I am starting to use BGAs more and more in our process, which is using water soluble paste. Taking to the Paste Rep, he had pointed out that if you add Surfactant Packs to your inline water wash, that it would help get the water underneath the BGA pa

Michelle, Our experience with no-clean solder pastes has been that water washing a mis-print is a bad idea. We've found that DI water does not do a sufficient job removing the no-clean paste (the same goes for stencils). Instead, we have washed no

The use of IPA in automated defluxing systems is nearly extinct for the following reasons: 1. IPA is flammable. In a spray-in-air environment, the already low flashpoint is even lower. 2. IPA is not a great solvent. There are specific containme

Without get too deep. The biggest drawback of batch washer, you can't pack too many boards into same batch. If you are washer very larger boards, that's the bottleneck. If you are washing No-Clean board, then you wait even much longer, more than dou
