Abstract

Pulsed CO₂ TEA lasers are widely used in the electronics and semiconductor industries to mark passive components, hybrids and semiconductors. In addition to marking simple product identifying codes, an increasing requirement is to have the laser system mark variable information, derived from test results, on these products. This has required the development of laser beam delivery systems of increasing sophistication, capable of marking both alphanumerics and machine readable bar-codes, that are interfaced to test and process control equipment to permit high-speed, variable information coding.
