Good morning Tim, I'm e-mailing you a data sheet for the Ionox BC cleaning chemistry for disturbution. If you have any other questions please feel free to call me at 603-622-2900 x111. Thank you.. >>> Tezak Tim <[log in to unmask]> 08/12/97 02:56pm >>> Lainie - We use an alcohol type solvent from Kyzen. The product is called Ionox BC. At ACT we soak the PCB assemblies (with flux) in Ionox BC for 20-30 minutes. After soaking for 20-30 minutes, the PCB asseblies are cleaned in a Westek Triton high pressure in-line D.I. water cleaner. We use this procedure to remove hard to clean white residues (both No Clean and Water Soluable fluxes) and solder balls associated with the No Clean processes in general (reflow/wave). This should also work for cleaning baked on fluxes. For info on Kyzen products contact Eric Bromley at Kyzen.

Alcohol is not working very well and scraping is slow and tedious. Thanks! P.S. The flux is aqueous (Kester 1189). Lainie Loveless General Atronics Corp Wyndmoor, PA (215) 242-7336
