Abstract

Disclosed is a feature that simplifies the inspection of chemically milled parts for dimensional accuracy. The feature is part of the artwork that, when strategically located, is used to accept or reject large panels of etched parts. It is used as a go, no-go criteria rather than measuring components with time-consuming optical techniques.
