About Silk Screen Process in PCB Manufacturing

About Silk Screen Process in PCB manufacturing:

Main equipment for Silk Screen Process in PCB manufacturing: screen printing machine. Oven. UV dryer. Screen plate making equipment through the screen printing principle to transfer ink to the product. Main printing product batch number, production cycle, text, black shade, simple line and other content. By positioning PIN will Product and screen positioning, the ink is squeezed onto the product by the blade pressure. The screen is part of the text and pattern.

Separately, no text or pattern part is sealed by the emulsion to prevent the ink from leaking. After printing, it is dried in the oven, and the printed layer of text or pattern is closely integrated on the surface of the product. Some special products require some special lines, such as single Adding a few lines to the panel to achieve the dual panel function, or adding a layer of masking to the double panel must be achieved by printing. If the ink is a UV drying ink, it must be dried using a UV dryer. Common problems: missing, contaminated, gapped , protrusions, shedding, etc.
