ZAP!--OH ****!

Har! Did he kill it?

We had to assume so, since to test it we would have had to solder it
on the board along with all the other expensive parts, and didn't have
the hot air rework station to properly remove them. The board was a
special low-loss material for 1GHz controlled-impedance circuits,
with unknown desoldering properties, similar to the material used in
oscilloscope inputs.
