Printed circuit board silkscreen
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 SADELEC PCB is used to render useful information on the PCB board that can help users during assembly.
Printed circuit soldermask
mask, SADELEC PCB the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of 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 also has a role of
Printed circuit board assembly
"printed circuit board" most commonly means "printed circuit assembly" (with components). 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 SADELEC PCB and some electrical products. Currently, the production and assembly of
