Russ: On "usually get some mask material from our board house. It cures with heat so it works really well in our applications.": We're unsure about the type of mask that you are using, but be careful [we used to do this, also]: * Final cure of the L

Normally if the package is defined properly I would expect your machine to place it correctly but we have some parts pushed right down to the pads. If the paste is centered, and the parts are centered, and you have obvious bridging potential coming

It could be from your Deionized Mixed Beds. Resin on the mixed beds can have that smell if its bad or not flushed prior to use. Its a fishy/rotten eggs odor It would still happen if you dumped the water but didn't swap out the tanks and would smell

This has been our practice and its worked well: SMT process-QC/Touch-Up-Assembly. We have dedicated QC/T-Up after reflow trained under IPC requirements. They do the SMT inspection and ONLY touch-up if necessary. This way we never have to inspect SMT
