Thermal Straps

Onsite Testing and Services

SDL provides end-to-end solutions including design, fabrication, and testing—all performed onsite.

Thermal Testing

  • Conductance tests simulating end-use conditions
    • Sink temperature range: 4 K to 318 K (-269℃ to 45℃)
    • Typical vacuum pressures 10-6 to 10-7 torr
    • Interface filler: Indium, gold, dry, or custom
    • Lakeshore DT-670-CU silicon diode & CX-1070-CU Cernox temperature sensors
    • Lakeshore 218 and 224 temperature monitors
  • Thermal cycling (vacuum, air, or inert gas) from 4 K to ≥398 K (-269℃ to ≥125℃) depending on environment
