i am going to try it to use with Electrolube HPA. BTW we ran into a similar ptoblem, we just put pink mask on it to seal it off. still takes less time than to mask them with tape

Ammonia based masks can create solderability issues after they are removed. You can get non-ammonia based latex mask material but down side is slower cure and cost a little more as they have higher levels of latex etc

I have a need to dispense a latex masking material using an automated dispensing system. We are presently looking at the I&J750. Does anyone have any experience with this piece of equipment, or have a better solution available?

Does anyone knows where I can buy these rubber cones? They work as masking - preventing the solder to adhere to through holes(rings) while wave soldering

Did the board fabricator forget to apply the nickel undercoat?

It's happened perviously. If that happens, there is a widespread solderabily issue, not just on selected pads.

A while ago I tried using rubber boots for masking but couldn't get them to work because the coating we use (Humiseal 1B73) is so thin it leaches under the rubber. If you can get them to work with your application more power to ya.

We do a conformal coating for a customer with copper-nickel-gold pads on his board. The pads are masked prior to coating with a standard gel, containing ammonia. After thousands of boards, being processed like this, now the gold pads seem to be less

Caplugs Very low tech, and very low cost. you will have to do a bit of work to find a size that will work for you, but the savings are worth it.
