Hi folks, I am Les Bogert an engineer from Bechtel
and am seeking some Test 101 education. Specifically, are there any PWA
test methods out there (e.g. bed-of-nails, boundry scan, flying probe, etc.)
that can be used to: 1) determine if polarized capacitors are installed in
reverse - A method that will not damage the part from reverse voltage; and 2)
method to test if one bypass capacitor is missing when there are many tied in
paralled on the same PWA. I know this can be done using automated
optical inspection but the cost is out of the range of what we are willing
to spend. Any help would be appreciated.
Thanks
