Abstract: This paper introduces the structure and principle of a surface-mount high-precision temperature compensation crystal oscillator, and specifically describes the reliability design of a quartz-crystal resonator used inside the surface-mount temperature compensation crystal oscillator, the reliability design of surface-mount ceramic base and the reliability design of hybrid micro-assembly. Finally, the thermal and mechanical simulation results and the experimental verification of this surface-mount temperature compensation crystal oscillator are provided, which prove that this crystal oscillator has high reliability.

Key words: temperature compensation crystal oscillator (TCXO), high precision, reliability
