Problem
Solutions: PCB - An abbreviation for Printed Circuit Board. A printed circuit board consists of a thin layer of copper bonded to an insulating board made of phenolic or fiberglass. When immersed in a chemical etching bath, the copper is dissolved away, except on those areas of the board that have been coated with a material that resists the action of the etchant. The copper left on the board forms the wiring of the circuit. A printed circuit is an electronic circuit that is etched, vacuum deposited, or electroplated on a flat insulating sheet. This definition was taken from the public domain program named PC-Glossary. |
