I’ve completed the installation of the new spool and lamps and the tool is free to use. We’ve run a number of different etches and upon initial inspection everything looks normal. However, it’s recommended you start with a test etch in case there is a slight shift in process. |

Due to a DDoS attack affecting the Signupmonkey server, we have restricted access to the website, including both the Nanofab Wiki and Signupmonkey, except for users '''on campus using UCSB Wi-Fi or LAN'''. |

If you are off-campus, please utilize the UCSB VPN to access our sites. Here are the installation instructions for VPN on your device. You will need your UCSB NetID for download and installation - you would have received a UCSB NetID when you started using the NanoFab: |

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 error has been cleared and I ran a shorter 5 minute recipe with no warning/error. |

This seems to be exclusive to the longer (8+ minute recipes), which are throwing warnings for every wafer run this long. It also appears that running 3 wafers on a longer recipe will result in an error and aborted run on the 3rd wafer. We are just going to have to live with this until we have our other generator back. So until then, please limit the longer runs to 2 wafers max. If you have more than 2 wafers to run on a longer recipe then wait about 5-10 minutes in between batches. |

We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests. |

EVG - Scheduled downtime
I am looking at sending that generator on the week of March 24th or 31st. It should not take that long, but I would plan for it to be down for 3 weeks.
Please let me know if this does not work for you or if you prefer one week over the other.

The board we were waiting on arrived, but it did not resolve the tool issue. We are working with Panasonic on the next steps. //Vraj Mehalana 14:17, 1 March 2024 (PST)
