Printed circuit board silkscreen
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 circuit placa imprimat due to the high temperatures
Types of printed circuit board
layers are laminated together. FR-4 epoxy glass is the most common insulating substrate. Flexible-Rigid printed circuits are boards that bring in a unique combination of superior technology a flexible printed circuit made placa circuit imprimat of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate.
Printed circuit board construction
copper into separate conductive lines called tracks or circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of copper as solid circuit placa imprimat conductive areas for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar to
