  1. IB module assembly A. Di Mauro (CERN) WP6 meeting 30.01.2014

  2. Requirements • Chip position accuracy ~ 5 mm • Time ~ 2-3 h/HIC • Minimum material budget • Full repeatability/reliability • “Reworkability” (as much as possible)

  3. IB module assembly steps • Placement of chips on vacuum table and position check • Placement of flex on vacuum table and alignment • Placement of soldering grid on flex and alignment • SnAg soldering balls deposition and check • Soldering of one chip and check • Repeat steps 4 and 5 for all chips • Final check of chips position Comments related to use of artificial vision based automated system: • Steps 1-3: positioning/alignment done at the same time by a.v. • Step 4: soldering balls presence checked by a.v., possibility to intervene at level of single hole • Step 5: quality of each soldering checked by a.v. and pyrometer feedback (combination to be developed)

  4. Automated HIC assembly system from VEA Cycle time estimation • A) Worst case scenarios: • 9 chips → 9x8.1 + 8.5 + 8.5 + 9x(4x10.5) + 9x(88x10) = 8388” = ~ 2 h 20’ • 2x7 chips → 14x8.1 + 8.5 + 8.5 + 14x(4x10.5) + 14x(88x10) = 13039” = ~ 3 h 38’ • B) Normal case scenarios (soldering time/contact ~ 5 s*): • 9 chips → 9x8.1 + 8.5 + 8.5 + 9x(4x10.5) + 9x(88x5) = 4428” = ~ 1 h 14’ • 2x7 chips → 14x8.1 + 8.5 + 8.5 + 14x(4x10.5) + 14x(88x5) = 6878” = ~ 1h 55’ • * shorter time could also be possible 4

  5. Automated HIC assembly system from VEA Assuming 100 HICs for IB and 1800 HICs for OB and 8 h working day, 220 working days / year • 234 h for IB + 6540 h for OB -> 850 d -> ~ 4y • 124 h for IB + 3450 h for OB -> 450 d -> ~ 2 y
