Checked the archives with no luck. Anyone have a reliable test method of verifying acrylic conformal coat cure. Using Humiseal 1B31 mixed with approximately 30% solvent, spraying with a Nordson. Thanks in advance.

Hi Charlie, It looks like its displaying your display name on the listing but your username when you post. You're the only person that sees that. We've logged the bug though and will address it in our next bug sweep though. Thanks! Brian

We are seeing a white, powdery residue following the Wave process. Is this a solder masking issue (poor cure from the PCB mfg) or Wave process related? Any input is greatly appreciated.

This happens to be after the water wash process. These are Burn-In boards so an SMT epoxy is used prior to wave. The flux used is Kester 2331ZX. Would using a thinner cause this to occur? The residue is all over the board. Thanks.

If the thinner you are using is 4662 and the correct amounts that should not be the problem. Is this the first solder operation? I would start by looking for rosen or no clean flux getting on the boards at some point before wave soldering and not bei

I had confused by same problem, the reason I found is the interval between wave soldering and cleaning is too long and did not set the temp. of D.I water at 120F~150F. Kester flux is good. Rgs, Wister

I have experience to the Kester 2331 water soluble flux long time ago with white residue and it related to the solder masking. Check what kind of the solder mask and ask Kester to do the test for you. Rgds.

Considering putting one of these into production. Any comments as to reliability, accuracy, programming ease, etc. greatly appreciated. Targeting small discretes (e.g. 0402), PBGA, CSP, & QFP (to 16 mil) Thanks in advance...
