Can static electricity damage components?

Semiconductors mostly. (chips and transistors etc.) Some are more sensitive
than others but just use common sense and you should be fine. Lots of info
on the web. This video may interest you:

When I'm doing my first DIY project, what kind of parts are sensitive
to static electricity?

If you cut the lead before you solder, how can the component stay in place?

One other question, do I need to worry about heat damaging components
that I need a heat sink of some kind?

not very often. but yes, particularly with polystyrene capacitors (they look like little plastic see-through cylinders and are very easy to destroy quickly). you can use an xcelite V80 heatsink (or just solder really quick).

you dont want long dwell times on switches. i generally avoid long dwell times on any ICs too.

Re: [motm] Can static electricity damage components?

2009-03-01 by Richard Brewster

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.

"Crimping" means forming the leads in some way. Some radial capacitors
for example have the leads cut short and formed with a small "wave"
which
helps them to be pushed into the PCB and holds them whilst soldering.
Just folding the leads through 90 deg to be flush with the board is
not really
crimping and also makes the component much harder to desolder and remove
the component to change / repair.

I've heard the term 'crimping' used to describe what I do, but I
understand your meaning. I do fold the leads 90 degrees to lie flat on
the board and then cut them before soldering. I've never found this to
be a problem for desoldering. A good quality solder wick will suck up
all the solder and leave the wire easily lifted. (Is there a good video
on desoldering, I wonder?) Then again, I've done a lot of circuit board
repair, so maybe it's not as big a deal to me as to a novice. Replacing
a resistor or capacitor is isn't that difficult, especially if you have
a Panavise (http://www.panaviseonline.com) for holding the board. The
alternative is to make a 45 degree bend in the leads, cut them and
solder. The drawback to this technique is that you have to do one
component at a time.

No, that part of the video was BS :)

You *do* need a good pair of *SHARP* cutters. There are 2 schools here.

#1: the cheap, but buy a new pair every 6 months and toss the old ones:

The Paul Schreiber, over-the-top insane cutters (stays sharp over 5 years):

http://www.all-spec.com/1/viewitem/522N/ALLSPEC/prodinfo/i=rss

The secret is do NOT cut into the solder on the board. Just flush cut the
lead sticking out of the solder.

After I built my 1st module the 120 back in 2001, I got a Panavise and have
never looked back. I don't do the 90-degree-crimp/snip/solder. I do the
60-degree-bend/solder/snip. Has worked perfect for me. Can do about a
dozen components at a time, until leads start to interfere with each other.
I also bend IC pins 60 degrees and do multiple ICs at once. I hover with
the iron less that 2 secs on a polystyrene cap leads and don't do the other
lead until after 10 secs (rotate around). Same technique for ICs.

My belief is that bending component leads to 45 or 90 degrees before
soldering is called "cinching" (to fasten tightly) and not "crimping".
