Companies that manufacture electronic components commonly laser marking for final product identification as well as identifying work-in-progress. In fact, the first widespread production use of laser engraving was to serialize silicon wafers on integrated circuit production lines.
Laser marking electronics is common for metal etching or engraving plastic packages that house microelectronic circuits. Marking speed, permanency, legibility, and the noncontaminating nature of laser engraving are all qualities that the electronics industry demand. Laser Impressions, Inc. has equipment to automatically process silicon wafers; JEDEC tray handlers for I.C. packages; and software for all SEMI standard fonts, including 2D matrix codes.
