it would depend on your spinner, ambient conditions and when you'll start spinning your PDMS(if it starts to polymerize then you'll get thicker layers) but 6000rpm for 60 sec could achieve a thin layer, otherwise try to increase the speed! ---------- Initial Header ----------- >From : mems-talk-bounces@memsnet.org To : "General MEMS discussion" mems-talk@memsnet.org,"Le Cao Hoai Nam" lechnam@gmail.com Cc : Date : Fri, 22 Aug 2008 10:12:22 -0600 Subject : Re: [mems-talk] Commercial Vendors of Silicone membranes > Hi, > Wonderful, I am trying to spin around 10 micrometer of Sylgard 184 on 1 > to 2 inch glass wafers.
