Application: Conductive heat radiation film, method of manufacturing the same, and method of manufacturing electronic device (Patent ID: US20240047299A1)

The patent filed by Fujitsu Ltd. describes a method for manufacturing a conductive heat radiation film that includes growing carbon nanotubes over a substrate, applying a paste with metal particles to the tips of the nanotubes, forming a heated film by heating the paste, and then peeling the nanotubes from the substrate. The metal particles can be silver or copper, with specific temperature requirements during the manufacturing process.

Furthermore, the method extends to manufacturing an electronic device by sintering the heated film to a component, connecting the nanotubes to another component, and forming a sintered film. The process involves specific temperature conditions for sintering, different metal particles, and the creation of coating films to enhance the connection between components. The resulting electronic device benefits from the conductive heat radiation film's flexibility and density, providing improved thermal management capabilities.
