penetrated 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 sita de pasta of the printed circuit board made in recent years have greatly helped fields such as medicine
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 values, part numbers, test points, polarity, etc. Screen printing does not pasta de sita influence the printed circuit and the possible
Multilayer PCBs allow for pasta de sita much higher component density because the component paths on the inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four and especially more than six layers of
