of a reference Cablaj placat simplu indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render useful information on
a 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 it simplu placat Cablaj also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation, the soldering mask offers
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 other purposes. Each of the conductive layers is designed with copper placat simplu Cablaj tracks (similar to wires on a flat surface) that provide electrical connections on that conductive layer. Another
