Abstract: A molded interconnect device (MID) with a thermal conductive property and a method for production thereof are disclosed. A thermal conductive element is set in a support element to improve the thermal conductivity of the support element, and the support element is a non-conductive support or a metallizable support. A metallization layer is formed on a surface of the support element. If a heat source is set on the metallization layer, heat produced by the heat source will pass out from the metallization layer or the support element with the thermal conductivity material element.

Abstract: A manufacturing method of forming an electrical circuit on a non-conductive carrier comprises following steps. After providing an electrically non-conductive carrier, catalysts are dispersed on or in the electrically non-conductive carrier. A predetermined track structure is formed on the electrically non-conductive carrier to expose the catalysts on the surface of the predetermined track structure. The surface of the predetermined track structure containing the catalysts is metalized to form a conductor track.
