27 Apr 2005CMS TrackerWeek - Module Production10 Salvatore Costa - Catania 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 Module list

CMS Tracker Week, CERN, April Apr 2005CMS TrackerWeek - Module ProductionSalvatore Costa - Catania Selected highlights from individual Center Reports

27 Apr 2005CMS TrackerWeek - Module Production14 Salvatore Costa - Catania Catania: new facilities New bonding machine: Delvotec 6400 (100 kHz) –Since March 8 th –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 –2 nd operator fully trained since last meeting already. –3 rd operator: Russian engineer with temporary contract.

27 Apr 2005CMS TrackerWeek - Module Production15 Salvatore Costa - Catania Catania’s Delvotec 6400

27 Apr 2005CMS TrackerWeek - Module Production16 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 2 nd 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.
