CuMoCu: Copper-Molybdenum-Copper Laminates
 
Cu/Mo/Cu laminates developed have an adjustable coefficient of thermal expansion that can be correlated with a range of semiconductor substrates while simultaneously maintaining high thermal conductivity. These aspects make them a perfect choice for high power devices where significant heat is produced.
 
Application : Microwave carriers, and heat sinks, BGA packages,LED packages, GaAs device mounts.
 
\
Cu/Mo/Cu laminates also have moderate thermal conductivity and low thermal and electrical resistance. They are suitable for Si-based devices as well as for large area power devices with significant heat generation.
 
Thermal Conductivity and Thermal Expansion-Mismatch
Thermal conductivity and the coefficient of thermal expansion-mismatch of a given die are some of the key parameters involved in selecting a heat spreader material. These two parameters can be calculated by introducing a Thermal Compatibility Factor for a given heat spreader material in a simple equation: (Heat Spreader) / A CTE (Die - Heat Spreader). The ensuing ratio may be utilized to assess the compatibility of a heat spreader material with a given die. A high compatibility factor results from a low coefficient of thermal expansion-mismatch and a high thermal conductivity value.
