Abstract
An improved method and apparatus is disclosed for perpendicularly mounting an AT-strip resonator on its longitudinal edge. The crystal blank is secured to the base at two or more mounting points via conductive cement which provides both electrical connection and mechanical support. A mounting cavity or slot permits proper positioning and self-fixturing during manufacture. The edge-mounting configuration promotes ease of manufacture, improved shock performance, minimized motional resistance degradation, and high packing density.
