    Reliability and Electronics Open Hour

    Present:

    Michael Naafs, Ruud Kluit, Francesco Filippini, Diego Real, David Calvo, Cedric Verilhac, Stephane Colonges

     

    -Stephane Give same news :

    ==> visit planed to Colmart, Telesub, AGE (piezzo) or Galli morelli (LOM, tipods, Su Bases, laser beacons) on march 5th and 6th (G.Roccobene, S.Colonges)

    ==> LPMI+ : New design by Rocco Masullo and AEMME company ==> new battery model (improved reliability)

     

    Discussion about PMT base:

    => No problem detected in Nikhef integration site

    ==> Michael say IPC class 3 is only in case of injury. Diego argue the need of high reliability. Stéphane said IPC 3is an added constraint to push towards AABUS procedure ==> proximity to audit is needed ==> ask to manufacture in Europe

     

    Actions decided:

    -Add A/BR coupons for microsection on the manufacturing panel ==> to be agreed with manufacturer (Action : Pasquale, Michael, Nick? and Stephane help)

    -Discuss about stackup and thickness of each layer (copper, polymid...). Sometimes thinner is better ==> check with IPC2223 rules to be coherent

    -Michael (Nikhef) evaluate the impact to move from IPC class 2 to IPC class 3. Check design rules

    -Cedric check with Daniele if all the DOM integration sites are applying the same procedure and tools for closing DOM as Nikhef. There is a plan to visit integration sites

    -Stéphane ask to Daniele : If Strain relief is applied on the rigid/flex interface? If not, actions to plan?

    -Stéphane ask to Daniele : if Octopus connector on the PMT base is glued or if there is a fixation (soldering)?

    -Stéphane ask to Daniele : Evaluate insertion force of the connector  (it is enough to avoid disconnection during DOM transportation?)

    -Stéphane Ask to pasquale a PMT base PCB to perform a micro-section analysis @ ELEMCA

    -Stephane to planify an audit in DF Elettronica ==> PCBA company for PMT base

    -Diego : missing information about Octopus CPLD gateware and about Octopus test bench (hardware/firmware) ==> send a call for new humans ressources in the collaboration to take care about that. Need also help to develop other testbenches (CLB...)

    -Stephane and Diego : Purshase before june Octopus CPLD (will be obsolete after)
