Where can I buy some small wire ( about # 28 to 30 ) that has the enamel

After checking it out, it seems that it needs to be heated to almost 400
deg C and when I tried that, it did not do all that well.

I would like it to melt out with a more normal 300 deg C or so iron.

The object is to use it on a circuit board to build small projects.


It used to be sold on small spools for use in simple wire-wrap construction,
not needing fancy wire-wrap tools. I used it decades ago for a number of
computing projects, not ham radio where I tended to want wires to stay
exactly where I put them and not vary things like the inductance and
capacitance of the wiring. The simple plastic tool let you wrap a bunch of
connections, then hit them with a soldering tool to make a lot of quite
reliable connections quickly. (Not pretty, though!) So maybe searching with
phrases like "solder through wire wrap" would find you something.

That "solder through" somehow made me think "soldereze" or some spelling
like that. Maybe my memory bank is faulty, but I do recall there was a
brand name for the stuff, and that might be it.

And yes, there it was a period more or less after home computers arrived
that the stuff thrived, and probably in computer circles. Though,
Hamtronics had some famous preamplifier kits, and I seem to recall they
used insulated wire that could be stripped with heat.
