Abstract
This disclosure provides a circuit board assembly and a manufacturing method thereof. The circuit board assembly includes circuit board, embedded chip, heat dissipation assembly and temperature switch structure. The temperature switch structure includes a first metal layer and a second metal layer stacked on each other. The first metal layer of the temperature switch structure is electrically connected to the circuit board and is thermally coupled to the embedded chip. A thermal expansion coefficient of the first metal layer is different from a thermal expansion coefficient of the second metal layer so that the temperature switch structure is deformed in response to a temperature change of the embedded chip to be in contact with or spaced apart from the second electrically conductive contact of the heat dissipation assembly.
