Hi! What exatly you do? Do you reflow the both sides of the board at the same time or you reflow your second side? I think in both cases you should decrease you bottom zones. If you reflow both sides - with 10-20C(F) If you reflow the second side - w

Hi Davef, The bubbles occurs at the body also...there's also a washing process before the conformal coating:-the Flux residue are removed after washing. ... The curing profile is also something that we are looking into during the initial troubles

Hi sforman1, The chemical that i'm using is a solvent based coating humiseal 1B73. From my understanding,the UV curing is mainly for UV curable coating like the UV40. And the main advantage of using UV curing is for fast throughput and environment

Hello all, I was just wondering if solder pot temperature affects the quality or the life of the solder joints? For example we run 100Sn at 275C. If I bump it up to 300C, what is that going to change?

No clean is giving us problem in ICT. Other than that, a coating of flux should remain there to pretect the solder joint from the environment. In general you should not clean NO clean - it is supposed to be there.

We just bought a new Heller 1800 EXL reflow oven for reflowing SMT boards. We us a low temp RMA solder paste with 2% silver. Everything we build is to IPC Class 3 specifications. We have approximately 600 different types of circuit boards we build
