Multilayer PCB is a printed circuit board with several layers of copper made in a standard or specific stacking, with or without a solder mask and silkscreen.
Apart from the classic printed circuit boards with metallized holes from layer 1 to the final layer, we also make multilayer pcb with blind via, buried via or filled via.
The steps that a multi-layer boards through in manufacturing are:
space between the components. The increase in the PCB Multilayer 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
0.1-0.3 mm with a rigid printed circuit on an FR4 Multilayer PCB substrate. These printed circuits are used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or screen printing that identifies components, test points or identification text. Screen printing does not normally affect the operation
layers PCB Multilayer 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 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
