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- board, simms, and credit card memory. Single-sided pcbs are simple printed circuit boards for power supply, loudspeaker switch, and connector. 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 camera, cellular phone, and laptop computer. 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.
