Consider your flux suppliers recommendations when determining the proper cleaning method for your boards.

We use Kester 186 flux and the STU people would sometimes find white residue after cleaning with Isopropyl at the solder station. We have Lenium (Petroferm)in our vapor degreasers, and now they use Lenium at their stations as well as final clean, an

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic ac

Dear JSK, It sounds like the root causes of your problem are two fold. First, excessive heat will polymerize the abietic acid found in rosin forming neo-abietic diamers and polymers which are much less soluble than the parent monomer. There are

Flashback time� Vapor degreasers, although still used in limited applications, no longer represent the conventional wisdom (due to multiple environmental issues). Aqueous-based technologies are the most common method of defluxing. Unlike most va

This is not a common method of defluxing. Vapor degreasers were the top choice pre-1989 but have given way to spray-in-air defluxing technology. Here come of the vapor degreaser manufacturers: Detrex http://www.detrex.com/ Baron Blakeslee http://
