Abstract:
A chip scale package structure of heat-dissipating type is provided and includes a board, a die fixed on and electrically coupled to the board, a thermally conductive adhesive sheet adhered to the die, and a package body formed on the board. The die has a heat-output surface arranged away from the board. The thermally conductive adhesive sheet is connected to at least 50% of an area of the heat-output surface. The package body covers and is connected to the die and entire of the surrounding lateral surface of the thermally conductive adhesive sheet. The die is embedded in the board, the thermally conductive adhesive sheet, and the package body. The heat-dissipating surface of the thermally conductive adhesive sheet is exposed from the package body, and a thermal conductivity of the thermally conductive adhesive sheet is at least 150% of a thermal conductivity of the package body.
