Mike, This method sounds interesting. Can you elaborate more on this method (e.g. UV wavelength and power, specialized equipment required, etc.) or provide a reference? Thanks, Lee Pang wpang@ucsd.edu -----Original Message----- From: mbeggans@biovalve.net Subject: [mems-talk] PDMS bonding to glass UV/Ozone clean for ~ 1min or so and immediately contact the PDMS and glass. It's not a permanent bond (you can peel the PDMS off afterwards). It will hold up to high pressures (as in a microfluid channel), but not high shear stresses.
