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 activity has led to a revolution in the types and models of printed circuits. Technology has penetrated more and more areas of our
Printed circuit board construction
one 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 which are almost always arranged in pairs. The number of layers and Aluminiu pe imprimat circuit the designed interconnection between them (vias, PTHs) gives a general estimate of the complexity of the
