Abstract
A fabrication procedure for crystal resonators in which belted component holders are used, each accomodating the constituent elements of a resonator. When the above-mentioned elements are assembled, the component holders serve the purpose of assembly fixtures. The assembled resonators are retained in the component holders which thus also provide a packaging function for the final products. The component holders have elastically deformable clamps which accomodate the constituent elements of the resonators to be assembled and have support sections which receive the crystal element of each resonator.
