[sdiy] [OT] Soldering pins on QFP, etc

[Roman Sowa]

Yor sanity disclaimer at the beginning of your message does not alow me 
to tell you that soldering individual pins is not the way to go. I will 
also not tell you that you can use ANY tip to solder those, even a big 
nail heated with lighter. Just as long as you use solder thin enough and 
proper flux. And you probably don't care if I tell you that I solder 
0.5mm pitch chips with chisel tips, from 1 to 5mm wide, and sometimes 
few other tips specifically designed for that job.

So if you want specific fine tip soldering iron only for soldering TQFP 
pins one by one, get cheap $26 iron from Ali, can't remember the name of 
it, 3 letters with probably "Q" in there and maybe "X". It even has one 
sharp tip in the set. It's surprisingly good.

And if you don't want to replace tips, that's maybe because your iron is 
not designed for quick tip change. There are a lot of brands today 
making stations with tip change procedure that lasts 3 seconds, and 
actual heating up from room temperature takes from 5 to 20 seconds. That 
makes you enjoy replacing tips even if it's not necessary.
