Speakers: James Julian Glover (University of Birmingham (UK)), Jian Liu (University of Liverpool), Marcello Borri (staff@stfc.ac.uk)

Prototyping jigs

• The drawings and step files are with the Liverpool workshop
  • Some tolerances are still under discussion 
• The manufacturing takes about 20 - 25 days; expected to start sometime in January 

Module test rig

• Oxford is designing the 3D printed carrier plate/jig

Wire-bonding on the foils

• Comparative tests ongoing
  • With and without acetone cleaning 
  • A softer bonding wire

Dummy FPC 

• The design for module assembly will happen in the coming weeks

Dummy silicon

• Dummy AncASIC (500-600 chips): quotation in October, about 10 kGBP (excluding VAT)
