Homebrew PCBs

Hi Dave-

I gather the other popular wire wrap wire is teflon insulated; one
common brand name is "Kynar", and you are right, the insulation is
actually resistant to melting, as the web page you included points out.

If you find a ready source of the polyurethane coated wire I'd be
interested, since the melt-insulation-solder-wire procedure is great
for those traces you need to add after the PCB has been etched <g>.
That's what I am using the RS wire wrap wire for but it won't last
forever.

Here's the stuff I am talking about-

RS 278-502

See:

Seems that does have kynar insulation, but it melted ok on my last
patch up. But it seems like you need the PUE insulated type. Oh well.
