TC1050® Heat Spreader

High Conductivity

TC1050® heat spreader consists of a TPG® core encapsulated within a structural shell. The TPG® provides a highly conductive path while the encapsulation material provides the structure (strength, stiffness, and coefficient of thermal expansion). Common encapsulation materials include:
  • Aluminum (TC1050®.AL)
  • Copper (TC1050®.CU)
  • Other available encapsulations and systems include WCu, MoCu, AlSiC, stainless steel, Ni, etc.

Key Features

  • Significant improvement in thermal conductivity
  • Low thermal interface resistance
  • Reduction in component mass
  • Adjustable coefficient of thermal expansion
  • Wide operating temperature range
  • Mechanical load bearing
  • Hermeticity higher than 10-8 atm.cc/s
  • Vibration and shock resistance
  • Machinable
  • Plateable
  • Size up to 4 ft2 (0.37 m2) (TC1050®.AL)

Key Benefits

  • Improved Temperature Uniformity
  • Improved Component Reliability
  • Reduced Operation Temperature
  • Increased Power
  • Reduced Weight
  • Reduced Cooling Capacity Needs

Potential Applications

  • Heat spreader in electronic packaging
  • Thermal cores for PWB’s
  • Finned heat sinks
  • Avionic thermal cores
  • Satellite traveling wave tube (TWT) mounts
  • Electronic chassis
  • Cold plates in radar systems
