Mounting structure

A mounting structure comprising:

• a package on whose upper surface an electronic component is mounted;
• a voltage regulator module mounted on a facing position on a lower surface of the package, the facing position being where the voltage regulator module faces the electronic component;
• a mother board for mounting the package on an upper surface of the mother board;
• a driver mounted on a facing position on a lower surface of the mother board, the facing position being where the driver faces the package;
• and
• a plurality of connectors for electrically connecting a conductor layer of the mother board and a conductor layer of the package to each other,
• wherein the mother board comprises a first through hole for accommodating the voltage regulator module therein and a second through hole for passing one or some of the connectors from the upper surface to the lower surface of the mother board,
• an end portion of the one of the connectors passing through the second through hole or an end portion of the some of the connectors passing the second through hole is connected to the conductor layer on the lower surface of the mother board near the driver and another end portion of the one of the connectors passing through the second through hole or another end portion of each of the some of the connectors passing through the second through hole is connected to the conductor layer on the lower surface of the package near the voltage regulator module,
• a heat sink is connected to the voltage regulator module via the first through hole for accommodating the voltage regulator module therein, and
• wherein the diameter of the second through hole is larger than the diameter of the connector, and in the inside of the second through hole, at least a part of the connectors penetrates the second through hole without touching an inner surface of the second through hole.
