them, i.e. the insulation. For a multilayer printed circuit with a specific stack-up, it must be taken into account that cablaj imprimat the internal tracks with controlled impedance are shielded by copper planes and for this reason only the thickness of the insulation between layers and tracks and the
allow interconnections between layers. PCBs mechanically support electronic components using pads for bonding the component terminals and electrically connect them using traces of one imprimat cablaj or more layers of copper sheets laminated on and/or between layers of conductive substrate sheets. A printed circuit board can have several layers of copper
protects the imprimat cablaj copper from corrosion and reduces the chances of 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
