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 is used to render useful information on the PCB board that can help users during assembly. It is circuit cu imprimat metalizate gauri used to mark component values,
Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder metalizate gauri imprimat cu circuit mask, 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
