Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensor packaging, in particular to a glass-filled device for reducing thermal expansion of silicone oil. Background Art

[0002] As an important sensor, pressure sensor is widely used in various fields. Common pressure sensors are divided into foil pressure sensors and MEMS pressure sensors. Among them, MEMS sensors are smaller in size and more sensitive, and are the future development direction. However, silicone oil is generally used as the pressure transmission medium inside the pressure sensor. Since silicone oil is a liquid with a large thermal expansion coefficient, the sensor sensitivity becomes low, the response speed becomes slow, and it is easily affected by temperature changes. If the glass is made into a shape that matches the inner cavity of the tube seat and fixed in the tube seat of the pressure sensor with an adhesive to reduce the filling amount of silicone oil, the thermal expansion coefficient will be reduced and the temperature performance of the pressure sensor will be more stable. However, when the glass is bonded to the inside of the tube seat of the pressure sensor, the staff manually takes tweezers to clamp the glass of the corresponding specifications and shape and applies adhesive on its surface, and then fixes the glass to the inside of the tube seat. Although the operation is convenient, the efficiency is low. To this end, we propose a device for filling glass to reduce the thermal expansion of silicone oil. Utility Model Content
