The AT-cut crystal is one of the most widely used quartz crystal cuts in the frequency control industry. Its unique combination of temperature stability, broad frequency range, cost-effectiveness, and versatility makes it the preferred choice for a wide range of applications. Below is a detailed ove... read more

Crystal surface changes are a key factor contributing to aging in SC-cut crystals used in Oven Controlled Crystal Oscillators (OCXOs). These changes primarily arise from chemical, mechanical, or environmental interactions affecting the quartz crystal over time.
