outer layers by gluing. provides reliable electrical connections between the component terminals in a controlled manner according to a predetermined scheme. Printed circuits are widely used in many fields: Consumer goods Military Aerospace Industrial Medical Naval The unprecedented development in recent years of all fields of cablaje proiectare imprimate activity has led to
yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help users during assembly. It is used to mark component values, part numbers, test points, proiectare imprimate cablaje polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may
on and/or between layers of conductive substrate sheets. A proiectare cablaje imprimate printed circuit board can have several layers of copper which are almost always arranged in pairs. The number of layers and the designed interconnection between them (vias, PTHs) gives a general estimate of the complexity of
