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:
circuit with controlled impedance, the impedance will be controlled by Multilayer PCB acting on the dimensions of the tracks and the distance between them, i.e. the insulation. For a multilayer printed circuit with a specific stack-up, it must be taken into account that the internal tracks with controlled impedance are shielded by copper planes and for
is applied in a thin layer similar to varnish on the entire surface Multilayer PCB 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, the soldering mask
