Greeting:

I am looking for a non-destructive instrument capable measureing solder mask
via capping thickness. Thickness range is 50 - 90 % of substrate thickness
 62 mil thick ). Instrument capability shall pass GR&R requirement ( 6 sigma
< than 30% of target tolerance " 40% of 62 mil " ) and correlation to cross
section.
Anyone knows this, please share with me. Thank you.

Best regards,

C.J. Long
