Printed circuit board assembly
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 components Supply of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are assembled by their legs passing through the
Types of printed circuit board
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 on both sides of an insulating board), or multi-layered (outer and inner layers of copper alternating with insulating layers). Among the multi-layer components Supply PCBs, the most common are the
Printed circuit board silkscreen
to render useful information on the PCB board that can help users during assembly. It is used to mark component values, part numbers, test points, Supply components polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight discolorations due to
