Any opinion/spec/study on acceptability based on size and location of void in chip cap/res (e.g 0402) solder joints?

Assuming that you are talking about voids in solder connections: * Consider voids on the surface of your solder connection a defect. * Consider voids that you can't see to be a process indicator.

See A-610C, 12.4.8 for authoritative guidance.

Oh, and turn off the GD x-ray machine er you'll drive yourself beezerk.
