Topics:

- Wirebonding

* SCC bad quality, some not usable. 3/10 observed not good, contact wurth and other for our card productions

* Metal plate out of stock

* 3x GO Quad : alignment phase, optimized parameters for bonding (8.4 g mean), not bond mod6 chip4 and mod8 chip4

* Solder type, so far used Pb

- Assembly

* Glue depositions test done. Results not obvious to understand, two values obtained, both high. To retry with new stencil / metal jig.

- Testing

* Cold setup for cycles OK and in the QC chain of the cluster
