  • Patent number: 11798863
    Abstract: The problem to be solved by the invention is to provide a laminate capable of effectively enhancing thermal conductivity and adhesiveness, in spite of the relatively large thickness of a patterned metal layer. The laminate (1) according to the present invention includes a metal substrate (4), an insulating layer (2) laminated on one surface of the metal substrate (4), and a patterned metal layer (3) laminated on the surface of the insulating layer (2) on the side opposite to the metal substrate (4), the metal layer (3) is 300 ?m or more in thickness, and the insulating layer (2) includes boron nitride (12) and an inorganic filler (13) other than boron nitride.

  • Patent number: 10356946
    Abstract: The present invention provides a heat dissipation structure that does not cause problems such as contact failures in electronic components and that is applicable to electronic components with high heat densities. The present invention also provides a method for easily repairing an electronic device. The heat dissipation structure is obtained by filling and curing a thermally conductive curable resin composition in an electromagnetic shielding case on a substrate on which an electronic component with a heat density of 0.2 W/cm2 to 500 W/cm2 is mounted, the thermally conductive curable resin composition containing a curable liquid resin (I) and a thermally conductive filler (II), having a viscosity at 23° C. of 30 Pa·s to 3000 Pa·s and a thermal conductivity of 0.5 W/(m·K) or more, and being curable by moisture or heat.
