Hi 'K', We manufacture both batch and inline defluxing equipment so we have no axe to grind with either technology. There are pros and cons associated with both technologies under specific conditions. Batch machines are typically good cleaners but

If I could set it up for markers and leave it I probably would not be as frustrated with the printer. We also run polyimide labels through that same printer, which means you have to adjust that sensor to a different position. Then when we switch back

Normally someone would have replied to tell you to do a search of the archives. I've read at least 4 or 5 different threads dealing with baking out PWB's, but none were for this special material. First, have you contacted the manufacturer of the PW

The use of IPA in automated defluxing systems is nearly extinct for the following reasons: 1. IPA is flammable. In a spray-in-air environment, the already low flashpoint is even lower. 2. IPA is not a great solvent. There are specific containme
