The shaft that actuates the isolation valve between the loadlock and the process chamber has broken. I have reached out to Plasmatherm to see if they happen to have a spare but the odds are exceedingly low. We will update you all as we know more, but it will be down through the weekend and into early next week. |

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. |

I will send out an update once we have one. |
