Hi Darren, I never used glass as substrate before, so really do not know what will be the case. But it will never hurt to give it a try. My suggestion is to clean your glass really well before spinning would help prevent the PI peeling off during the fabrication. If anybody else has such experience to share with, that will be really helpful.

Any idea about polyimide to glass? Does that work the same way. In essence I just need some rigid substrate to start of with. > > Cheers, > Darren
