Do you have any pointers concerning the oven setup and profile if you are soldering a module with bottom connections and gold pads to a pwb with an OSB finish? The solder paste is SnPb, no-clean. The paste mfgr. recommended profile produces voiding and incomplete solder coverage/wetting.

OSB ??? OSP !!!

1. The longer the soak, the fewer the Voids. 2. The Higher the soak, the fewer the Voids.

Options 1 and 2 have downsides.

You could call your paste supplier and see if they have a low-void solder paste... most likely formulated for "micro-via in pad"
