Meeting ID: 839 4223 4865
Passcode: 503560

• Schedule update
  • Global schedule
    • 7/1-- Launch "Our shift system" for Fuji B4.
    • 7/16-- Launch Bare PCB QC for production in our current estimate - fingers-crossed.
       
  • Two task lines for the weeks of 7/1 and 7/8.
    (1) Reception QC line: Populated PCB QC after HV/LV-setup fix (to be assembled with ITkPixv2)
    (2) V2 module assembly QC and R&D line: ITkPixv2-related QC after PC fix (for core column issue)
    
    
• Shift update accordingly
  • For the weeks of 7/1 and 7/8: As scheduled for Mon-Wed. If the existing components are all tested, may cancel shifts for Thu-Fri.
  • From the week of 7/16: Further updates to be informed by 7/8 at latest. 
  • Details in the shift table 
    

 

• Items to be sorted out before production
  • Items in red needs immediate actions 
  • Items in orange should be addressed next week 
  • Initial list with our actions & priorities in the spreadsheet. More to be added via further rehearsal by several people from next week.
    
    

 

• Metrology machine scan speed up in BM QC
  • Initial implementation already done by Sugawara san -> BM Flatness+height 38->16min.
  • Mitigation proposals were presented by Aoki san, also considering which variables are stored in DB.  
  • Some of the proposals will be tried next week, while keeping the necessary presicions.
     
• HV/LV automation
  • Ikegami san already established window-based system with several updates e.g. catch the connection error first and apply HV/LV automatically.
  • Kumayama will address to update the output-line format in result csv file.
    
    
• Next meeting next week or maybe in two weeks

 

17:00 → 17:05 Introduction

Goal: Establish the procedure and tools of each QC step of FLEX/BareModule Reception --> Mostly done! Congratulations!
Next goal: Commission Fuji QC effort as shifts and run it sustainably to meet the assembly schedule.

New items at this meeting:
--- Production schedule update (Nakamura)
--- Shift confirmation (including partial cancellation) for July and August (Nakahama, Ikegami)

--- 量産QCに向けて、足りていない部分の確認、気になることの頭出し (all)
https://cernbox.cern.ch/s/xHDGXUiOsE4y2ZD
Initial list by Nakahama & Ikegami. Please add your inputs if you have in mind

Follow up items from the previous meeting:
--- Confirmation on data upload readiness for v2 modules
--> Mostly ready
--- Upload old QC test results to LocalDB?
o v1.1 10 + v2 6 and 10 additional modules as IV failure in prepro replacements
o 130 preproduction
Either use script for data upload or web interface?

--- Re-review of time reduction of Fuji QC menu (Ikegami (LV/HV), Sugawara & Nakamura (metrology, IV), ...)

--> Thanks all for the efforts!
(最新実測metro) BM 35min, PCB Reception 29min, PCB Population 14min (設置時間抜き) 2024/06/21
QC全部で、BMは60min, PCB receptionとpopulationはそれぞれ 30min

Please write down the update either in the slides or minutes for record.

【ミーティング後メモ】(sugawara)

• height→来週測定点調整＋解析結果比較して改善させる
• back sizeいらない、なくす
• front heightなくしてsize少し増やす？
• front flatness求められてないけど、frontとれるのはBMだけだから欲しい
