Quartz crystal microbalance - Wikipedia

WebA thickness shear mode crystal is supported by the edges at an approximate null or zero node to avoid interfering with the vibration. A typical 1 MHz crystal, due to its size, might be held by tension wires at several points about the surface edge. A 10 MHz unit being smaller could be supported at two points on a ceramic header. Web1) Crystal thickness The fundamental frequency is inversely proportional to the thickness, h, of the crystal disk, eq. (1). The higher the fundamental frequency, the thinner the crystal. For example, a 5 MHz QCM crystal will have a thickness of ~334 um, and a 10 MHz crystal will be half that, and have a thickness of ~167 um. rdh investments llc https://blissinmiss.com
