New Gowns: Toolbelts purchases

We are required to switch to new gowns in January. The new gowns won’t have pockets, but you are allowed to purchase cleanroom tool belts. Please ask staff for which tool belts you can purchase.

Two vendors for cleanroom belts we are using are listed here, you may request others:

Suss SB6-8E

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.

I will send out an update once we have one. -Aidan // Demis D. John 00:35, 8 December 2024 (UTC)

ICP1 Down

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)
