Services Certification with their ISO quality system incorporating the relevant standards of ANSI/ESDS20.20-1999 that are applicable to an electronic components distributor.Electrospec also does all the component sourcing for PartsSearcher.com which has an extensive online parts catalogue and an online request for quote online submission form.The bottom line is don’t be afraid to ask your supplier about their quality inspection process, if it’s good enough they will not only be happy to talk to you about it they will want to boast about how good it is.
