chances of solder shorting between traces or unwanted electrical contact with possible loose wires. For its function circuite imprimate of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the
activity has led to a revolution in the types and models of printed circuits. Technology has penetrated more and more areas of our lives and required modernization, and the printed circuit through its continuous imprimate circuite improvement was one of the first aids that allowed this modernization. The smaller and smaller
inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four and imprimate circuite especially more than six layers of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are assembled by
