I figured I should share these instructional videos from PACE. I stumbled across them a few years back. They’re pretty in depth and I’d recommend watching them, even if you have the basics of soldering down.
Basic Soldering Lessons 1 - 9
Rework & Repair Lessons 1 - 8
Note: There also available in other languages on their YouTube channel.
