Abstract

This publication describes a system for reading coded indices on integrated circuit boards. Laser or etching marking of circuit boards is employed in order to track circuit boards through the manufacturing process. The marks can consist of various formats. One type is using bars of two widths, the wider bars having twice the width of the narrow ones, or finding the presence or absence of a single width mark sequence. There are a number of readers for such codes available on the market today, but these are designed to read ink marks on paper, and do not work well when reading bar code written directly on circuit boards. This publication describes a reader optimized for circuit boa (Image Omitted)
