Classification: CPC E  C | IPC C  E

Claim 5:
6. A method of making a composite product; the method including:
providing a body of polycrystalline diamond (PCD) material having a PCD proximal end and a PCD distal end, the body including an electrically insulating portion;
providing an electronic device including an electronic component and having a device surface;
providing metallic join material having a liquidus temperature of 600° C. to 950° C. at atmospheric pressure, and capable of chemically bonding to the body of PCD material and the device surface;
arranging the metallic join material between the device surface and the distal PCD end, the metallic join material being electrically insulated from the PCD proximal end by the electrically insulating portion;
heating the metallic join material to a temperature of at least the liquidus temperature and no greater than 950° C., to allow the metallic join material to melt and connect the PCD body and the device surface; and
allowing the metallic join material to cool and solidify to form the connection portion, the electrically insulating portion electrically insulating the connection portion from the PCD proximal end.
