Hello everybody, What is considered "high frequency" when we talk about possible issues with NO-clean flux residues and product's application? I appreciate your help on this... Have a good one! George

I don't believe you'll get an exact zero flux with no-clean pastes. Water soluable yes, but I don't see it happening with no-clean; at least not this year. As for spatter, you should be able to control this. Can you define what you call "spatter"?

We have customers that are requiring no flux residue left on boards after soldering of non-water washable parts. We currently use Multicore Crystal 502 No-Clean to solder parts that are not washable. Has anyone come up with a good way to remove this

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with

Wasn't aware of that. We're using a no-clean with RF pcbs, and that's something to bear in mind for the future - thanks.

DO NOT Mix Technologies.... If you are using a no clean solder paste use a no clean wave solder process. I have direct experience with using a no clean paste and a RA water-soluble wave solder process. When cleaning with the water wash system your
