Printed circuit board construction
lines called tracks or circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of copper pcb as solid conductive areas for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar to wires on a flat surface) that provide electrical connections on
Printed circuit soldermask
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. pcb For its function of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally
Printed circuit board silkscreen
with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help users during assembly. It is pcb used to mark component values, part numbers, test points, polarity, etc. Screen
