Abstract
A method is provided for laser optically marking integrated circuit (IC) packages in a non-destructive manner. The method provides an IC die encapsulated as a package in a compound of glass spheres and epoxy. An acute angle is defined between a laser optical path and an IC package planar surface. The IC package surface is scanned with a laser, and in response to ablating the IC package surface, a legible mark on the planar surface.
