Bonding should occur immediately.
However, I find the process very unreproducible so if anyone has any
tips to improve the chances of success please let us know.
Last week I managed to get very good bonding without any problems but
yesterday it no longer worked.
I use a PlasmaPrep II Plasma Etcher from SPI. This unit doesn't provide
much control over the plasma conditions which may be part of the problem.
What is the best way to prepare the surface of the glass?
I also wonder if it is important to ensure the PDMS is thoroughly cured
prior to bonding?
Best regards
