Status of Hybrid Qualification and Tender
• Final Technical Specifications– Hybrid types
– Quality control, intermediate tests and inspections
– Some results on FE-Hybrids w.r.t. these criteria
• Visual inspections
• Bonding
• …
• Delivery Profile of Pre-Production
• Delivery Profile of Tender

FE-Hybrids Types
• Latest modifications in April 2003• Lamination onto ceramic stiffener
is a very critical operation• 12 different types of combinations
(the opposite of what was originally intended!!)– TIB, TOB, TEC
– 4 or 6 APV
– Connector up and down
– r and stereo ceramic (5)1 TEC, 2 TOB, 2 TIB
• APV25, positioning and bonding• Thermal cycle (simple, no bias)• Final acceptance test FHIT

Quality Control• IPC-A-600F and IPC-A-610C, class 3
• Lamination:
– detailed procedure, although recent failure is not understood.
– Crucial visual inspection of lamination after all processing steps
• Cleaning: has improved after some iterations
• APV positioning and bonding is crucial (cost driving?) element
– Certainly at limit of industrial standards
– Detailed specs for precision placement and bonding
• Dicing of APV-wafer is included as an option (1), ask for separated costing
• Trace-ability of APVs at Wafer level
• Trace-ability of individual APVs: Option (2)
• Short temperature cycle is an option (3)
• FHIT final functionality test (100%) and record for DB
