| Subject: | Soldering to a Solid Wire |
I replaced my mechanical tach with a digital one last week and needed to
connect some very small wires that came with the new tach to a couple
resistors. Decided to solder rather than crimp because of how small the
wires are. It was only halfway through that I realized I should have asked
around to see if there is a proper way of doing this. I didn't find
anything in the AEC or 43-13.
Is this good?

If youre looking for published standards, you could look at section 19 of this
document:
https://standards.nasa.gov/standard/nasa/nasa-std-87394
Its title is "WORKMANSHIP STANDARD FOR CRIMPING, INTERCONNECTING CABLES, HARNESSES,
AND WIRING"

The joints look fine. I'd only suggest that you can get by with a lot
less bare wire. Multiple ways to do it; twisting like you did (but over
maybe 1/4-1/2 inch), or by bending a couple of tiny 'fish hooks',
linking them, and then crimping them slightly to stabilize them while
you solder. Most texts make a big deal of making a strong mechanical
joint and just using solder to make the electrical connection, but
reality is that if you can keep the two wires stable while you solder,
you can just have them touching and overlapping over a 1/4-3/8" length,
the resulting joint would likely survive pulling the resistor apart,
pulling on its other lead. Making a mechanically strong joint does more
for creating a high quality soldering operation (especially for novice
'iron workers') than for joint strength.

Sebastien,
That looks pretty darned sturdy to me! I think that the resistor will
disintegrate long before the joint does.
I would have done something much shorter, adapting this technique:

Soldering looks more than fine, but focus should be on mechanical
robustness under vibration:
1. make the stiff section as short as possible
2. flexible multistrand wire on either side of this
3. cover with multiple layers of heat shrink.

Thanks Art and Alec. I really like that pm solder sleeve idea, looks great
and would have worked well here. I'll try it next time. After all, solder
costs money.
