We run both NC and OA flux, although the majority of our product is run on OA. For application not requiring uBGA, we find the benefits of NC elusive, at best. What? .... Your customer recognizes that initially the NC res in non-ionic, but sticky.

Hello everyone, I am cosidering the possibility of using Low-Melt solder for repair purposes. However, I am concerned about adding a new alloy (agent) to the board that already has the No-Clean solder on it. Also, is the Bismuth in the Low-Melt comat

One thing I've found that will create that white residue is when moisture comes in contact with that flux. 1. Verify that you are not introducing any moisture with the compressed air supply at the foam fluxer. 2. Replace the flux and clean the flu

Kris, Weigh very carefully the above caveat with regard to IPA. I would ask for documentation to substantiate this claim, which likely stems from a desire to sell "his" chemistry, while "slamming" competition. I'll be happy to run some tests for you

Jim, I am working with O2O1's, and I have found that a combination of No clean flux with Air Reflow, reduces tombstoning, wheras, a combination of No clean flux and Air increases it. Have you or anyone else experienced this? If you have any answers

I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

| Hi, | I have a customer who's electronic assemblies produce RF. He is insisting upon aqueuos cleaning. We switched to a no clean solder years ago and no longer have an aqueous system. | Is aqueous cleaning necessary to eliminate 'cross talk' of

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 vi
