An Algorithm for Correction of Distortion of Laser Marking Systems

Abstract This paper presents a new fail mechanism for laser-marking induced die damage. Discovered during package qualification, silica spheres – commonly used as fillers in the molding material, was shown to act as a propagation medium that promote the direct interaction of the scribing laser beam and the die surface. Critical to the understanding of the fail mechanism is the deprocessing technique devised to allow layer by layer examination of the metallization and passivation layers in an encapsulated silicon die. The technique also made possible the inspection of the molding compound profile directly on top of the affected die area.

The article is devoted to some aspects of laser marking technology for machine parts. We consider the local impact zone effect of the pulse laser beam on the surface of metal materials. The results describing the influence of process parameters on the quality of the being marked images by pulsed laser are submitted. The examples of using barcode marking on several materials for machine parts in selected technological modes of installation are given.
