Thanks, good video! The work being performed is very good as shown. Nice cleaning, fluxing, soldering, re-positioning and polishing. Fortunately, I have done very little work on ipc, although a year or so ago, a friend tasked me to repair his THF-6, replacing the power connector, which I promised to never do again after completing the job. I can still solder a 39 awg wire into most places when it is necessary (such as a micro-usb connector), however, some geriatric concerns with fine motor control make it more difficult as one ages, as you can see in this video, even.
