What is Printed Circuit Board? Printed Circuit Board also in short known as PCB serves as the base for almost all the electronics for both - wiring area & the physical support piece. The material used for making PCBS are mainly fiberglass, composite epoxy, or any other material which is composite by nature. PCB is the interconnection between the electrical & electronic components which can be easily found in radios, radar, beepers, pagers & computer systems. PCB assembly is mainly constructed in three different ways- singled sided, double sided & multi-layered. With the help of two methods the components on a PCB are electrically connected- surface mount & hole technology respectively. To elaborate surface mount technology, it can be explained that the L-shaped or J-shaped terminals of each of the component gets in contact with the PCB. And in the hole technology, each component has thin leads, theses leads are pressed with the help of tiny holes ...
