I’d love to learn some of the advanced rework skills they need to work on modern motherboards - especially BGA part replacement. And how to build a workshop on the cheap! I’m always in awe at the skills they need to learn that are nonexistent in the western world.

Some repair shops have videos on YouTube. Search for a specific device or IC replacement. Some videos are oriented towards teaching vs. demo.

Here are some good "value for money" tool brands I use (I live in Asia): 1.Yihua combined hot air rework station + soldering station. 2.Pro's Kit multimeter, tweezers, and wire snips. 3.Uni-T hand-held oscillosope (quite optional). 4.Mechanic brand solder paste. Get the one in a plastic syringe. The tubs dry out. 5.TS100 soldering iron as a spare. Heats up so fast at 24V! I use them mainly for prototyping, but they are equally handy for repair. I don't re-ball BGA though. I've seen vendors do it with a machine that's mostly just a holder for the chip, and the hot air gun. Plus some templates and the solder balls.

  Thanks for the recommendations! I have a Yihua soldering station - such a solid budget option - I’ll shell out on a hot air rework station too, maybe one with a board preheater.

  > Yihua combined hot air rework station + soldering station. I personally wouldn't recommend this. I have one, it cost just short of £100. But I much prefer my T12 based 'KSGER' soldering station that was $30 from banggood and has far better features, plus I don't have to worry about the heating element dying (since with T12 the element is part of the tip). One day when I need hot air again, I'll probably think hard about finding a stand alone hot air station from banggood or aliexpress. I see they have some for $30. Since the hot-air has all the critical parts in the hand unit, and the heating and fan often die randomly, having a 2-in-1 is just too much liability. Btw, I recommend a butane soldering iron as a true 'backup' that doesn't even need a charged powertool battery.

tons of videos on youtube on how to do this
