One challenge was that fixing corroded vias could break connections with traces on inner layers of the multi-layer PCB. It was important to try to find out where things were going in case it was ...

Corrosion is a significant concern in the reliability ... is the use of machine learning algorithms to predict failures on PCB surfaces under corrosive conditions. A study demonstrated that ...

When [ekriirke] cracked open this gadget he was greeted with a particularly bad case, with a large chunk of the PCB traces eaten away. The corrosion was removed with oxalic acid, which dropped the ...
