General news:

  • We are asked to perform flatness measurements pre-post thermal cycled to verify deformations WITH canopies on
  • We received (IJCLab) components to assemble digital quads
  • We will receive 6 Advafab-HPK (Winstek) V2 bare modules (+ flexes)
  • CERN clean room will close during the summer for 2 weeks, to be careful about timing
