Question About Soldering Technique

[tautech]

Hi,

Thank you all for the replies! I was wondering: Would it be a good idea to get some magnifying glasses? Is that commonplace among most soldering gurus out there?

YES, even if it's only some +1,2 or 3 $2 spectacles but the visor type headsets are better.
For new TH work after some experience they are of questionable need, but for any faultfinding of poor joints, cracked traces, reading component ID#'s and SMD, any magnification is welcomed but normally if your eyesight is reasonable 5X is plenty.
Start with say 2-3X for little $ and go from there as need dictates.

The general rule in avionics is either you have a lot of gold, or none.

Gold is an amazing metal, it's really useful in electronics, too bad it's so darn rare.  Need to mine asteroids to make the stuff more available for this kind of use.

Aircraft have massive vibration problems also, especially piston driven aircraft.

Vibration is a bitch to deal with.  Motorcycles can have the same problem, especially the ones with only one or two cylinder engines.

Here is the ultimate stupid question: What wire size would you use when soldering a de-9 connector? Would it be 22 awg or higher?

Thanks again!

Check the datasheet to be sure, but IIRC, 20AWG is typically the largest wire size.
