Thermal interface filler

• Chotherm (electrically insulating)
• Keratherm (electrically conductive, but with
  adhesive properties TBD).
• Sigraflex was discarded because too brittle.
• Dry contact (aluminum to aluminum) was discarded
  for thermal reasons because we need an high
  thermal conductance

Conclusions

• Keratherm adhesive looks to be electrically
  insulating.
• Final selection is therefore Chotherm.
• Crate-radiator contact is not the main electrical
  interface of the crates to the radiator
• each crate wall is grounded via a dedicated
  strap.
• Chotherm with PSA (self-adhesive) proposed

XPD assembly

• A. Assenza, E. Cortina, F. Hauler

21
Reissue of XPD ASSEMBLY NEW COPPER SPACER

• USE OF COPPER SPACER ONLY WHERE NEEDED (quantity
  in part list as required)
• The BUS BAR location is the same of EM model
• Integration procedure to be written

Florian, Eduardo, Mike, Mauro (?) agree with
Antonella

XPD FM CONCLUSIONS

• Assembly drawings will be updated and the
  sections views will we enclosed in the drawings.
• The number of bolts used to mount the busbar will
  be reduced
• (e.G. FROM 9 to 4 FOR THE TPD)
• Updated of partlist with correct lenght and qty
  of bolts

25
I-frames for DC/DC BOARDS

• I-frames will have a local chamfer to avoid
  contact with the board
• REISSUE OF DRAWINGS NEEDED

26
DC/DC BOARDS assy

• A cho-term foil will be added between the board
  and the I-frame ( it will be also included on
  assembly drawing and partlist)

TMM and GMM delivery

• TPD, T-crate , UPD and U-crate Thermal models
  have been delivered to NSPO.
• NSPO is now reviewing them.
