QUARTZ CRYSTAL AGING EFFECTS.
Abstract
Aging studies of about 300 quartz resonators in the frequency range 81.9 kHz to 30.0 MHz stored at 85C were made. Frequency measurements of one group of 10 MHz units stored at 125C were performed. The 3 MHz units with conventional electrodes and the 5 MHz units with both conventional and annular electrodes were mounted and sealed in HC-27/U glass holders. In addition, approximately 35 units were mounted in holders sealed by cold welding. Frequency spectra and x-ray topographic analyses were made of units plated with conventional and with annular electrodes. (Author)
