  1. AIDA Mezzanine board Contacts for underside connectors Thermal contact pads 1

  2. AIDA Location pins Heatsink Chip separation block Holes for underside connector This is to be assembled as a single unit 2 Light-tight area

  3. AIDA Max temp 44ºC Still have remainder of thermal path to consider 3

  4. AIDA Mezzanine card assembled to Motherboard so that we have an independent FEE64 card 4

  5. AIDA FEE64 cards fastened to intermediate plate FEE64 cards 8mm thick intermediate plate Location pins Socket guide 5 Overlapping sockets

  6. AIDA Motherboard cooling plates Dow Corning type foam 6

  7. FEE Mechanics AIDA Cooling channels Moving Plate Fixed Plate Side Plates Mechanics consists of 4 main parts Moving plate, Fixed plate and 2 side plates. Dow Corning type foam Guide channels 8

  8. AIDA FEE64 Module Dow Corning type foam not used at this location for Agata Necessary for Aida, as it for example central module is slightly higher than other two, (due to mechanical tolerance build up) it could reduce the level of cooling available for the other modules 9

  9. AIDA Female part of connector Manual level at this end to push connectors together (not shown yet) Wheels drop into pockets at this point Some float will be required in this board. (not shown yet) 10

  10. AIDA Boards in ‘correct’ orientation Boards rotated anti-clockwise Boards rotated clockwise Boards inverted I don’t mind the inverted boards, as it doesn’t affect the mechanics, but I would prefer to avoid the clockwise and anti-clockwise boards 11

  11. AIDA Kapton Ribbon cable All Mechanics in same orientation Detector Detector Connection boards 12

  12. AIDA There are 3 ways to do this 1. Make two different detector connection boards, 1 for the vertical option, and 1 for the lateral options. 2. Make 1 detector connection boards, with 2 sockets for the kapton cable. Only 1 of which is used. 3. Twist the cables… Split connectors for ribbon cable lateral position 13
