Mask Exchanges and Deadlines for A and B Semesters

The dates for cabinet exchanges can be found at the above link.   If the total number of masks submitted for use this semester does not exceed the number of mask slots available in each cabinet – the plan will be to put all masks submitted and fabricated (or already in inventory) for the semester into the first cabinet exchange, along with necessary engineering masks. A second cabinet exchange is tentatively scheduled to accommodate any changes.

All partner mask requests should be submitted to slitmasks@lbto.org.
