This invention describes a way to attach a heat sink to an electronic device. The heat sink has a raised border, or protrusion, on its surface. A pressure-sensitive adhesive is applied to the electronic device, which then sticks to the heat sink when pressed together, with the protrusion likely helping to manage a thermal interface material.
Why it matters: The increasing power density of electronic devices since 2019 has intensified the need for precise thermal management. Advances in thermally conductive pressure-sensitive adhesives and micro-fabrication techniques for heat sinks could make this specific design more viable and effective now.
