Printed circuit soldermask
Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of components Supply a fluid substance
Types of printed circuit board
is the most common insulating substrate. Flexible-Rigid printed circuits components Supply are boards that bring in a unique combination of superior technology a flexible printed circuit made of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits are
Printed circuit board assembly
occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four 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 components Supply to the
