PCB Rework and Repair Guide [pdf]

Almost 30 years old. Old good times without BGAs and modern barely visible components. While some basics are still applicable the modern problems are not covered at all.

I don't think that modern boards are really repairable at all beyond component replacement- 4+ layer stackups being the big reason. If there's a way to do anything to those boards besides total replacement I'd be super interested to know.

The techniques here are also way beyond basics I think- like, you look at most guides for repair and it's "idk just solder some bodge wires on there, here's what a good joint should look like"

		Andrew Zonenberg posted a Twitter thread a year or two ago where he fixed a missing PCB trace some layers down a PCB, with a stereo microscope, precision mill and very steady hands. Edit: here's the thread. It's a 6 layer PCB with a short on L5 that needs to be fixed from the L1 side. https://xcancel.com/azonenberg/status/1468825231225540611#m

It's great for working on vintage equipment, stuff that might need (and warrant) that kind of repair. Less so if you run a cell phone repair shop.

Missing: how to solder a wire to the thermal pad on the bottom side of an IC. Assume there are components on the back side.

Watch the PACE videos as well, they’re on YouTube and they also cover how to remove conformal coating and using different tools.
