According to a recent report by CCTV Finance, its "Specialized, Specialized and New Manufacturing Power" series reported on Shenzhen Zhongtu Instrument Co., Ltd. The company has spent 18 years carefully polishing 15 hard-core technology "rulers", from nanometers to hundreds of meters, from contact to non-contact, and continues to expand the full-size chain in the field of industrial measurement.
According to company chairman Ma Junjie,The microscopic measuring instrument manufactured by his company has a resolution of 0.1 nanometers.It has been widely used in the semiconductor field and can directly measure chips.
For example, a seemingly smooth wafer still looks patchy on the surface under a microscopic measuring instrument. After measurement, the height difference is only 6.1 nanometers, but it still needs to be cut into smaller squares before it can be used.
In addition, the flash tester produced by their company has very fast measurement speed.It only takes a few seconds for a precision structural part on his mobile phone to directly display hundreds of dimensions with micron-level accuracy.
In addition to micro structural parts, their team can also measure giant industrial workpieces. The laser tracker they developed can measure hundreds of meters in size. It is the only high-performance optoelectronic instrument that has both micron-level measurement accuracy and a working space of 100 meters.
It is reported that Ma Junjie graduated from Tsinghua University majoring in precision instruments. While working in a research institute, he discovered that all the precision instruments in the laboratory came from abroad, which gave him the idea of starting a business to make domestic geometric measuring instruments.
Although their company has only produced 15 measuring instruments in the past 18 years, each one has its own characteristics and can solve the measurement pain points in industrial production.
