AI Technical Summary

Technical Problem

In the prior art, the ceramic substrate of the power module is prone to cracking due to excessive clamping force or excessive thermal paste, resulting in reduced voltage resistance and leakage faults.

Method used

By incorporating a support component within the power module, the locking force is prevented from acting directly on the ceramic substrate. Instead, the support component connects to the heat sink, supporting the outer casing and thus distributing the force evenly, preventing direct pressure damage to the ceramic substrate.

Benefits of technology

It effectively prevents the ceramic substrate from cracking, improves the stability and pressure resistance of the module, avoids failures caused by loose or overtightened bolts, and enhances the reliability of the power module.

Abstract

本申请提供了一种功率模块与电子设备,涉及半导体封装技术领域。该功率模块包括外壳、陶瓷基板、芯片、导热膏、散热片、支撑件以及固定件,芯片、陶瓷基板、导热膏以及散热片逐层设置,外壳盖设于陶瓷基板上,且外壳内设置有容置空间,芯片位于容置空间内;支撑件的两端分别与外壳的底部、散热片连接,以支撑外壳;固定件用于连接外壳与散热片,以固定外壳与散热片。由于本申请中通过设置支撑件的方式,将陶瓷基板与散热片之间连接实现支撑,使得锁附力不会直接作用于陶瓷基板上,而是作用于散热片,因此陶瓷基板不容易出现破裂的问题。
