Abstract

The invention discloses a packaging method of an intelligent power module and the intelligent power module. The method comprises the steps: carrying out the conductive paste printing on the outer surface of a first resin layer after the intelligent power module completes first resin layer packaging, wherein a power chip in the intelligent power module is arranged in the first resin layer; and carrying out second resin layer packaging on the intelligent power module printed by the conductive paste to obtain a packaged and formed intelligent power module, wherein a driving chip of the intelligent power module is placed in the second resin layer. The technical problems that a traditional intelligent power module is electrically connected in a lead bonding mode, so that stray inductance is high, and the current bearing capacity is insufficient are solved.

Description

technical field [0001] The invention relates to the field of packaging without welding wires, in particular to a packaging method for an intelligent power module and the intelligent power module. Background technique [0002] In the related technology, due to the large overcurrent of the intelligent power module and the large heat generation of the power chip, the traditional intelligent power module is electrically connected by wire bonding, which will lead to high stray inductance and fatigue damage at the solder joints of the bonding wires. , Insufficient current carrying capacity, low bonding efficiency and other issues. At the same time, in the traditional intelligent power module, the driver chip IC is placed near the switch chip IGBT. Due to the poor high temperature resistance of the driver chip IC, it will cause interference and distortion of the driving signal. [0003] For the above problems, no effective solution has been proposed yet. Contents of the inventio...
