Abstract: A power module of a square flat pin-free packaging structure for suppressing the power module from being excessively high in local temperature. The power module includes an insulating resin, a driving chip, a plurality of power chips, and a plurality of metal electrode contacts. The driving chip, the power chips, and the metal electrode contacts are electrically connected through a metal lead according to a predetermined circuit. A plurality of metal heat dissipating disks used for heat dissipation of the power chips and a driving chip lead frame are disposed at the bottom of the insulating resin. A plurality of metal power chip lead frames are disposed on the metal heat dissipating disks, the power chips are disposed on the power chip lead frames, and the drain electrodes of the power chips are electrically connected to the metal heat dissipating disks.
