solder 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, stackup imprimat circuit cu blue, white, black. Only
of copper on both sides of an insulating board), or multi-layered (outer and inner layers of circuit cu imprimat stackup copper alternating with insulating layers). Among the multi-layer PCBs, the most common are the four-layer ones. The four-layer board has many more routing options in the internal layers compared to
