The present system, which uses a recirculated bath of water alone with no rinse cycle, does not fully remove the lubricant
Removal of lubricant which might be source of blisters in wire
have FTIR, would like to evaluate contact angle and OSEE. Assume 20 kHz for ultrasonics and <5 sec cleaning time.
Four aqueous based products were found to be successful in removing the drawing compound using ultrasonics at 25 kHz. Contact angle and OSEE proved to be useful analytical methods for this process.
