I'm looking for an acid based solder paste for electrical soldering.
I haven't purchased the stuff for years. Things have changed quite a
bit. We used to refer to it as an RMA type. There seem to be so many
kinds now,; no lead, no clean. It needs to reduce aggressively.

For electrical soldering you went Rosin Core solder. Acid flux is NOT
for electrical use. Just buy the solder with the rosin core. I dont
think rosin is sold separately.

Acid paste and acid core solder is for soldering plumbing, gutters,
sheet metal, etc. (It should be cleaned off after the soldering is
finished too, and you can not clean it off too well on electrical
components. It will corrode the components and copper wire.
