substance romania pcb like an ink and is applied in a thin layer similar to varnish on the entire surface of the printed circuit less on the soldering pads and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation,
inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, pcb romania four and especially more than six layers of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are
circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of copper as solid conductive areas for electromagnetic shielding or romania pcb other purposes. Each of the conductive layers is designed with copper tracks (similar to wires on a flat surface) that provide electrical connections on that conductive layer. Another manufacturing process adds
