Solution For LED Thermal Management

CPS Corporation offers Aluminum Silicon Carbide (AlSiC), a metal matrix composite ideally suited for thermal management solutions for high brightness LEDs.

AlSiC enables a tailored coefficient of thermal expansion (CTE), offering compatibility with various electronic devices and assemblies. Unlike traditional housing materials, the isotropic CTE value of AlSiC can be adjusted for specific applications by modifying the Al-metal/SiC-particulate ratio.

Meeting the increased thermal behavior requirements for high brightness LEDs, AlSiC also exhibits a high thermal conductivity that results in thermal dissipation. Coupled with its superior CTE matching, AlSiC's high thermal conductivity effectively dissipates heat that can influence LED brightness, efficiency, color, and efficacy and product life time.

The CPS AlSiC near and net-shape fabrication process both produces the composite material and fabricates the product geometry allows rapid prototyping for high volume advanced thermal management solutions. The un-restricted geometry of AlSiC enables the inclusion of design features such as cavities, pedestals and alignment features. The unique casting process enables integration of very high thermal conductivity inserts (>1000 W/mK) or cooling tubes for more advanced thermal management solutions.
