General news:

Parylene:

  • We received back our 5 modules yesterday. Demasking will start today

Reception tests:

  • Pascal + JP did all the flexes except visual inspection
  • We should receive between 9 and 18 BM from Bonn "soon" for the Paris Cluster. We should split 1/3 - 2/3 between the two lines

Gluing:

  • We should be able to try to glue everything in one week, to be planned according
  • Commissioning of new tools. Ask Thibaud about the status

Wirebonding:

  • V2 finished, all data post-wirebonding is collected but not in the PDB/LocalDB yet
    • Pull-test avg 8.7
  • PDB/LocalDB same for 63
  • New tool not yet there but should arrive before christmas
  • Old tool, wire, screws ordered
  • Joystick is showing the same issue after latest MB intervention. Not blocking but annoying.

Testing:

  • We should test the V2 done in priority
  • PPP34 is weird, maybe VMUX of FE3 is gone? Also it is rotated in LocalDB and PDB and it wasn't like this in june ... super weird.
  • PPP15 re-tested to be checked
  • PPP61 is not good, it should go back to wirebonding for inspection
  • Vacuum is installed on all 8 modules
  • Dry system filters to be changed but it's at least 1 day work

Xray:

  • New box arrived
  • We need to sum xray scans to achieve 50 hits

Wirebond protection:

  • Understand what changed on PPP34
  • Re-take the xray
