Printed circuit soldermask
a PCB can have a coating that protects the copper from corrosion and reduces the chances of solder shorting between traces or unwanted electrical contact with possible loose wires. For its function of helping to prevent solder PCB Capability Manufacturing shorts, the coating is called a solder mask. Soldermask is generally green in
Printed circuit board construction
holes that allow interconnections between layers. PCBs mechanically support electronic components PCB Manufacturing Capability using pads for bonding the component terminals and electrically connect them using traces of one or more layers of copper sheets laminated on and/or between layers of conductive substrate sheets. A printed circuit board
Types of printed circuit board
copper on both sides, which are called outer layers; Multilayer sandwich boards with additional internal layers of copper and insulation are called multilayer. PCBs can be single-sided (one layer of copper), double-sided (two layers of copper on both sides of an insulating Capability PCB Manufacturing board), or multi-layered
