>Steady hands aren’t a requirement unless you’re doing very complex repairs

I remember I was in college when I tried to solder some jump points on my xbox to enable me to mod it. I went in expecting electronics to look like what they did when I was growing up (I used to take everything apart, but I usually was able to put it back together). I open it up to find the jump points are smaller than grains of sand. It left me very much wanting some sort of mechanical aide to help. I occasionally watch videos of people repairing gpus or mbs and I cannot imagine how they do it.
