Thanks guys. I'm always getting feedback from purchasing and design that we should just put this info on the spec sheet, but I've always argued that the vendors will either ignore it, or it will become a cost driver. Thanks John S.

Some no-cleans will pool flux on the top of the solder joint which acts like an insulator. I normally do not paste "contact" pads. You can have your board house HASL them if you need the extra bump on the pad.

While it's common to use RO where TDS is sometimes very high, like Cali; it seems like the RO is killing your beds. What happens when you run without RO?

We've got away with 90C before, however at 120C they tend to bananna and it isn't easy to remove all of the product then, and some of the legs get damaged (we always received waffle packs then one day tubes arrived & the operator baked as usual....).
