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

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

Hi, are there any component types that are not suitable for vacuum reflow ? I've had one customer use his vacuum vapour phase reflow system on a pcb, and on 10% of the hermetically sealed accelerometers devices. the lids have popped off... Thanks Gra

I've only used vacuum reflow on LED boards but I have heard that Vacuum may need to be reduced depending on components. I can't find the source at the moment but it was a study done by Heller I believe. I would experiment with different levels of v
