Abstract:

Progress is reported on a program to increase the reliability of Quartz Crystal Units CR-67U per specification SCS-237 by improvements in manufacturing techniques. These improvements will include, but not be limited to a blank cleaning, b bonding, c final plating, d curing, e sealing, f holder cleaning and g marking. The increased reliability will be demonstrated by processing 1150 crystals in five frequencies from 17 mc to 61 mc and evaluating the units in an extensive six month test program. Author
