YES Polyimide Bake Oven

Oven for curing polyimide and other polymer films

YES Polymide Bake Oven Backup: Michael Skvarla


The 450PB is a high temperature vacuum oven using a programmable temperature controller and programmed vacuum and nitrogen flow cycles for curing of polyimide films. The unit features filtered heated nitrogen purging from the entire surface of the roof through the floor of the chamber. This flow acts to clean the wafers during the process.

Many thanks to Yield Engineering Systems (YES) for improved controller parameters leading to better temperature control.
