China Moneypro Low-Pressure Testing Component

Industry Pain Points

n

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:

n
n

n
• Repeated thermal cycling (high/low temperature) causes epoxy expansion and contraction

n

• Long-term stress leads to bonding failure between epoxy and substrate materials

n

• Gas leakage occurs due to micro-gap formation in the sealing structure

n

• Even minor leakage can significantly degrade measurement accuracy and stability

n

• Conventional detection methods are unable to identify ultra-low pressure leakage at mPa level

n

n

These issues directly affect the performance, lifespan, and reliability of aerospace-grade inertial systems.
