Printed Circuit Board (PCB) Designing

A PCB (printed circuit board) is an electrical circuit whose components and conductors are contained within a mechanical structure. PCBs are most commonly manufactured by fibber glass, composite epoxy and other composite materials. Conductive features include copper traces, pads, heat sinks, or conductive planes. The mechanical structure is made with insulating material laminated between layers of conductive material. The overall structure is plated and covered with nonconductive solder mask and silk screen to legend electronic component location.
PCBs are used in a variety of industries like Automotive and aerospace, Lighting, Industrial Application and Medical Industries etc
