Is there a JEDEC, EIA or Military standard about optical inspection criteria for chip scale packages?

See if JESD22-B101 addresses it.

Thanks Al, I could sure use this document. But it is not as comprehensive as I thought it would be. I was mainly looking for a standard tolerance of edge chipping on the backside of a chip scale package (i.e. 5 or 10 mils wide or deep for 2mm x 2mm package). One of our customer document referred to "PS 5207 Worldwide Second Optical (Visual I) Inspection Criteria for Mospower Designs & Standard Devices". Maybe I'm not looking hard enough coz I can't find it in the web. Are you familiar with this standard?

If they are imposing it, they should be able to help you.

Carl, look at MIL-STD-883 method 2009.9, external visual inspection for hybrid microcircuits.

Hi Al...I read the standard you attached but it is for a hermetically sealed device which we don't process in our factory...I still downloaded though for future reference.
Also, our customer who referenced the spec that I mentioned is no longer an active customer so I don't think it would be appropriate if I ask them about it now.
Anyway, thanks a lot for your help and if ever you still have standards to share I would very much appreciate it.
