PCB (printed circuit board) supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components are generally soldered on the PCB.

        Printed circuit board materials

The base PCB material (CCL-Copper Clad Laminate) is a composite material that composed of dielectric layer (Resin, glass fiber) and high-purity conductor (copper foil).
