Dongguan FPC flexible circuit board printing ink what is the difference

FPC flexible circuit board oil ink is mainly divided into resistance welding, three lines, three character ink.

Ink plays a role in the production of copper foil protection, so that the copper skin is not exposed, will affect the following process, sensitive ink, carbon oil, silver oil, and carbon oil and silver oil have conductivity to do, usually used ink color, white oil, green oil, black oil, blue oil, red oil, butter.

What is the difference between the inks printed on FPC flexible circuit board

FPC flexible circuit board printing ink (white oil) printing, protective oil printing (black oil), welding dry film printing (green oil)

White oil: mostly printed text and symbols on FPC flexible circuit boards, such as secondary tubes, etc.

Black oil: used to strengthen the ring strength of FPC flexible circuit board in a large area on the surface. (Also used to keep a part secret)

Green oil: used for solder joints with insulation effect, generally used on FPC flexible circuit board without adhesive place.
