Bob,

        I have had good results with Teflon and I-PVC insulated wires in a
reflow application.  We even wave soldered a few applications. (sub-merged)

        Through testing I found we could a use pin-in-paste method and the
insulation held up well.  If you are doing a Pb-free reflow, there may be
issues, as the temps are higher than SnPb.

        Do some testing, with TC's attached to the wires.  You may be
surprised to see the results.

Good Luck,

Rich

        Subject:  [TN] Soldering wires to PWB with SMT Reflow process

        To All,
        We have a application where it would be very nice to solder two
small wires
        to a PWB assembly while we are reflow soldering the other SMT parts
to the
        board. So far we have not found a wire type that a manufacturer will
ensure
        will survive the reflow temperatures. Solid wire with insulation is
needed
        in the 22-24 awg. size. Does anybody have experience soldering wires
to
        assemblies in reflow processes?
        Any leads would be appreciated.
        Thanks,
        Bob Donaldson
