Thermal Links/Straps

Thermal links efficiently transfer heat from a heat source to a temperature sink while minimizing transfer of mechanical loads. The proprietary SDL process uses no filler materials (solder, epoxy, etc.) to connect a stack of foils (or braids) to end blocks that can be adapted to complex geometry to maximize thermal performance.


  • Over 700 thermal links fabricated for over 50 contracts
  • Solderless design for maximized performance
  • Enables a high degree of flexibility
  • Minimizes weight
  • Conducts heat with minimal temperature loss
  • Protects fragile cryocooler cold fingers
  • Decreases contamination risks associated with previous thermal techniques
  • Adapts easily to new design parameters
  • Removes contact resistance between metals
  • Extensive space-flight heritage



Wide-field Infrared Survey Explorer

The WISE cryogenically-cooled infrared telescope provided a complete stellar infrared map more than 1,000 times more detailed than previous surveys.

JWST Thermal Links

James Webb Space Telescope

SDL developed thermal links to transport heat from JWST’s science instruments to their radiators, enabling each instrument to operate at desired temperatures.


Sounding of the Atmosphere using Broadband Emission Radiometry

SABER, a 10-channel infrared (1.27 to 16.9 µm) radiometer, is one of four instruments on NASA's TIMED mission, which is dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere.
