Both fan-ins in LINK1 has been replaced to solve the shortcircuits we had bue to bonding problems. Unfortunately in the rebonding process, the bond head went down without control. The tool crashed against one fan-in making a crater, and the clamp destroyed the master chip on link1. We don't know if it was a stop switch malfunctioning or a bug in the bonder microcode.
After cleaning the area, unbond the master chip, change the bonder tool and check the machine, we succeeded in bonding the other chips in link1.
No optical readout is used, we use the electrical lines.
