Partecipants: L3 students, Matteo, Piero, Yann, Stephanie, Thiziri, Giovanni, Paul, Francesco, Yahya, Reina, Pascal, Julien, Marc

General news:

• Column to be masked are more frequent on the flex-mounted modules instead of SCC. Maybe ESD?
  • It is possible to make an analysis from the PDB.
• Flex PRR but without circulating information
• Review to buy the wafers of V2 soon 

Wirebonding:

• Ball bonding head was OK until friday
• Wedge re-installed on friday but not operational. Many bugs. Investigating with MB. Intervention from MB tomorrow.
• We will try to unplug it today and power it again tomorrow
• Maintenance in february week of 19

Assembly/Metrology:

• Confocal led working. A bit noisy but the expert is not worried.
• Confirmed that we can make the planarity measurement with the confocal led but the planarity tool is not flat enough.
  • We can try to flatten it in the lab? To be investigated

Testing:

• Significant speedup on the analog readback measurements
  • Electric test is 3h30 with the old version
    • 2h15 with the new version
    • Parallelism demonstrated to have little impact
  • Digital 30m
• We need to produce a second unit to test 2x module parallelism
• DCS OK, dew point calculation on KD board implemented
  • Temperature 8x modules
  • SHT85
  • Pression 2x
  • Dew point calculated with own temp using SHT85 up to -40 C then using chamber temperature
• Interlock board firmware updated, card to be reinstalled tomorrow

Xray:

• It works. To be correctly estimated in terms of time
• Meeting next week 31/1 to decide how to install
