Andrew: bFPC test jig to allow testing bFPC-sensor assembly before mounting to mFPC

6 Update on IB related activity

Speakers: Andrew Hill (staff@stfc.ac.uk), Laura Gonella (INFN Trieste)

Andrew: 6 mock-ups for mechanical characterization, made with Cu, 3 flexes. Plate-through-holes (CERN) vs tabBonding (LTU).

Laura: Trieste will receive ITS3 FPC prototypes from CERN and will do FPC characterization,

7 Further brainstorming
