I want to apply a coat of paint over an etched PCB leaving the pads exposed. With UV curable paint a mask will prevent paint from curing under the masked/dark areas.
One would have to apply some sort of mask to prevent the paint from sticking to the the PCB. The solder paste stencil should work for this.
One would have to find a suitable masking material and a paint that worked with it. Unless the paints pull back from the masking material it will form a bridge as it drys.
I am open to suggestion on air dry paints but UV cure sounds both easier and more precise.
