Beware the foam fluxer. I had a problem with cracked caps that just about drove me off the deep end. I discovered that my foam fluxer air knife was not turned on resulting in excessive flux. The excessive flux (VOC free) was not properly dried off

Norman- I would be pushing to get the real world to match the ideal world, in other words get your jobsetters to do the right thing. You are looking to incur more costs to justify not having to make people do their job right. A bit of training a

Vacuum casting (same process used to make solid rocket motors) should remove any air from the paste. We had thought of pressurizing the tubes to remove the residual paste, but that would entrap air. The problem of tubes sitting out for different

Larry, the best paste thinner is the one that your paste supplier recommends. You should check with him. We have no problems removing the no-clean paste with alcohol. If you want to give it a try, make sure you use IP alcohol, not alcohol based flux

Hi all, Here's the deal. I have a customer for whom I assemble a lot of product. All of their product mix goes through a water soluble process. Much of it gets conformal coated. They are in the high power arena but some products are simply contro
