Patent ID: 8076586

Claim:
A circuit-board construction, comprising: an insulating-material layer; at least two conductor pattern layers; at least one component inside the insulating-material layer; electrical vias to connect the component electrically to at least one of the conductor pattern layers; and at least one thermal via in the insulating-material layer in the vicinity of the component, wherein at least one electrical via connected to said component and at least one thermal via in the vicinity of said component are situated on a first surface of the insulating-material and are formed from the same solderless material, at least one of the conductor pattern layers is situated on the side of the first surface of the insulating-material layer and at least one other of the conductor pattern layers is situated on the side of a second surface, opposite to the first surface, of the insulating-material layer, and at least one thermal via is connected to the conductor pattern layer on the side of the first surface and at least one other thermal via is connected to the conductor pattern layer on the side of the second surface.
