While soldering is not that hard, different tasks require different tools. Most of them can be from very cheap to very expensive. As a beginner I'd recommend the following:

A small USB-C soldering iron supported by IronOS[1], e.g. Pinecil vor TS100

A solid stand with brass wool

A KU soldering tip (looks a bit like a knife) for good heat transfer, too small tips are not good

Thin (No clean flux (not a pen)

Isopropyl alcohol

Solder fume extractor (DIY is OK, if you're building it right) is good for your health

Solder mat (blue silicone)

Multimeter (not too cheap, around 20 bucks)

Self closing tweezers

Normal tweezers

A wirecutter (blue 5 bucks from ali express)

Manual Desoldering pump (engineer ss03 or a clone for cheaper)

Most important is cleaning (alcohol, then flux) and heat transfer (tin your tip, your pads or your wire before putting things together to ensure good heat transfer). Cleanup nicely and tin your tip after soldering to prevent corrosion.

Optional but helpful for more professional tasks:

Hot air station

Auto Desoldering pump (ZD-8965)

Adjustable power supply (fnirsi usbc, 30 bucks)

Oscilloscope (mini beginner with display Cost around 30 bucks)

Capton tape

Solid Copper wire

Oh I forgot... a big magnifier glass (8x to 15x) with an LED light is way cheaper than a microscope and very helpful for small parts soldering (SMD) :-)

You can buy a whole lot of practise kits on Amazon. Start with push-through components and move on to surface-mount if you fancy that.

I'd recommend checking out one of the many youtube channels who do repairs for an idea of the tools and stuff you need. Many have links and most use similar tools.

For $300 in tools from AliExpress you can have a pretty complete setup.

This is just a great starter list. Thank you

I have a $40 head-mounted thing with integrated light and it's awesome for modern boards.

I'll also echo the "practice kit" thing, especially for desoldering- solder stuff on, take it off, do it agin.

Also, good tools and supplies- kester solder and liquid flux.

It took me quite a while to figure out that my preferences are for desoldering braid that's been soaked with liquid flux- if I use a manual pump it's going to be rough. I am hoping to get a hot air station at some point but I haven't been doing enough work to justify it over my ancient hakko.

Nice list.

Maybe a bit over the top for a lot of situations. I assume folks would acquire these things over a long period of time depending on their projects or what they are repairing. I have a 2-ch function generator coming because after 20 years of bodging stuff together and fixing minor things, I am tired of using the super cheapo one I got back in the day. It takes a while to amass all that crap, but it's fun.

A couple other thoughts: used hemostats are super helpful for a lot of things. for a lot of years I avoided getting any kind of "3rd hand" because I would use combinations of hemostats.

Or jigs- I have a very old piece of wood that has hole drilled for m and f XLR and 1/4 audio connectors with notes about which pin is which. Making tools like that is quite satisfying.

I really enjoy having a stack of stainless steel condiment cups to put screw in- I stack them up during a disassembly and then unstack them as I reassemble.

Also I will say that while I thought building one of those cheap-o oscilloscope kits was a pretty fun practice and I can recommend that, I don't fine them easy enough to use for beginners... the 2-ch Rigol scope I got was not super expensive and felt like the cheapest thing I'd be recommending to folks.

Finally, I have had a lot of mixed successes with desoldering pumps. It took me a long time to figure out that I can only get desoldering braid to work if I put liquid flux on it, but that made it a lot cleaner for me than the solder suckers.
