Abstract
The present disclosure provides a power module assembly and an assembling method thereof. The power module assembly includes a housing, a circuit board, at least one resilient set, at least two power devices, and at least one fastening unit. The housing includes at least one heat-dissipation surface. The at least one resilient set is disposed between the housing and the circuit board and includes at least one resilient piece. Each resilient piece includes a base section and two pushing fingers, so as to form an M-word shape or a bird-wings shape. The fastening unit is disposed between the two power devices, connected to the base section of the resilient piece and configured to drive the base section of the resilient piece, so that the two pushing fingers of the resilient piece push against the two power devices respectively and the two power devices are attached to the heat-dissipation surface.
