Detailed Product Description:
CVD Diamond Thermal Spreader Blanks: The Foundation for Advanced Thermal Management
We supply high-conductivity CVD Diamond thermal spreader blanks – precision-engineered materials designed for customers who perform their own die attach and advanced packaging integration. As an upstream material supplier, we provide the building blocks; our customers handle the final assembly.
Why CVD Diamond for Thermal Management?
CVD diamond possesses the highest thermal conductivity of any bulk material, reaching up to 2000 W/m·K – over five times that of copper . This exceptional property makes it uniquely suited for removing heat from localized hotspots in high-power electronic devices . When integrated as heat spreaders, diamond effectively lowers dissipation density and provides a lower thermal resistance path, directly improving device performance and
reliability .
For power amplifiers, CVD diamond heat spreaders enable:
Higher power operation at a given maximum operating temperature
Lower peak temperatures at a given power level
Up to 30% reduction in thermal resistance when integrated into RF packages
Our CVD Diamond Thermal Spreader Products
We offer CVD diamond blanks with precision metal coatings, ready for your existing assembly processes:
Chrome-coated CVD diamond: Provides excellent adhesion for subsequent metallization layers
Copper-coated CVD diamond: Combines diamond's thermal superpowers with copper's electrical conductivity and solderability – achieving thermal conductivity values around 800 W/m·K, approximately 2.5 times higher than pure copper alone . This innovative composite material is specifically designed for AI chips in data center HPC applications, RF power amplifiers for wireless communications, power modules for reliable power conversion, and semiconductor lasers .
Silver-coated CVD diamond: Offers superior thermal and electrical performance for the most demanding applications
Metallization for Die Bonding
Bare diamond cannot be directly soldered into packages. Our metallization solutions enable die bonding with low thermal barrier resistance, consistent with industry standard soldering and brazing processes -2. Standard metallization configurations include Ti/Pt/Au and solder metallization options such as Ti/TiN/Ti/AuSn and Ti/Pt/AuSn .
Key Specifications
Our CVD diamond thermal spreader blanks are available with:
Thermal conductivity grades: 1000, 1500, 1800, and 2000 W/m·K options to match your specific requirements
Thickness range: 0.2mm to 3mm, with standard thicknesses of 0.30mm, 0.40mm, and 0.50mm available
Dimensions: Custom sizes laser-cut to your exact specifications, with standard 10×10mm plates readily available
Surface finish: Device side polished to Ra < 50nm, substrate side Ra < 250nm
Edge quality: Precision laser-cut edges with tight tolerances
Applications
Our metalized CVD diamond thermal spreader blanks are ideal for:
GaN and SiC power devices: Diamond heat spreaders enable higher power densities and improved reliability in RF amplifiers and power electronics
High-power laser diodes: Diamond's unmatched thermal conductivity manages extreme heat fluxes in optoelectronic devices
RF amplifiers and 5G infrastructure: CVD diamond reduces thermal resistance by approximately 30% in RF packages
AI processors and high-performance computing: Copper-diamond composites address the growing thermal challenges in data center applications, where more than 50% of electronic device failures are heat-related
Power modules and IGBTs: Diamond heat spreaders enable higher power operation within existing module footprints
Our Position in the Supply Chain
