He's soldering like it's fifty years ago. Everything is lead-free surface mount now. Solder paste, stencils, reflow ovens. Hand soldering is precision temperature controlled irons, hot air rework stations, magnifiers, cameras, and exhaust fans. The tools are more complicated, more expensive, and better.

I tried soldering. With a TS100 (might have been a TS80P). I tried to solder a a Valetudo Dreame adapter [1]. Took me two hours, then I gave up. I attributed it partly to my unstable hand. Next day I tried to make a USB to (I think) TTL cable. Also failed, the cable wasn't reliable. The fumes were horrible, probably inhaled a lot. I ended up borrowing an adapter, and easily succeeded rooting the damn thing. Never again (the soldering, not the rooting). Same with cable crimping. These physical things are just not my cup of tea. I got two left hands. I hate soldering.

> Everything is lead-free Leaded solder is easier to work with for personal projects. Careful hand washing and handling is required, but it's easy. I also recommend people go to surface mount, but I don't recommend beginners immediately go for expensive microscopes and reflow ovens. Stick to 0806 components or larger to start and you can populate a board without any binocular microscope or magnification as long as yo…

Soldering is something where bad tools do genuinely make it extremely hard to do a good job. I used my dad's old soldering iron for a while, where it just plugs into the wall and gets hot, with no other temperature control than (I assume) some kind of thermal switch to stop it melting. I always hated soldering with that thing, and my joints looked awful. Then I got a pinecil, and my experience changed completely. Super cheap, heats up in seconds, does perfect soldering, and makes everything so much more fun and easy. Heavily recommend if you want to solder but are having problems with your existing iron https://pine64.com/product/pinecil-smart-mini-portable-solde...

Thanks for all the advice! For context, this poem was only partially about soldering. It's also about questions regarding ever-progressing technology on Earth, which I think some caught on to. I did use solder paste and a heat gun with a fume extractor after writing this poem. :)

I got into soldering as a child, but never learned how to do it properly. Years later I found this comic-book-style guide somewhere online, which made it quite easy to do without messing it up: https://mightyohm.com/files/soldercomic/FullSolderComic_EN.p...

Important to note that these days you really should use lead-free solder. You'll find all sorts of people going around claiming that leaded is better, but it's really not, and it's not worth the health risk. Your iron needs to be about 20c hotter than for leaded and your solder joints will look dull instead of shiny. If you find lead-free solder to not flow properly to be grainy your iron isn't hot enough.

Still wash your hands after using lead-free solder by the way. You don't want to be eating rosin or copper either.

The new breed of irons with temperature measurement built into the tip (invented by JBC, cloned by Geeboon and similar) is amazing. The tip heats to exactly the temp you want in 3 seconds, then cools down to avoid damage when you put it back in the stand. As you solder, the power is automatically controlled to keep the tip at the specified temp regardless of the load you put on it. I never thought I'd replace the Wel…

It heats to exactly the temperature I want in 3 seconds? Is there evidence to support this claim? (My bullshit detector is making some rather profound gurgling sounds.) edit: Seriously, my dudes.

Yup. They specify 3 seconds, but that's for 350C. In my experience, it's always at the right temperature by the time I finish picking it up.

It has a 240W power supply, so it's not just marketing.

I can make no claims as to the brands mentioned in the parent post, but a 3 second heating time isn't all that fast for a real nice soldering iron. Previous job had an iron that'd heat between you picking it up and moving it over to the PCB. That one was stupendously expensive from what I heard, but I can only imagine that tech has gotten a lot cheaper since then.

Try rosin flux, it smells actually pleasant!

A lot of initial soldering mistakes are from using incorrect temperature, not cleaning the surfaces with flux, or from using wrong tips.

You do get better rather quickly, especially if you ask for help!

I've got my station, not a bad one: bought it with the help of a buddy who's very good at soldering. He tried to show me. I've got no choice: I own an old vintage arcade cab from the mid 80s and it's located in the middle of nowhere, in a rural area.…

I'm not trying to convince you of anything, but if all of your soldering experience is from parts that came out of a 40 year-old arcade cabinet, don't beat yourself up: that is definitely what I would call soldering in hard mode. Depending on where it lived, everything in it is probably oxidized, corroded and covered in dust, cigarette tar, and possibly cooking oil. Even if you can't see/smell any of it, it's still t…

A glass fiber pen is my go-to for cleaning groddy pads and pins and the like. Works a treat.
