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

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.
