  • Patent number: 8304889
    Abstract: An elastic printed board is provided so that stress applied by the silicon gel is absorbed by the printed board. Further, the printed board is formed to be so narrow that the stress can escape. On the other hand, the wires on which a high voltage is applied are patterned on respective printed boards. This serves to prevent discharge through the surface of the same printed board serving as a current passage. This design makes it possible to hermetically close the power module, prevent intrusion of moisture or contamination as well as displacement, transformation and cracks of the cover plate.
