When the vendor came in to install the new top heater he wasn't able to get the z-axis (elevator motor) to move. He was able to install the new heater and do a PM on the rest of the tool. We are ordering a new z-axis controller on the recommendation of the vendor. If all goes well this should solve the issue and make the bonder fully operational. I'll send out an email once the new controller has been installed. |

The YES has been giving downstream temp warnings for the RF generator. These happen on the 3000W recipes that run for more than 4-5 minutes, and are just warnings (yellow banner/light), and can just be acknowledged without notifying Staff.
