We are having a heck of a time inspecting some solder joints and could
use your help.

Per Class 3 a solder joint is supposed to have at least a 75% fill. We
have a circuit board that has large ground planes and hand soldered
connectors that are impossible to inspect for top side solder.

We do not have access to an x-ray and are wondering if there are any
clever ways to inspect these solder joints.

Thanks,

KennyB
