Balancing thermal conductivity, expansion, and structural stability
In electronic packaging, the material must move heat away from the device while staying compatible with the expansion behavior of adjoining materials. Tungsten copper is widely used for this reason.
WCu Electronic Packaging Materials are composite material systems composed of tungsten and copper, combining the low thermal expansion and high strength of tungsten with the high thermal conductivity and electrical conductivity of copper.
Manufacturing & Quality Control
WCu electronic packaging materials are typically manufactured using tungsten skeleton sintering followed by copper infiltration for uniform structure and stable performance.
- Tungsten skeleton pore structure control
- Copper infiltration completeness and uniformity
- Structure density and composition stability
- Thermal conductivity and thermal expansion matching control
- Surface flatness and machining accuracy
Selection Recommendations
Choose the right WCu grade for your application:
- **Packaging thermal management**: confirm device heat flux and thermal expansion matching requirements
- **Subsequent plating, brazing, or welding**: confirm surface treatment and substrate compatibility
- **High-power applications**: focus on thermal conductivity and CTE matching with semiconductor materials
RFQ Guide
For thermal management components, please include:
1. Required WCu grade or target thermal conductivity level
2. Part drawings or target dimensions
3. Whether flatness or precision machining is required
4. End application type (power module, RF device, laser, etc.)
5. Whether plating, brazing, or packaging process is involved
6. Batch requirements
