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 circuit cu imprimat impedanta controlata temperatures for gluing the components, so they are only PCB design problems.
to wires on a flat surface) that provide electrical connections on that conductive layer. Another manufacturing process adds plated or metallized holes that allow interconnections imprimat cu controlata impedanta circuit between layers. PCBs mechanically support electronic components using pads for bonding the component terminals and electrically connect them using traces of one or more
in a unique combination of superior technology a flexible printed circuit circuit imprimat impedanta cu controlata made of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits are used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or screen
