Reflow, wave and hand soldering 

I find this very satisfying. After a few years in a engineering college i began to love the smell of burning metal and hot circuit boards.

Fascinating. I did most of my soldering while living in Colorado back in 1989. So this video brought back interesting memories. I had no idea that nowadays you have to be trained and certified for what I was barely trained to do back in the day. Maybe that's a good thing.

Excellent!

Very helpful
