Abstract
A method of manufacturing a component carrier is disclosed. The method includes providing an electrically insulating layer structure having a front side and a back side, wherein the front side is covered by a first electrically conductive layer structure and the back side is covered by a second electrically conductive layer structure, carrying out a first opening process, such as a first laser drilling, through the first electrically conductive layer structure and into the electrically insulating layer structure from the front side to thereby form a blind hole in the electrically insulating layer structure, and thereafter carrying out a second opening process, such as a second laser drilling, through the second electrically conductive layer structure and through the electrically insulating layer structure from the back side to thereby extend the blind hole into a through hole, in particular a laser through hole, with substantially trapezoidal shape.
