Rather than cleaning a water soluble flux residue off the board, by encapsulating the product. covering the board or the component with lets say a Hysol encasulant. Would this prevent the active flux residue from migrating and deteriorating the elect

For what its worth. Even though you are potting the boards. If for whatever reason flux residue (OA) was left on the board prior to potting this flux could migrate and cause embrittlement problems with the solder joint. I would definately inspect for

electrochemical migration What flux are you using?

Was it determined what caused the flux migration?

my experience tells me you should have no problem. However please remove the flux residues from the board. Unless of course this is a product that is inexpensive and you don't care about degradation/flux migration etc. In example an electronic toy. T

I have seen this before. Check: --Vibration of belt --Interference (part getting "brushed off" while reflowing bottom-side components --Some glues' cross-linking mechanism is impaired by the flux during migration in reflow, redering the glue useless

Does anyone out there have any experience printing with the new synthetic pastes? The problem I am experiencing is flux migration under the screen that I do not see with my other suppliers, any help would be appreciated. Thanks,

Just went through this with a customer. Removed BGAs and noticed discolered pads at some locations. It was determined that these were open connections that had some type of flux migration between the ball. They also took solder readily. This may

If you are experiencing flux migration, try refrigerating your paste when not in use. This causes the flux viscosity to go up. I have seen flux seperate from the solder is when it is VERY old and out of date.Sometimes warmer ambient temperatures wi

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani
