I need to troubleshoot this series of old PC card where 1/3rd have been failing after several years of service. The age of the board makes me suspect the passive components are well past their prime. Particularly, there are about 15 tantalum capacitors on the board that are mostly rigged up as bypasses.
I'm thinking of renting one of those capacitor ESR meters that can test the capacitor in-circuit. On the off chance I end up keeping the ESR meter, I'd like to know how the failure modes of tantalum capacitors compare to other capacitor types.
Questions:
* Are these ESR meters pretty good at spotting tantalum capacitor problems?
* Can they detect problems in ceramic or electrolytic capacitors just as well?
* Anyone know of a good ESR meter schematic?
