Transistors , in this case 1-amp-continuous "size" whatever the SO
designation of that is.
If I've not used hot air then a scalpel tip or needle point, as used
here,
wedged under , soldering iron melt solder a touch leting the pins relieve
themselves away from the lands , repeat wedging/desolder until fully
free.
But this time the epoxy was more structural than just for placement.
I ended up breaking up the transistor body and the epoxy stayed resolute.
Any advice for next time? if relevant red colour and more than a
micro-dot
must have been under it as traces splurged out all around the body.

"I wedged a scalpel tip (a needle point might work, too) under the device.
I
then touched a soldering iron to the pins, expecting that unsoldering them
would allow the chip to pop loose. Apparently, though, the epoxy had been
applied to keep the transistor forever in place, rather than just long
enough for the initial soldering. I ended up breaking the transistor,
while
the epoxy remained intact.

I'm biting my tongue.


Because what you really want to say is ... ??

I can only make the vaguest of guesses as to what Mr Cook was trying to
get
at.


Why are you having to guess at anything, William ? For once, I thought it
was quite clear that he was trying to remove the bloody thing from the board
to replace it with a new one. Obviously, you don't get involved too much
with surface mount reworks, as this is actually quite a common problem.
