Metal-Based Composite Materials
- MMC (Ai/SiC Composite Material)
- We provide metal-based composite materials such as Metal Matrix Composites (Ai/SiC) and Cu-Mo, which are primarily used in spacers, substrates, and housings.
Spacer
- Introduction
- Double-sided cooling technology is a new structural technology for recent power module products, effectively reducing the parasitic inductance and resistance of the device, and effectively improving the power density and reliability of the device. This product serves primarily as a key material for devices such as double-sided cooling devices, playing a crucial role in "thermal conduction", "electrical conduction", and "support".
- Application Fields
- Spacer-related products are used in fields such as new energy vehicles, power elctronics, and smart grids.
- Product Features
-
- High thermal conductivity
- Low expansion
- High electrical conductivity
- Strong bonding
- Good weldability
