Development of minitype long life quartz crystal oscillators

With the system to an integrated, modularization and long-life development, quartz crystal oscillator miniaturization, long life have become increasingly demanding. We wish to develop a new quartz crystal oscillators without the conductive epoxy to eliminate the change issues of crystal chip bonding material. First, it is required to develop small long life quartz crystal oscillator design, to solve the equivalent resistance and input current issues and to eliminate the change issues of crystal chip bonding material. Then the design is verified through the production of crystal samples and testing - a number of typical crystal frequency oscillators are developed. Compared with the common crystal oscillators the frequency-temperature stability and input current are consistent, and the change issues of crystal chip bonding material-conductive epoxy die has been completely eliminated in the 32 older long life and the minitype long life quartz crystal oscillator technology has been realized.
