Subject: De-fluxers for rework

 

What are y'all using for de-fluxing rework? I was using EC7m, but the price skyrocketed, presumably because of the R134a propellant it uses. I'd be happy to get it in a can or bottle (unpressurized) and just use air brushes or other techniques to dispense it.

 

In the past I've also used Axarel 2200, and found that to work pretty well, especially if soaked in an agitated bath of it. But I'm just running a small research lab at this point, and the minimum quantity is 15kg, which is probably enough for about 10 years.

 

Isopropanol is pretty awful, and I find FluxOff to be even less effective.

 

Thanks,
