Yes. Dr. Garland and Dr. Walker have told me that they
"decapitated" them both mechanically (with a very sharp
chisel) and with heat (using a precise lab bench heat
plate). I'm trying to decide which way to go myself.
I only have a few to "screw up". I have a fairly high
quality Pace SensaTemp soldering iron that can reach the
required temperature (291 degrees C, I'm told). I have
a large "mini-wave" tip that will hold a large drop of
solder. I'm probably going to try that first. Lightly
grip the chip in a small bench vice, mostly inverted.
Bring the soldering tip up from underneath and apply heat
until the cap shows motion, quickly remove the heat and
push the lid off with a piece of wire.
