Abstract
A component carrier including a stack having at least one electrically conductive layer structure and at least one electrically insulating layer structure. The at least one electrically insulating layer structure includes i) an insulating material, and ii) fillers embedded in the insulating material. At least one of said fillers is exposed at one of the main surfaces of the electrically insulating layer structure. The at least one exposed filler includes a high-roughened surface portion and a low-roughened surface portion.
Claims20
A component carrier, comprising:
- a stack having at least one electrically conductive layer structure and at least one electrically insulating layer structure, wherein the at least one electrically insulating layer structure comprises:
- an insulating material, and
- fillers embedded in the insulating material,
- wherein at least one of said fillers is exposed at one of the main surfaces of the at least one electrically insulating layer structure;
- wherein said at least one exposed filler comprises a high-roughened surface portion and a low-roughened surface portion.
A method of manufacturing a component carrier, the method comprising:
- providing a stack comprising at least one electrically conductive layer structure and at least one electrically insulating layer structure, wherein the at least one electrically insulating layer structure has an exterior main surface portion defined at least partially by an insulating material and fillers which are embedded in the insulating material;
- and
- treating the exterior main surface by laser ablation from a laser source, to thereby roughen an exposed surface portion of at least one filler.
Using an excimer laser to perform a desmear process with respect to an exterior main surface of an electrically insulating layer structure, having fillers embedded in an insulating material, of a component carrier stack.
