Fairchild Eng. & Science CCDs Frame operations.

Status, August 9th, 2007

The following is a complete set of pictures taken in the AITC Clean Room
(Room LG1.13), last Thursday (August 2nd).
These pictures show the Engineering CCD having its handling frame replaced
after a cold run (at T=-120C) with no frame and then the Science detector having
the original frame removed and our new one installed, prior rto installing in the
Test Dewar (#2).
The handling frame is left in-situ as the detector is very difficult to manipulte
without this in place. The new design is meant to provide more space for the detector
bond wires, and, a new safety feature so the frame can't be tilted and impact the
delicate wires.

Clean Room Picture details.

• 1. Enginerring CCD removed from Dewar and mounted in handling tool.
• 2. Close up of above.
• 3. Close up of Eng. CCD & Flex interconnect.
• 4. Underside of Eng. CCD before shorting strips are installed.
• 5. Close up of side of Eng CCD.
• 6. Eng. CCD just after its Flex interconnect was removed.
• 7. Eng. CCD mounted on jig ready to have the new frame replaced after it had
  been removed to undertake a cold test without it.
• 8. Close up of above before frame lifted into place.
• 9. Novel means of securing frame while screws installed!
• 10. Another view of hex drive holding frame in place.
• 11. New Frame in place and secured with glass cover slip in place.
• 12. Eng. CCD removed from mounting jig.
• 13. Underside of FI Science CCD #2 - showing shorting strips in place.
• 14. Fit check for the flex interconnects to ensure device round the right way!!
• 15. Another view - this time with shorting strips removed.
• 16. Science device installed on mounting jig.
• 17. Science device now with old (shipped) frame removed (lowered.
• 18. Another view of Science device on handling jig.
• 19. Science device picked up in 'grappler' so that old frame can be
  removed from the handling jig and the new one installed in its place.
• 20. 'Grappler' sresting on block with CCD firmly secured in place -
  this is achieved by tightening the black, knurled knob on the right.
• 21. New RSAA designed handling frame in place.
• 22. Science CCD lowered onto handler ready to have new frame drawn up to CCD.
• 23. Close up of above.
• 24. Another close up this time showing frame raised and in place and
  secured by hex drive.
• 25. Another view showing both hex drives securing frame in place and one
  of the frame screws installed.
• 26. All 4 screws now in place and hex drives removed.
• 27. Glass cover slip has been re-installed and the device removed from
  the handler to have the flex interconnects installed.
• 28. Close up of back of CCD before flex attached.
• 29. Detector mount block with screws in place ready to receive CCD.
• 30. CCD mounted onto mount block - flex installed and whole unit ready to
  be mounted in the Test System.
• 31. CCD mounted in test system with glass cover slip in place. Reflection of
  E2V CCD handler can be seen in the glass cover slip!
• 32. Final view with the glass cover slip removed and the Dewar top ready to
  be installed before pumping and cooling.
