Hi, just wondering are many assemblers using vacuum reflow systems, whether they be forced air based or vapour phase type ? If so, anyone seeing any negatives caused by the vacuum with regards liquid solder being 'sucked' away from the joints in the

I am looking into Vapor Phase with Vacuum and Inline Reflow with Vacuum (besides Heller I believe a German company SMT has something comparable). There are a couple of companies I found that make vacuum ovens for soldering of hybrid microelectronics

Agree with WiIIR and also can recommend to play with vaccum pump RPM . Slower vacuum increasing have help me to resolve one problem caused by the vacuum (it was solder splash from BGA balls, but the reason can be similar to your case). Also check i
