What is a MOS-FET?

MOS-FET, which is an abbreviation of Metal-Oxide-Semiconductor Field Effect Transistor, is a very important kind of transistor. Many IC's are constructed of arrays of MOS-FETS on a tiny sliver of silicon. They are very small, easy to manufacture and many MOS-FETS consume a small amount of power making them an excellent choice for many applications. It is the most common type of transistor available for either digital or analog circuits, replacing the bipolar transistor which was much more common Read more [...]

What causes oxidation on surface mount pads?

Solder contacts must meet minimum contact rating specifications to effectively be used. But sometimes you'll begin to solder an electronic component to a board and realize that oxidation has occurred. Why does this happen? Typically, there are two reasons that oxidation occurs on boards. The main reason is improper storage and handling. Boards should be received from your supplier in a vacuum pack, which would render them clean and ready to accept solder. Once the vacuum seal has been broken, Read more [...]
