Hi, Wonderful, I am trying to spin around 10 micrometer of Sylgard 184 on 1 to 2 inch glass wafers. Could you please tell me the spin parameters required to do such a thin layer of PDMS. I appreciate you comments. Thank you Seyed Quoting "Le Cao Hoai Nam": > Ditto to Brian. I always use spin-coated PDMS membranes to seal the Si > mold for my molding.
