  • Patent number: 8709197
    Abstract: A bonding material is placed on an electronic component. a heat conductive member is superposed on the surface of the bonding material so that a thermosetting adhesive is interposed between the heat conductive member and a substrate. The thermosetting adhesive is then cured at a temperature lower than the melting point of the bonding material. The bonding material melts after the thermosetting adhesive has cured. While a distance is maintained between the heat conductive member and the substrate, the thermosetting adhesive is cured. The heat conductive member is thus reliably prevented from a downward movement regardless of the melting of the bonding material. A space is maintained between the heat conductive member and the electronic component. The cured bonding material is reliably prevented from suffering from a reduction in the thickness.
