Properties of the printed circuit board
is recommended that the power and force paths be larger than the signal paths. In a multi-layer board, an internal layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave printed Capability Manufacturing PCB circuits, transmission lines can be
Printed circuit soldermask
the chances of solder Capability PCB Manufacturing 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 have different colors: green, red, blue, white, black. Only the outer layers
Printed circuit board silkscreen
is done on Capability Manufacturing PCB the top layer of the PCB and has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue,
