This paper deals with design and simulation of vibratory ring gyroscope which has good performance as resisting vibration, resisting impact, small temperature drift because of the inherent symmetry of structure. The good performance of gyroscope has verified by detailed modeling and simulation. The manufacture of gyroscope using wafer level vacuum packaging technology making the gyroscope has high quality factor .At last we test the gyroscope and the Q factor is 20300 by detecting the resonant state of the gyroscope.

Slip Ring

Due to its specific structural features, the packaging technology is quite essential for the conductive slip-ring (CSR) encapsulating with epoxy molding compounds (EMC). In this work, a modified vacuum packaging technology has been proposed which includes a pouring process and a followed soaking process. Based on the experimental results; the reliability of the CSR packaged obtains a significant improvement as its thermal stability and electric insulating property are obviously advanced, comparing with that fabricated by the normal vacuum packaging method.

Slip Ring

Based on its specific structural features, the packaging technology is extraordinary significant for the conductive slip-ring (CSR) encapsulating with epoxy molding compounds (EMC). In this work, a modified vacuum packaging technology has been proposed which includes a pouring process.By the construction of the relevant models, the packaging technology was calculated by MATLAB and discussed. It indicates that the EMC can be easily poured into the concentric ring slit of the CSR only with a differential pressure of 200 Pa between the outside pressure and the inside pressure. On the bases of the experimental results; the EMC can easily flow up from the bottom to the top of the CSR packaging mold vertically.

Slip Ring

Due to its specific structural features, the packaging technology is extraordinary significant for the conductive slip-ring (CSR) encapsulating with epoxy molding compounds (EMC). In this work, a modified vacuum packaging technology was put forward for which includes a soaking process.By the construction of the soaking models, the packaging technology was calculated by MATLAB and discussed. The soaking model reveals that the soaking time is strongly influenced by the space of the exhaust vent and the added pressure. When the soaking pressure is set at 6 atm with the vent of 0.02 mm width, the EMC can be completely soaked into the tiny spaces of the CSR in 5 min.
