PCB in this case stands for Printed Circuit Board. It is used to mechanically support and electronically connect with electronic items through conductive pathways, tracks or signal traces on cooper sheets that are further laminated on a non-conductive substrate. A PCB can more accurately be described as a Printed Wiring Board (PWB) vis-à-vis its functions.
PCB has a wide application in electronic industry; therefore has to work on a wide range of technical specifications right from materials, board thickness, trace width, space width, annular ring, pitch, plating types, solder mask, solder mask clearance, hole size etc. to name a few. From a common man’s perspective you will get a fair bit of idea about the complexity of the products once get to see your TV or PC’s motherboard.
PCB is a tech product that uses software and in many a case it needs to be customized as per the demand of the situation. Drilling method is utilized by a drilling machine that is managed by automatic computer software and links the layers of the PCB with each other by making some holes called VIAS.
Many organizations also work on custom PCBs that are made especially based on the customer’s order and specification. Here they first create a PCB model upon which they perform all their essential experiments. They initial make the design and then develop a PCB prototype. Then it is tested and again tested for examining that whether it is satisfying the needed requirements or not. Also its functionality and stability are checked properly. Only after the all experiments, it is then delivered for the making Printed Circuit Boards method.
The final step is to actually making Printed Circuit Boards. There are two typical chemicals that you can use, on is ferric chloride, available at most gadgets stores, the other is using muriatic acidity and bleach. The treatments and techniques to use the chemicals to imprint are an art and technology of their own, and that is outside the opportunity of the content. It usually includes putting the panel in the acidity and hold out for the revealed birdwatcher to get demolished in the acidity.
