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 of printed placat cablaj simplu imprimat circuits. Technology has penetrated more and more areas of our lives and required modernization,
different colors: green, red, blue, white, black. Only the outer layers need placat simplu imprimat cablaj to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of a fluid substance like an ink and is applied in a thin
circuit boards with more than two, four cablaj imprimat placat simplu and especially more than six layers of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are assembled by their legs passing through the board and glued to the pads on the other
