Hi Bob, It's funny you should mention that. We're looking at building a board that contains these little devices from Avago that says to clean with with Acetone and rinse with Alcohol: http://www.avagotech.com/docs/AV02-2001EN I've never had to do that before. Hmmmmm....

The assemblies we make for them are cleaned using a closed loop aqueous board washer then sampled for cleanliness with our zero-ion tester per J-std-001E guidelines. Recently this customer commented that boards appeared dirty upon cleaning with the acetone. Does anyone have any thoughts on this acetone cleaning process.
