Editor's note: Get moving! Get it done! Be strict! At present, Liuyang Economic Development Zone (High-tech Zone) has carried out in-depth "three ups" competitions throughout the district. The park cadres are constantly on the move, project construction is in full swing, and enterprise production is full of firepower. open. The red net reporters walked into the park at all times and recorded the full energy and hot scenes of the park's development in various forms such as pictures, texts and animations.

Since the opening of China's first metal-based pressure-sensitive chip production line in 2019, Qitai Sensing has been constructing, producing and selling at the same time, and the current production line product yield rate has reached 95%.

"The work that Qitai does is not easy to do." Upon seeing the reporter, Wang Guoqiu, chairman and general manager of Hunan Qitai Sensing Technology Co., Ltd., "set the tone" for the company's business.

A "button-type" pressure-sensitive chip with a diameter of no more than five or six millimeters is the pain point of my country's long-term "stuck neck". How to break through foreign monopolies and keep the "core technology" firmly in our own hands? This "bad job" has been worked by the Qitai Sensing team for more than ten years.

Since the opening of the country's first metal substrate pressure-sensitive chip production line in 2019, Qitai Sensing has been constructing, producing, and selling at the same time, and the current production line product yield rate is 95%. Wang Guoqiu said that this year's performance is expected to be five times that of last year, and sales will reach 100 million yuan.

Pressure-sensitive chips are the key to pressure sensors. They can accurately convert pressure data into electrical signals and transmit them to the receiving and processing terminal. They are widely used in construction machinery, rail transit, automobiles, smart city aerospace and other fields. But for a long time, this kind of core chip technology and market have been basically monopolized by foreign companies.

The scale of Changsha's construction machinery industry is the largest in the country, and the opening of the Qitai sensor metal substrate pressure-sensitive chip production line has effectively realized the autonomy of hydraulic sensors in Changsha and even the national construction machinery industry. According to Wang Guoqiu, in April this year, Qitai Sensing has officially become a qualified supplier of leading construction machinery companies such as Sany, Zoomlion, and Sunward Intelligent. It is expected that after half a year of product testing, it will achieve larger orders in the fourth quarter. breakthrough.

Not only "liberates" the construction machinery industry, the pressure-sensitive chip of Qitai Sensing also empowers the construction of smart cities. Wang Guoqiu introduced that this year, Qitai Sensing has built a model project for pipeline safety monitoring of natural gas, fire water, and tap water in Wangcheng District, and has carried out extensive pilot projects in Liuyang townships at the same time.

“Using pressure-sensitive chips and Internet of Things technology can realize remote real-time monitoring of urban pipelines, and timely and effective early warning of pipeline accidents.” Wang Guoqiu said that the autonomy of pressure-sensitive chips provides technical support for pipeline monitoring, and he looks to the city. Since the prototype project was built, it has attracted many visitors.

Approaching the production line, a metal strip with the thickness of a little finger enters the high-precision CNC machine tool, and within a few tens of seconds, it becomes a button-shaped chip substrate. After pretreatment such as grinding and polishing, it enters the "super "Clean workshop", through many processes such as automatic sorting, cleaning, deposition, photolithography, and testing, and then packaged into sensors.

Today, Qitai Sensing's first production line is operating in an orderly manner, and the new layout plan is also steadily advancing. The second metal-based pressure-sensitive chip production line specifically developed for the new energy automobile industry is under planning.

"The park is also very supportive. Under the situation of very tight land resources, 64 acres of construction land has been prepared for us." Wang Guoqiu said that the automotive field is a large consumer of sensors. After the land is delivered, the second production line is planned for this year's National Day. Construction will be started around the festival. After the production line reaches full capacity, it will produce 30 million pressure-sensitive chips per year, and the production level will reach the industry 4.0 standard, laying the foundation for the independent control of the domestic new energy vehicle sensor field.
