All in all that video is pretty good. Nice pictures of bad solder
joints! He is right about cutting the leads off before soldering. I
always press leads all the way over to the board, so they are not
sticking up, but are lying flat. This is called crimping the lead to
the board. I'll crimp lots of parts, then cut all the leads, solder,
wash. They don't fall out, because they're crimped. I received some
kits from John Blacet with all resistors installed and crimped, but not
soldered. They stayed in place during shipping.
Please don't handle semiconductors on a dry winter day, while wearing a
synthetic sweater! If you keep static electricity off your body, you
don't have to worry. Humidity in the room is a good idea. I wore a
grounded wrist strap when soldering was my day job. I have one, but I
rarely use it.
You don't need a heat sink clamp on transistor leads, if you solder
correctly and limit your dwell time to 1 or 2 seconds. One thing I do
is solder one transistor lead, then solder some other components and
come back to the other transistor leads a little later, giving the
transistor time to cool down between soldering each lead.
