PCB Solder Mask Ink in Various Colors
Does PCB solder mask colour have any effect on the PCB?
In fact, PCB ink has no effect on the finished PCB. But for semi-finished PCB has a great impact, such as green in matte green, sun green, dark green, light green, etc., the colour has a little difference, the colour is too light, it is easy to see the appearance of the board after plugging holes in the process does not look good, the colour is too dark, the ink used by some circuit board factories is not of sufficiently good quality, the resin and the dyestuff ratio is problematic, bubbles and so on, and the serious in the final curing session will drop ink! The ink will fall off in the final curing process.
