Method for Pretreatment and Structuring of an Aluminum Oxide-Based Substrate

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a process for pretreating and structuring an aluminum oxide-based substrate, where the substrate is colored before it is structured using laser irradiation. Coloring the substrate prior to laser treatment helps the substrate absorb the laser energy more efficiently during the structuring process.

Use CasesContent extracted from patent full text and abstract with AI.

Patent Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Vorbehandeln und Strukturieren eines Substrats auf Aluminiumoxidbasis, wobei in dem Verfahren: das Substrat mittels Laserbestrahlung strukturiert wird, dadurch gekennzeichnet, dass vor der Laserbestrahlung zum Strukturieren, das Substrat eingefärbt wird, um die beim Strukturieren abgegebene Laserstrahlung zu absorbieren.
