A printed circuit board is generally flat and multi- layered board made of fiberglass with electrical traces. The surface and sub-layers use copper traces to provide electrical connections for chips and other components. They are widely used in electronics equipment like in mother- boards, SIMMs, an d credit card memory.Single-sided PCBs are simple printed circuit boards for power supplies, loudspeaker switches, and connectors. They are typically produced on standard 1.6-mm glass fiber epoxy laminated material for low cost, durability, and ease of production. Multi-layer PCBs are fabricated in simple 4-layer up to complex 8-layer boards. Rigid-flexible PCBs largely applicable to video cameras, cellular phones, and laptop computers. Wide ranges of PCBs are available varying in design and application. Like single and double sided, Multi-layer PCBs, RF and microwave prototype, reworking circuit boards etc. A wide range of PCBs is manufactured by a host of manufacturers.
