Does your micromirror device have an anti-stiction coating applied to ease wear etc.? Bill Moffat -----Original Message----- From: mems-talk-bounces+bmoffat=yieldengineering.com@memsnet.org [mailto:mems- talk-bounces+bmoffat=yieldengineering.com@memsnet.org] On Behalf Of Youmin Wang Sent: Tuesday, August 05, 2014 7:55 PM To: General MEMS discussion Subject: [mems-talk] Wearing caused contact performance degradation for MEMS devices Dear ALL, I am currently working on the wearing caused degradation issue, for a micromirror device involving the contact of the mirror tip with the landing base, similar to a RF switch. As you may know, the contact performance, typically referring to the release voltage, degrades greatly after large amout of cycles of contact/release. I am assuming the material exchange or the surface roughness change are causing this, for which ANSYS simulation of wearing performance will shed light on the direction for the improvement. I am just wondering whether anyone of you have used ANSYS for wearing/roughness change under this topic, and do you have any comments on my idea of using ANSYS to deal with contact performance degradation? Thanks.
