Greetings Not knownig the size of your crystals.one way use the crystal fixture/ holder used in vacuum systems. The limitation 0.55 inches The crystals can be removed at will. Or maybe you can machine a larger fixture using the priciple Regards Walter www.elume.com -----Original Message----- From: erkin seker [mailto:erkin@virginia.edu] Sent: Wednesday, October 26, 2005 8:41 AM To: General MEMS discussion Subject: [mems-talk] Quartz Crystal Fixture Hi, I am doing experiments with quartz crystal microbalances. I need a fixture that I can easily install and remove the crystal without soldering or bonding with epoxy. I will be doing consecutive resonant frequency tests, and I want to minimize the effect of fixture on measurements. Is anybody aware of such a fixture?
