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 imprimate circuite of our lives and required modernization, and the printed circuit through its continuous improvement
products and some electrical products. Currently, the production and assembly of printed circuits are automated. Electronic computer aided design software is available to do much of the layout work. Multilayer circuite imprimate PCBs allow for much higher component density because the component paths on the inner layers would occupy the space between the components. The
board. It has copper on both sides, which are called outer layers; Multilayer sandwich boards with additional internal layers of copper and insulation are called multilayer. PCBs can be single-sided (one layer of copper), double-sided (two layers of copper circuite imprimate on both sides of an insulating board), or
