boards, layers of material are laminated together in an alternating sandwich: copper, substrate, copper, substrate, copper, etc.; each layer of copper is etched and any internal sleepers (which will not extend to both outer surfaces of the finished multilayer board) are plated before strat un circuit imprimat the 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 activity has led to a revolution in the types and models
high frequencies, great care must be taken in designing the imprimat strat un circuit tracks to match the impedance of the upstream and downstream components. The longer the route or the higher the frequency, the better adaptation is required. When producing the printed circuit with controlled impedance, the impedance
