vacuum reflow

Electronics Forum | Fri May 14 05:50:26 EDT 2021 | williamrobbins

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

Vacuum Soldering

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

You can do what someone at heller mentioned to me to check if the exhaust is working properly. Take a baseball cap place it by the opening to the vent and if it wants to suck in the hat your good to go. Cost $12.00

What is the QFN or Device Voiding Levels Needed for Automotive Industry for Power Devices for Electric Vehicles?

Electronics Forum | Wed Mar 15 08:18:29 EDT 2017 | rob

It's well documented in higher power semiconductors where thermal interface materials are used, such as SIL pads, thermal grease etc. There are a couple of papers on the effects of voiding on MOSFET performance, but I haven't got around to reading
