Abstract : This document describes screening procedures for the final precap visual inspection of microcircuits used in electronic system components. It is designed to aid in training personnel unfamiliar with microcircuits. The first part of this guide presents processing techniques used in industry for the manufacture of monolithic and hybrid components. Also discussed are imperfections that may be encountered during this inspection. Problem areas such as scratches, voids, adhesions, and wire bonding are illustrated by photomicrographs. This guide can serve as an effective tool in training personnel to perform precap visual inspections efficiently and reliably.
