Abstract
A signal-heat separated TMV packaging structure includes an insulating dielectric material, an inner signal line layer arranged in the insulating dielectric material, an outer signal line layer, a heat dissipation metal face and a chip. A first side of the insulating dielectric material is provided with an isolating layer. The outer signal line layer is arranged on a surface of a second side of the insulating dielectric material and is connected with the inner signal line layer through a TMV structure. The heat dissipation metal face is arranged on a surface of the first side of the insulating dielectric material, and is separated from the inner signal line layer. The chip is embedded in the insulating dielectric material, with an active face in electrically-conductive connection with the inner signal line layer and a passive face in heat transfer connection with the heat dissipation metal face.
