Circuit board module

A circuit board module comprising:

• a first circuit board that has a first main surface on which a power semiconductor device is mounted and a second main surface and that configures a power conversion circuit;
• and
• a second circuit board having a third main surface and a fourth main surface on which is mounted a load that is configured to receive a current supplied by the power conversion circuit and is electrically connected to the fourth main surface,
• wherein
• the first circuit board includes a positive output pin of the power conversion circuit and a negative output pin of the power conversion circuit, each of which has a shape projecting from the second main surface,
• the second circuit board has a positive through via and a negative through via, each of which has a shape extending between the third main surface and the fourth main surface,
• the second main surface of the first circuit board and the third main surface of the second circuit board are physically in proximate contact with each other,
• the positive output pin is inserted through the positive through via in such a manner as to reach the fourth main surface,
• the negative output pin is inserted through the negative through via in such a manner as to reach the fourth main surface, and
• the load is configured to receive the current supplied from the power conversion circuit through the positive output pin and the negative output pin.
