text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color circuite imprimate confectionare is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help users during assembly. It is used to mark component
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 also confectionare imprimate circuite has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation, the
more and more areas of our lives imprimate circuite confectionare and required modernization, and the printed 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 greatly helped fields such as medicine and aeronautics to
