According to the latest report released by the market research institute, the global sensor market is expected to reach $128.56 billion by 2025. From the perspective of application fields, automotive electronics, consumer industry, communication electronics, electronics occupy the largest market for sensors at home and abroad, and the largest proportion of sensors in the industrial and automotive electronics industries. Domestic sensor technology is at a critical stage of innovation and breakthrough, and reflects the new trend of miniaturization, multi-function, integration, digitalization, systematization, intelligence and network development.

With the development of laser technology and automation technology and the mature application of sensor production and processing technology, domestic and foreign enterprises that master the core technology of laser welding play a major role in further solving the problems of low accuracy and poor stability of the traditional process of sensors. The principle of the sensor is not difficult, and it is not secret, and the secret is the processing technology.

Laser welding

Sensor technology, together with computer technology and communication technology, is called the three pillars of information technology, and has an extremely important strategic position. In recent years, the domestic and foreign sensor market has developed rapidly, but there is still a gap between domestic sensor technology and the world level, at present, many domestic enterprises to increase technology research and development efforts to seize the high-end market.

Sensor production process is introduced

The traditional packaging welding of sensors is mainly realized in the form of argon arc welding and semi-automatic laser welding. Due to the high heat of argon arc welding, it is very easy to adversely affect the performance of the chip inside the sensor, so it is gradually replaced by laser welding.

Laser sensor laser welding packaging process, mainly through the sensor laser welding equipment and automation technology solutions to achieve. Product automatic welding, the entire welding packaging process through the system automatic completion, to achieve the free and fast conversion of each formula, the system to complete the welding function, welding position accurate adjustment.

Laser welding machine adopts non-contact laser wire feeding welding, which can effectively avoid welding mechanical damage; At the same time, the spot size of the welding equipment can be automatically adjusted, which can be applied to various types of solder joints to meet the needs of more products.
