Jim,
I would suggest, and we offer a 3-way approach:
acoustics
elevated T/H
microsections

Subject: [TN] Detection of potential cracked capacitors and resistors
Looking for a quick/easy way (if this is even possible), to verify if
ceramic capacitors and/or resistors placed on a PCA are cracked.
Can an X-ray be used to check for cracked capacitors and resistors?
We had an issue with hand soldering of other components that compromised
the PCA and could possibly lead to cracked components. If X-ray cannot
detect the cracks, are they other methods of inspecting for cracked
components that you guys can think of? Besides electrical test (PCA's will
not fit in electrical test fixture now due to hand mounted components).
Thanks,
Jim
