Abstract
A method for serializing ceramic substrates in which a laser is used to remove unfired paste material from an unfired ceramic substrate. The paste material is removed by exposing the unwanted paste material to laser radiation in a programmed sequence of x and y coordinate moves. The laser radiation removes the unwanted paste material, leaving the identifying characters intact. The identifying characters can be used for part identification and traceability.
