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 silkscreen it also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical
better signal integrity, higher signaling frequencies, and better power supply decoupling. In multilayer boards, layers of material are laminated together in an alternating sandwich: copper, silkscreen substrate, copper, substrate, copper, etc.; each layer of copper is etched and any internal sleepers (which will not extend to
the PCB board that can help users during assembly. It is used to mark component values, part numbers, test points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight discolorations due to the high silkscreen temperatures for gluing the components, so they are
