Printed circuit board construction
is designed with copper tracks (similar to wires on a flat surface) that provide electrical Capability Manufacturing PCB connections on that conductive layer. Another manufacturing process adds plated or metallized holes that allow interconnections between layers. PCBs mechanically support electronic components using pads for bonding the component terminals and electrically connect them using traces of one or more
Printed circuit soldermask
shorting between traces or unwanted electrical contact with possible loose wires. For its function of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can PCB Manufacturing Capability have different colors: green, red, blue, white, black. Only the
Properties of the printed circuit board
It is recommended that the power and force paths be larger than the signal paths. In a multi-layer board, an PCB Capability Manufacturing internal layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave printed circuits, transmission lines can be laid out in a planar form, such as stripline
