As the sensor is gradually miniaturized and miniaturized, the processing technology of the sensor is changing gradually. Therefore, in order to develop a sensor with high accuracy and high stability, a complete and effective manufacturing process must be set up. In the production of previous sensors, the traditional processes often have large deformation, which can easily damage the internal components, low machining precision, and the stability is not strong. In view of these, laser optical laser combined with the processing characteristics of the sensor industry, innovative for the sensor enterprises to provide a professional laser solution. This scheme overcomes the traditional process of large deformation, the problem is easy to damage the internal components, has the characteristics of high precision, stable performance, easy to realize automation, especially suitable for the precision machining of the sensor, at present in many domestic and foreign manufacturers are using sensors.
