Printed circuit provides the following functions in electronic equipment
Provide integrated circuits and other electronic components are fixed, the assembly of mechanical support.Implementation of integrated circuits and other electronic components between wiring and electrical connections or electric insulation.To provide the required electrical properties, such as the characteristic impedance, etc.To provide automatic soldering resistance welding graphics for components instrumentation, inspection and maintenance to provide identification characters and graphics.
Printed circuit board according to the base material is used in rigid or flexible can be divided into two categories: for rigid PCB and flexible printed circuit board.Years has a rigid - flexible combination of PCB.According to the conductor graphic layer can be divided into single-sided PBC, double-sided PCB and multi-layer printed circuit board.The entire outer surface and the substrate surface conductor graphics in the same plane on the PCB, referred to as a flat board.
