my main problem always was how to transmit heat from soldering iron to something that's not solder - knowing how it should look in the end is the most trivial part of it
@zwangseinweisung flux reduces surface tension, so you can heat the solder better
it doesn't increase the contact from soldering iron to non-solder-surfaces.
(also it's really hard to even find solder wire that doesn't already come with flux inside)
@drazraeltod You're right, but I like to think that it works better when I add flux.
@drazraeltod @leyrer I usually have a bit of solder on the tip of the iron. When making contact with the surfaces, the liquid solder creates a good thermal bridge and heat flows well. I'd also not worry to much about the preheating step. Just add the solder relatively fast and keep the iron until you see the shape of the solder change to that concave desired one. It's usually pretty apparent when that happens after around 3-5 seconds.
@ponygol that's what I do too - I still suck at soldering, but I kinda got the basics after building half a dozen quadcopters now
@gom das habe ich bisher noch nicht getan (und hätte auch noch nicht passende Ausrüstung da), aber das ist eigentlich eine ziemlich interessante idee
evtl. bei einem zukünftigen Projekt — sollte ich irgendwann wieder Zeit für sowas haben
Well, but if you have some not so heat resistant parts,
maybe isolation of coax(audio) - wiring,
it's imho better to blow, if the junction is mechanical fixed. (With pliers and a steady hand)
Also recommanded is to add a tiny drop of additional flux. And dont be afraid of lead-free solder, if you get a proper mix it works totally fine.
@leyrer Ich glaub, ich druck mir das mal aus und klebs mir auf die Lötstation :)
@leyrer It's been a while for me. The last project I did was making a series of Zappers to fight parasites and bacteria. These things work.
@leyrer Who the f*** would blow on solder? 🤔
@leyrer In the early seventies, at the electronics hobbyclub, I had to learn this. By soldering a great number of pieces of wire, to a striped circuit board, evening after evening. A skill I have enjoyed the rest of my life :)
@darkstar repetition. a great teacher! <3
