Abstract : RESONATORS ARE REVIEWED WITH EMPHASIS ON THOSE ASPECTS WHICH CAN BE INFLUENCED BY THE RESONATOR'S PACKAGING. A microcircuit compatible ceramic package design is proposed which is aimed toward optimizing the performance of quartz resonators. The package consists of a frame with a top and a bottom lid. The crystals are mounted in metal clips which are initially highly flexible. After mounting, the clips are strengthened as necessary by electroplating. The package parts can be baked at high temperatures, and are hermetically sealable in ultrahigh vacuum, at room temperature, without the use of large forces. The sealing process relies on the adhesion between atomically clean surfaces. The package is adaptable to sealing in inert atmospheres by alternate techniques. (Author)
