EMBEDDED METAL STRUCTURES IN CERAMIC SUBSTRATES

摘要

The invention relates to a method for producing a substrate comprising embedded conductive metal structures or metallizations, in particular for use as printed circuit boards. The aim of the invention is to allow the buried metallization of three-dimensional, i.e. curved or angular, substrates in addition to the two-dimensional flat and level, i.e. plate-shaped, substrates. According to the invention, this is achieved in that trenches and/or recesses are dug into the substrate using laser technology, and the metal structures are then produced in the trenches and/or recesses.
