Torque Sequence

Torque Sequence

BASE
  1. screw studs into heat sink
  2. place thermocouple in groove
  3. place thermoelectrics on heat sink
  4. place heat spreader on thermoelectrics
  5. insert thermocouple into heat spreader
  6. set up insulation
  7. insert cartridge heater
  8. use fine wire to hold insulation in place
  9. place thermocouple on top of insulation
  10. while holding the thermocouple from step 9, slide the clamping plate onto the studs
  11. add washers in correct stack up (shown in "Washer Stackup")
  12. finger tighten clamping nuts
  13. torque nuts in sequence (shown in "Torque Sequence") to 5 in-lbf
  14. place gasket on heatsink. use screws to hold in place

COVER

  1. attach a thermocouple to ch4 and place against the side of the enclosure
  2. line the enclosure with fiberglass insulation

COVER ON LID

  1. align thermocouple and electrical connections before attempting to put lid on
  2. holding cover above the base at an angle, attach the three thermocouple connections and the electrical connection on the cover to the respective connections on the base.
  3. place fiberglass insulation over the top corner of the clamping plate to ensure it doesn’t melt the power cables on the cover.
  4. lower the cover onto the gasket, ensuring that no insulation or wiring is trapped between the cover and the base.
  5. screw the cover to the base using the countersunk screws until snug.
  6. Torque the screws down as tight as possible using the same torqueing sequence as used for the clamping plate.

LEGS

  1. screw legs to base with a gasket in between. The gasket helps prevent corrosion between the base and the legs.
  2. Note that the legs should be flush with the base of the fins.
