Within **IGBT modules**, heat starts at the chip and travels outward. The path looks like this:

- Chip junction
  - Solder layer
  - Baseplate
  - **IGBT module thermally conductive insulating sheet**
  - Heat sink

At each interface, **열 저항** adds up. Lower it, and **접합부 온도** drops. That’s the game.

1. Heat generated by switching increases **전력 밀도**.
2. Heat must pass through a **열 인터페이스 재료**.
3. 그리고 **IGBT module thermally conductive insulating sheet** 개선 **열 전달** by filling micro air gaps.

Short version? Better **열 전도성** means longer **디바이스 안정성**. A well-designed **IGBT module thermally conductive insulating sheet** reduces hotspots and keeps performance stable even during heavy cycling.

### How IGBT Modules Benefit from Dielectric Strength and Electrical Insulation

Heat is only half the story. Voltage isolation matters just as much.
