For chrissakes, everyone *knows* not to use acid-core solder for wiring
connections. The fact that we're even talking about it here is totally
ridiculous.
But don't take my word for it:
http://www.scienceprog.com/reliable-...ng-with-fluxes
They say "You should never use acid fluxes in electronic device
soldering and repair, as it will cause corrosion and even can
short-circuit device where gaps between tracks are small."
Sheesh.
I never said acid - that's you jumping to conclusions and getting it
wrong.
You said, and I quote:
I keep a tub of active plumbers flux ready to hand.
That stuff is acid flux. Wrong flux for wiring.
He means for ****ty 20 year old automotive or marine wire thats got so
much corrosion on it you can't brush it up. I've seen wire like this
plenty of times and rosin core flux won't touch it. I usually use cripms
on this kind of job, but acid flux also works.
Actually I doubt the plumbers flux I use is acid.
So you actually don't know what is or isn't in it. (I don't either.)
Might be worthwhile rooting around to try to find its contents (either
online, in a MSDS or from a supplier). My guess is that it is, in fact,
an acid flux.
UK building regulations are also affected by the dreaded RoHS so
things like corrosive fluxes aren't allowed any more. It was some
years ago that building suppliers stopped stocking Fry Fluxite (zinc
chloride) I still find uses for this flux in certain jobs and finally
found a power tool supplier that could order it..
I think you misunderstand RoHS and other regs; they don't seek to ban
anything corrosive, just regulate substances that are hazardous. I
seriously doubt that acid fluxes have been banned outright, or that they
ever will.

Personally, I like Vista, but I probably won't use it. I like it
because it generates considerable business for me in consulting and
upgrades. As long as there is hardware and software out there that
doesn't work, I stay in business. Incidentally, my company motto is
"If this stuff worked, you wouldn't need me".
