Global review of Module bonding quality
that is,

Hybrid-related issues
1. Bonding problems on PA encountered while bonding APV’s to PA in some TIB hybrids [mentioned by Alan/Gabriella]
Display additional warning in Pre-bonding section of DB Interface
• Faulty hybrids, with intermittent FHIT errors, erroneously sent to CERN from HAS, then to Gantry Centers and some already built into modules. [mentioned by Gabriella]
All Gantry and Bonding/Testing Centers alerted I plan to generate from DB and distribute affected

We are continuing to monitor the preparation of attidional jigs for Center backup in TEC.
This is a table already showed at last Meeting, but with updates added yesterday.

Selected highlights from
individual Center Reports
27 Apr 2005CMS TrackerWeek - Module Production 14 Salvatore Costa - Catania
Catania: new facilities• New bonding machine: Delvotec 6400 (100 kHz)
– Since March 8th
– Oldest of 2 Hughes dismissed– Now in clean room: Delvotec, newest of 2 Hughes– Bonding times down:
• TIB34: 8’ 10” vs. 45’ + x• TIB12: 12’ 15” vs. 65’ + x• Backs: 15” vs. 1’ + x
– Reliability improved:• Machine failure rate: negligible• Bonding failures: negligible• PHL- (DEAD) channels: none so far
– Experience:• 45 modules bonded w/ new machine• Programs for all module types ready: TIB34, TIB12, TIB12sl, TIB12sr (back/front/pulltest/after_pulltest)
– Usable bonding parameters window narrower than in Hughes– Best Pull forces achieved: ~10g
• New operators– 2nd operator fully trained since last meeting already.– 3rd operator: Russian engineer with temporary contract.

Catania’s Delvotec 6400
27 Apr 2005CMS TrackerWeek - Module Production 16 Salvatore Costa - Catania
Other Center’s highlights• FNAL: Last 2 weeks found problems related to excessive flex of PA
ends. Had to ask assemblers to move glue points. This helped but not yet satisfactory.
• Firenze: In some latest TIB modules dirty area of PA near end (but not at end) made bond difficult there.
• Padova: Uploaded pull test data after shipping modules to Pisa usual DB problem: pull test appears performed in Pisa
recommendation: upload all of your data before shipping modules to another center
• Torino: Due to share with Alice had to change Delvotec’s U/S frequency from 100 to 60 kHz. New parameters. Similar performance.
• Vienna: Bonded 25 modules with new Delvotec 6400 (140 kHz). Pull forces were marginally better than 100kHz. Observes whiskers on 2nd bond (on PA).
• Zurich: Machines now equipped with additional USB camera (+ PC) to ease the strain of looking all the time through microscope during bonding. Model details available.
