摘要
The thermal resistance of an entire semiconductor package with a semiconductor chip and radiation fins is calculated based on thermal resistance of resin between the semiconductor chip and case, thermal resistance of the radiation fins, and thermal resistance of three heat radiation paths in the semiconductor package. One of said three heat radiation paths is passing through the bottom surface of the case. The other of said three radiation paths is passing through the leadframe. The other of three radiation paths is passing through sides of the case other than the leadframe.
