> Do I understand correctly that this process does not include a drying step? With other processes I believe you apply the liquid, dry it in an oven, and then expose it with the artwork. It sounds like the problem you are having is dealing with the wet liquid. Wonder what would happen if you let it dry first? Would it still develop under the UV?
Hi Andrew,
That's exactly right, there is no drying step. I've tried leaving it to air dry and cooking it up a bit in the toaster oven but it just stays runny until it gets some UV.
So why not leave it in the sun for a few minutes to thicken up I hear you ask. Well I may just try that, however it doesn't seem to cure evenly - some areas will go rock solid before others and if you get it wrong you've trashed the pcb as it's impossible to remove once cured.
Regards,
Bob
