Product Description
Lasing diode/MCM/CPU components tungsten copper heat sinks
They are composites of tungsten and copper. So both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.
By adjusting the content of tungsten, we can have its coefficient of thermal expansion (CTE) designed to match those of materials such as ceramics (Al2O3, BeO), semiconductors (Si), and metals (Kovar), etc.
Used as Thermal mounting plates,chip carriers,flanges, frames for RF and substrates etc.
Advantages
1.High thermal conductivity
2.Excellent hermeticity
3.Excellent flatness, surface finish, and size control
4.Semi-finished or finished (Ni/Au plated) products available
5.CTE closely controlled to match ceramics (Al2O3, BeO), semiconductor (Si), metals like Kovar, etc.
Properties
Content (wt%) | Cu (wt%) | W (wt%) | Density (g/cm³) | Coefficient of thermal conductivity (W/m2.K) | Coefficient of thermal expansion (×10-6/K) |
WCu10 | 10±2 | the rest | 16.8 | 160-180 | 6.3-6.8 |
WCu15 | 15±2 | the rest | 16.1 | 180-200 | 7.0-7.5 |
WCu20 | 20±2 | the rest | 15.2 | 190-210 | 8.0-8.5 |
WCu25 | 25±2 | the rest | 14.5 | 200-230 | 9.0-9.5 |
WCu30 | 30±2 | the rest | 13.80 | -240 | -9.7 |
Applications
As a copper tungsten material, it’s a composite. So both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.
The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates.
Tungsten copper heat sinks are extensively used in thermal mounting plates, chip carriers, flanges, and frames for RF, microwave millimeter wave packages like LDMOS FET; MSFET; HBT; Bipolar; HEMT; MMIC, light emitting diodes and detectors, laser diode packages like pulse, CW, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable
