have a coating that protects the copper from corrosion and reduces the chances of solder shorting between traces or unwanted electrical contact with possible prototip placa circuit imprimat 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,
printed circuit on an FR4 substrate. These printed circuits are placa circuit imprimat prototip used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or screen printing that identifies components, test points or identification text. Screen printing does not normally affect the operation of a PCBA.
of the conductive circuit imprimat prototip placa layers is designed with copper tracks (similar to wires on a flat surface) that provide electrical 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
