i suspect @Aravision is more at home with welding and hitting things with BIG hammers than the fine art of precision soldering. But he could prove me wrong.
I was lucky enough to be taught how to precision solder components on PCB's, in a test equipment calibration and repair lab, as part of first job career training programme. In those days Oscilloscopes were CRT. Boy did I get some serious electric shocks working on them.
