Hey Russ I hate to say it but you switched from Indium for no reason! If you were getting residue then your oven profile was off! Your flux should have burned off if it was done correctly, that's the purpose of "no-clean".

Make sure that you are running the right leadfree profile. You may want to verify that it is correct with thermocouples. Use Indiums Tacflux023, This should work. As far as cleaning them after this I will have to leave up to you. Russ

I had a couple of reps in from Indium a few weeks back, and they were promoting a flux for rework that was designed to have low SIR, No clean. Havent tried it yet. The product is Flux NC 771, might solve your problem? Regards Slaine

Hi Tim, I would speak to your guys at Indium, as I am sure they have a paste developed primarily for Conformally Coated products which should alleviate your problems. John

Would anyone know the issue with caked on flux residue coming out of a 10 zone reflow oven? I appreciate anyone's feedback and suggestions, thanks in advance. We are using Indium 10.1 no clean solder paste.

Depending on the assemblies you're producing, I highly recommend 8.9HF from Indium for a low residue SAC305 alloy. We have been using this for years in our NC process and residues are very little, with appropriate stencil apertures and paste printing

Hi there. We have had troubles with pogo contamination on ICT fixtures causing false failures (Pictures attached). Currently we're spending about 10k on pogo replacement but still having problems. I recomended to clean pogos with a defluxer but Test

We are printing on an assembly using SAC305 Alloy Sn96.5 Ag 3 Cu .5 with a no clean flux and getting virtually NO spread with either a ramp to spike or straight ramp profile. We are printing to standard FR4 board with immersion Ag finish. I am trying

Good afternoon! We have had great luck with semi-aqueous cleaners from Kyzen and Zestron, and normally recommend both of them. They both have great labs and would gladly offer their input on he cleaning of the flux residue. We make sure that these

Thanks for the excellent info on testing uncured solder mask. I just checked with Chris Nash of the Indium Knowledge base and he told me that the Indium 3592 can be cleaned if need be and that I should contact Kyzen or Zestron (they are the 2 compan
