Are these molten solder bubbles, or another substance "foaming" up on the surface?

Hi, I think they are a bit of both. When they pop the bubbles something like a foam is generated.

In a previous lifetime, we had a selective solder machine where I would see solder splashes in the roof of it. I thought someone might have been putting the solder extremely high. But when it was melting there would be bubbles that burst. The manufac

In this case nitrogen is not used but thanks for your contribution!

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

Hello colleagues, I appeal to your expertise in this matter that has taken me by surprise. A week ago it was decided to change the solder brand for the wave machine, (only the brand, the alloy is the same). The pot was emptied and filled with the

I have found that depressurizing the tanks when the machine is not in use reduces bubbles.

Update on 1B73 bubbles, Changed over to a mixture of Humiseal 73 thinner with coating (25 sec on Zahn 2) observed a reduction in bubble formation (approx. 20%) but still present.

We've got a problem here, where we're hand spraying a urethane conformal coat on over a rectangular inductor. The inductor body is a plastic tube, with potting to fill. The top is not always flat (sometimes concave). The problem is that bubbles appea
