Coating adhesion problems

Several things to check are: * Ask Multicore if their flux res and your conformal coat are compatible. Conformal coats and NC flux res are notorious for having compatibily issues. * Conformal coat a bare board to determine if there is there is enoug

Hi Soza: As Dave F mentioned, there are lot of factors involving the formation of residue, after cleaning. Factors, (such as: solvent's cleaning power, presence of metal oxides, type of soldering flux, etc...). One thing pretty sure, IPC is usually

We know nothing about Envivar UV 1244 and you weren't real clear about the details of the problem or the materials [eg, ws flux, solder mask, etc], but we'd speculate your adhesion problem goes back to the cleanliness of your board. First by 'alcoho

Stencil Cleaning by hand

I would advise against using IPA for stencil cleaning It may initially seem to produce good results but the way it works you end up with more problems. IPA is good at removing liquid fluxes but it dries out and cements solid fluxes to the stencils

At the OSHA training institute, our instructor stuck an electric drill in a bucket of water to demonstrate what proper grounding will do. Personally I wasn't going to try it. All our fluxes are no-clean, and are IPA based. Granted we used aqueous

We used Loctite 3609 and never had problems. If memory serves me isn't 3606 a screen print adhesive? First thing I would check is the cure profile of the adhesive. If it doesn't develop full adhesion, could be problems. Nuther question is are you

White residue after cleaning with IPA

Electronics Forum | Mon Jan 27 12:02:00 EST 2003 | Mike Konrad

Dave is correct. No-clean flux + water = white residue (unless the proper chemical is mixed with the water). Additionally, no-clean flux + IPA = white residue. Many saponifiers work well as do other cleaning agents. White residue may also be a re

Please refer the attached jpegs, The problem is noticed after reflow soldering followed by conventional through hole soldering. Flux used one is MIL Std. Brush cleaning in IPA is followed after each soldering step. regards, R.Saravanan
