Industry Pain Points
High-performance quartz inertial devices are widely used in aerospace and precision navigation systems. However, their packaging structure commonly relies on epoxy resin sealing, which presents critical reliability challenges:
- Repeated thermal cycling (high/low temperature) causes epoxy expansion and contraction
- Long-term stress leads to bonding failure between epoxy and substrate materials
- Gas leakage occurs due to micro-gap formation in the sealing structure
- Even minor leakage can significantly degrade measurement accuracy and stability
- Conventional detection methods are unable to identify ultra-low pressure leakage at mPa level
These issues directly affect the performance, lifespan, and reliability of aerospace-grade inertial systems.
