Hello Graham, There are no simple answers to your questions but I will be giving a virtual talk covering the reasons for vacuum reflow with void data and unintended consequences in a few weeks at the SMTA joint Space Coast - Atlanta Chapter conferen

We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

when taking a reflow profile, can i attach the thermalcouple to the component body (using high temp tape) instead of to the leads (often found thermal couple dettached during reflow). in general, what is the temp diff between these 2 locatinos. if so

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

You can measure temperatures any place that you would like, but the issue is the temperature of the solder. We've seen solder temperatures that vary from lead to lead on the same component. Why don't you want to measure the temperature of your so

"If they complain just tell them it�s no different than finding the stray smt components that appear from time to time and makes me wonder why no one complains about them." Because they know, even as they're vacuuming up those stray Rs and Cs, that

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

You can, and for small parts you probably won't see much difference between body temp. and lead temp. For QFPs or PLCCs there will be a much greater delta, though. I'd be more concerned with the small surface area you're making contact on (spherica
