A component carrier assembly includes a first component carrier having a first electrically insulating layer structure and a via in the first electrically insulating layer structure, where the via is at least partially filled with electrically conductive material and where an upper part of the via extends beyond an outer main surface of the first component carrier; and a second component carrier having a second electrically insulating layer structure, and an electrically conductive adhesive material that is at least partially embedded in the second electrically insulating layer structure. The first component carrier and the second component carrier are interconnected and the upper part of the via at least partially penetrates into the electrically conductive adhesive material.

Component carrier interconnection and manufacturing method

A component carrier having a stack with at least one electrically conductive layer structure and at least one electrically insulating layer structure; an opening located at least partially in the stack; and a fill material which is located within the opening. The fill material is a photosensitive material, wherein at least a part of the photosensitive material has undergone a hardening treatment with electromagnetic radiation. A method for manufacturing such a component carrier is further described.

An electronic device includes a first component carrier having a first stack with at least one first electrically conductive layer structure and/or at least one first electrically insulating layer structure, a second component carrier having a second stack with at least one second electrically conductive layer structure and/or at least one second electrically insulating layer structure, and an intermediate structure including at least three staggered electrically conductive and coupled vertical interconnect elements in an at least partially dielectric sheet and being directly connected between the first component carrier and the second component carrier for electrically coupling the first component carrier with the second component carrier.

Component carriers connected by staggered interconnect elements

A component carrier includes (a) a base structure having a surface with a surface profile; (b) a first dielectric layer formed on the surface of the base structure and (c) a second dielectric layer formed on the first dielectric layer. The first dielectric layer has a first main surface with a first surface profile. The first main surface faces away from the surface of the base structure. The first surface profile corresponds to the surface profile of the base structure. The second dielectric layer includes a second main surface with a second surface profile. The second main surface faces away from the surface of the base structure. The second surface profile differs from the surface profile of the base structure. A manufacturing method uses an auxiliary sheet for pressing the first dielectric layer on the main surface. The auxiliary sheet is removed before pressing the second dielectric layer.
