Plasma cleaner: 2 & 3

Plasma Cleaner:2 is located in PolyFabLab, and Plasma Cleaner: 3 is located in the PDMS lab in building 347.

Plasma cleaner 2 : SurfacePrep(located in PolyFaLab) and Plasma cleaner 3 : PDMS (located in PDMS lab) are Diener Atto (PC control, 13.56 MHz RF) systems installed in 2026.

The Plasma Cleaner 2 : SurfacePrep can be used for the following processes:

• Fine cleaning/surface activation of polymer parts prior to bonding, coating, printing
• Photoresist stripping
• Descumming
• Surface cleaning

The user manual, and contact information for plasma cleaner : 2 can be found in LabManager - requires login

The Plasma Cleaner 3 : PDMS can be used for the following processes:

• Surface activation and micro-etching of cured PDMS surface
• PDMS to glass bonding

For further information about PDMS to glass bonding follow the link: PDMS Casting

The user manual, and contact information for plasma cleaner : 3 can be found in LabManager - requires login
