AMTech makes REL0 (4300 series) pastes that are water washable. You might want to try a sample...

We have been using the Amtech line for over 12 years now with all of our PCB and BGA Rework. The NWS-4400 is mildly active and will give better results with Lead Free Solder. Note that the LF-4300 is considered a No-Clean. However it will show lea

I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

We assemble for a customer that is having an inconsistent low level analog interference we believe with the no clean flux residue from Alphas OM5100 solder paste. We are considering testing Amtechs 4300 water washable no clean paste. We will test bot

I saw an ad for this stuff and it sounded too good to be true. Also wondering who has looked beyond the ad.

I just set that as you said, but the component doesn't stick on the board. I use AMTECh Flux type: RMA-223.. what should I do ? Thanks.

Try AMTECH 4300. Although a No Clean, it can be cleaned with only hot DI Water. A saponifer will help but the residues are easy to remove. RELO classification.
