My tip for a SM IC to DIL adaption.
3/8 inch wooden dowel , cut a small flat to receive the SM IC neatly.
0.2mm tinned copper wire, free end looped around first pin , around the
dowel with a bias so the wire lays tight against the up-side of the opposite
pin and wind biased spiral fashion over the top of the IC and around the
dowel. Finish with a final loop around the last pin. Clamp free end of dowel
in a vice and solder each pin to its wire. With a razor cut the wires over
the top of the IC close to the pins and cut along the centre back of the
dowel. straighten wires. Some 1mm PTFE spaghetti tubing , small length
pushed over every other wire and glued to the IC body. Fan out the wires and
solder to the pins of a turned pin socket. Continuity check for contacts and
bridges.



Wow, that's a lot of work. Why not just use a footprint adapter, e.g.
the ones from Bellin? http://www.beldynsys.com/
