available: yellow, black, blue, red. Screen printing is used to render imprimate proiectare cablaje useful information on 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
more and more areas of our lives 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 cablaje proiectare imprimate the printed circuit board made in recent years have greatly helped fields such as medicine and
shorts, the coating is called a solder mask. Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to imprimate proiectare cablaje be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask
