Jingcun Technology received Pre-IPO round of financing to accelerate the localization of storage chips​


According to Shangqi Capital, Shenzhen Jingcun Technology Co., Ltd. ("Jingcun Technology") recently announced the completion of its Pre-IPO round of financing. The financing was led by Shangqi Capital, followed by Rongyi Capital, Hefei Construction Investment, Xingzheng Capital, Yishan Investment and other institutions. The specific amount of financing was not disclosed. The funds will be used to further promote the company's technology research and development and market expansion.
Founded in 2016, Jingcun Technology is a national high-tech enterprise integrating design, R&D, testing and sales of storage chips. It owns consumer-grade storage brands and high-end automotive and industrial storage brands. Jingcun's subsidiary Miaocun Technology has flash memory controller chip R&D capabilities and firmware development capabilities, and is a national "specialized, sophisticated and innovative" small giant enterprise. Jingcun has complete storage solution capabilities and has its own brand Rayson. Its products include NAND FLASH controller chips, eMMC, UFS, DDR3/4, LPDDR4/4X, LPDDR5/5X, eMCP, UMCP, SSD, etc., covering consumer-grade, industrial-grade, and automotive-grade storage chips, which are widely used in mobile phones, tablets, notebooks, educational electronics, Android boxes, smart terminals, smart homes, Internet of Things, smart medical care, industrial control equipment, automotive electronics and other market fields.
Shangqi Capital pointed out that Jingcun Technology is one of the few storage module manufacturers in China that can achieve national localization of "wafer + main control + module", and is in an industry-leading position in the field of embedded memory modules and flash memory main control. The company has the independent research and development capabilities of main control chips, which are rare among module manufacturers, and is in a technologically leading position in the field of domestic automotive-grade UFS main control chips. In the future, the company is expected to achieve localization substitution of automotive-grade memory, thereby playing an important role in ensuring supply chain security.​

Techinsights analysis on the S11134A L-PAMiD used on Huawei Mate 60 pro.

They found that:

The S11134A is still a 2019 design

The Integration level is not high,there is too many standalone components,result in the much larger overall size of the module compare to others

No BAW or FBAR filter found in the module,all 8 filters inside are SAW filter,indicates that Chinese BAW/FBAR technology still not mature

The SAW filter is made of low end material

The packaging tech used is the standard 2D packaging ,not that advanced

If this L-PAMiD is China's most advanced L-PAMiD,then China is at least 5 years behind the top 5 industry leaders in this field(Murata,Qualcomm ,Broadcom,Qorvo,Skyworks)

That's a lot of criticism for RF system that vastly outperformed iPhone.

They keep talking about what's more "advanced". But in the end, performance matters and the latest Mate 70 RF is clearly far ahead of everyone else. This is validated in actual usage.

Whatever Huawei did was clearly chasing for actual performance over what "Western experts" consider to be "advanced".

Domestic Spectrometers for ICP/CCP etching equipment.

The OES detection system can use the Jianzhi Technology SR100Q spectrometer, which has the following main advantages: wide wavelength range, covering the UV-visible-near infrared band, high resolution, low spurious, high sensitivity, low noise, high signal-to-noise ratio, easy software integration, high-speed testing, and customized spectrometers according to needs, with anti-aging optical fiber and cosine corrector to build a monitoring system. The window of the etcher reaction chamber, through which the cosine corrector collects the plasma spectrum in the reaction chamber, transmits it to the spectrometer via optical fiber for signal processing, and finally outputs the monitoring spectrum for analysis.

5. Application Examples and Advantages


Examples of fiber optic spectrometer applications during plasma etching include, but are not limited to:

1. Real-time monitoring of changes in plasma temperature, density and chemical composition to ensure the stability and consistency of the etching process.

2. Identify and control harmful components in plasma to reduce environmental pollution and equipment corrosion.

3. Optimize etching process parameters to improve etching efficiency and quality.

Jianzhi Technology provides fiber optic spectrometers with different performances. Its advantages in the plasma etching process lie in its high resolution, high sensitivity and real-time monitoring capabilities, which can provide engineers with accurate and reliable plasma parameter information, thereby optimizing the etching process and improving product quality and production efficiency.​

Do we know whether the Mate 70 RF is the same as on the Mate 60 or has it been upgraded significantly?

Well, we think Mate 70 RF is significantly upgrade, but even Mate 60 was tested to have better download/upload than iPhone.

I don't know what Mate 70 RF will look like, but they are clearly chasing for real world performance vs higher integration of modules.
