Learned one more awesome trick from Sorin the other day - set your lab power supply to 0 volts to use it as a voltmeter 👏.
Here's a link to his YouTube channel for more wisdom: https://www.youtube.com/@electronicsrepairschool

It's been a great week from a learning perspective - after watching this video (https://youtu.be/2b1Fm4Z577I) where Sorin says reballing is not really necessary I have indeed successfully reflowed two BGA RAM chips on two Raspberry Pi 4B boards that I was unable to fix earlier.
And today for the first time I replaced a dead WiFi BGA chip from one Pi 4 to another.
I guess practice might indeed make perfect someday 😃.
