On November 27, Glonghui reported that Guanghe Technology (001389.SZ) stated on the investor interaction platform that, upon verification, Mr. Wang Jun, the company's vice president, mentioned in a related interview that the company's server PCB products have passed certain product certifications for the nvidia GB200 chip. This indicates that the company's relevant AI server PCB products have been certified by downstream ODM customers and are still in the R&D and sample production stage. Currently, most AI server PCB products on the market use nvidia GPUs, but not all AI server PCB products need to obtain nvidia's 'manufacturing authorization'; as long as the customers comply with market policies and terms, it is sufficient. The company has not yet passed nvidia's customer certification, and investors are advised to pay attention to investment risks and avoid blindly following hot trends.
