No Clean Flux

Vinesh Gandhi


No Clean Flux | 19 March, 1999

Hi Folks,

Need help, on white spots/marks which we are getting after wave soldering. This problem has started only once we have shifted to the no clean flux. Prior, to this we have been using aqueous cleanable flux without problems. If brushed vigorously immediately after wave soldering these get removed but otherwise after one hour or so they became permanent and difficult to remove. Please Advise.

Best Regards,

Vinesh Gandhi
