Although John's lbw's (little blue wires / silver plated hard core copper
teflon coated wire-wrap wire...) does "work" there is
sometimes a more elegant solution from Tektronix.
They sell something like a "flexible print with connector"
for soldering the flexible print directly to your print or
IC and connecting the connector to your probes.
