High-Density W–Cu Heat Spreading Substrates for Power & RF Devices
Key Features
- High Thermal Conductivity: Rapidly spreads heat away from power devices to prevent hotspots.
- Tailored CTE: Matches Si, GaN, GaAs, or SiC to minimize thermal stress.
- High-Temperature Stability: Maintains performance under continuous high-power operation.
- Dimensional Accuracy: PM processing ensures tight tolerances and minimal warpage.
- Surface Compatibility: Suitable for Ni/Au plating, soldering, and direct bonding.
- Hermetic Package Reliability: Supports durable bases for hermetic enclosures.
- PM vs. Traditional Processing: Outperforms milling or casting for dense W–Cu by reducing machining, scrap, and thermal distortion while enabling complex geometries.
Overview
NEWLIFE Tungsten–Copper (W–Cu) Thermal Substrates are precision-engineered solutions for high-power semiconductor packaging, RF modules, and high-performance LED and laser bases. These substrates deliver efficient heat spreading, low thermal resistance, and controlled coefficient of thermal expansion (CTE) tailored to semiconductor materials such as Si, GaN, GaAs, and SiC.
Manufactured via Powder Metallurgy (PM) and sintering–infiltration, NEWLIFE W–Cu substrates offer high density, uniform microstructure, and excellent dimensional stability under repeated thermal cycling. Unlike conventional machining or die-casting, PM enables near-net-shape production of complex plates, blocks, and heat spreader blanks, reducing material waste, machining time, and residual stresses in high-density W–Cu composites. NEWLIFE's proprietary powders ensure predictable sintering behavior, superior purity, and optimal thermal performance across the substrate.
The combination of high mechanical strength, thermal conductivity, and tailored CTE makes these substrates ideal for precision electronic assemblies where thermal management and structural reliability are critical.
