That's my Typo... couldn't figure out how to fix it. It should read SMT -boards with lots of SMT parts, including PBGA. I'll be more specific next time.... Thanks for the replies.. Carol

That would be the elusive typo, check your keyboard, the "A" is right next to the "S". I believe she meant "SMT" boards. Wazzup Dave, your grey matter already shifted into weekend mode? Hoist a pint of Sierra Nevada, if you get that spill in your ne

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon
