Has anyone here specially the Gurus heard, used or seen a Reflow Oven with Vacuum? Is the result really good when it comes to reducing Voids? Can you share any info about this oven? thanks and regards...

Vacuum Soldering is mostly available with Vapor Phase Soldering systems as a option.

Asscon / IBL / Rehm Thermal all offer this...

Rehms system is unique as they offer in place solder and vacuum vs the other two vendors that move a PCB with Molten Solder into a seperate Vac Chamber. Rehms system also has many other process benefits over other Vapor Phase methods...

Vacuum does reduce or remove voids, can also control wetting to a degree. Of course too much Vacuum is not good either so system needs to have good control for user and process tuning.

We have been doing pilot runs with vacuum installed on vapor phase. Voids are down but bridges are up on the .5mil BGAs.
