models of printed circuits. Technology has penetrated more and more areas of our lives and required modernization, and the printed imprimat circuit aurit circuit through its continuous improvement was one of the first aids that allowed this modernization. The smaller and smaller dimensions and the flexibility of the printed circuit board made in recent years have
flexible printed circuit made of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits imprimat aurit circuit 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.
of copper foil, laminated to the substrate. Chemical etching divides the 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 conductive areas for electromagnetic shielding or circuit imprimat aurit other purposes.
