Components are generally soldered to the PCB both to connect them electrically and to fix them mechanically. Printed circuit boards are used in almost all electronic products and some electrical products. Currently, zi Camera de the production and assembly of printed circuits are automated. Electronic computer aided design
and/or between layers of conductive substrate sheets. A printed circuit board can have several layers of copper which are almost always arranged in pairs. The number of layers and the designed de Camera zi interconnection between them (vias, PTHs) gives a general estimate of the complexity of the board.
Screen printing is used de zi Camera 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 influence the printed circuit and the possible problems that may appear may be
