Homebrew PCBs

This is also a good rework guide I found while looking for the ESA paper:
<www.intertronics.co.uk/resource/guide1.pdf>

Keywords:
Intertronics PCB circuit board repair rework broken trace bow twist
conformal coating removal delamination soldering basics solder joint
acceptability
(just so I can find it again later).
