Radio Shack only has paste flux in store, not the pens of the clear liquid. Can I use the thick paste to reflow? I just want to use it on something already soldered to break the surface tension and try to make sure there are no shorts by heating it again.
You can probably order a pen of fresh high-quality flux and have it shipped 2nd-day more cheaply (or close to it) than the crap they sell at Radio Shack these days. For most tasks, Kester 186 works really well and is a widely recommended brand - and sells briskly enough that you don't have to worry about it being old.
I guess I will just go on eBay and order a pen of that flux from the closest seller. Thanks!
Thanks for that. I don't do enough of this work to need that much. If by some miracle people started getting interested in the stuff I make then I might need more volume.
