      Wirebonding: 

       

      • Wirebonding play with module 6 (Wirebonding in pads not used, before doing full wirebonding): 3 short wires bonded, good pull test… but for the 17 long wired with thin pads have small pull test values
      • Wirebonding play with module 7: wire sequencing ok. Problems with wire shape and size for long wires. The CEA parameters did not work. Brigitte will get in touch with Xavier & Julien when she is back on holidays. Will also try to the pince/clip height.
      • Wire-bonders filled the spreadsheet https://docs.google.com/spreadsheets/d/1h0mClkPyKnMN8b8UpYRFYxp9Tugpk3GKiHwvpLe6dvQ/edit?usp=sharing
