A process is described for the fabrication of CR-XM-23U quartz crystal units in the range of 50 to 100 Megacycles. No special changes in the normal production techniques were required although many refinements in existing procedures were found necessary to get acceptable yields. A few special tools were developed that proved to be very helpful in producing the pilot run. Details of both refined techniques and tooling are discussed. Problems of especial importance that arose include 1 controlling flatness of the finished blank, 2 polishing the quartz blanks, 3 base plating, and 4 sealing the HC-18U crystal holder. Author
