Abstract
A component carrier includes a stack having a first electrically insulating layer structure and a first electrically conductive layer structure arranged on the first electrically insulating layer structure. The first electrically insulating layer structure has at least one first covered portion, which is covered by the first electrically conductive layer structure, and at least one first non-covered portion, which is not covered by the first electrically conductive layer structure. The first electrically insulating layer structure defines a recess at the at least one first non-covered portion.
