@MarkAtMicrochip @lcamtuf "the solder isn't melting properly, better turn up the heat some more" is always the hardest habit to break for newbies

@gsuberland @MarkAtMicrochip @lcamtuf recently helped at an extracurricular "soldering for EE and related programs university freshladies and -gentledorks" workshop organized by two student clubs. 40 people who never soldered before, LED christmas tree with THT LEDs, SMD transistors and a TSOT MCU. They honestly did amazingly well.

I didn't understand how well they did until I was asked by one of them who was having trouble: their tip simply transferred maybe half the heat, and of course …

@gsuberland @MarkAtMicrochip @lcamtuf … still was oxidized enough to make it hard to have a nice solder coat.
That one was possible to improve by replacing the cracked tip with another, still worn down one. Not a fan of ERSA tips; the box with the "replacements" was full of tips where the tip, seemingly of a different alloy, separated from the body of the tip, permanently. Probably run at a far-too-high temp due to wetting issues, but still, I've never seen that before, the box had 10 of these.
