(Yicai) Oct. 24 -- Shares of Jinfu Technology surged after the Chinese manufacturer of battery parts and other products said its subsidiary's mass production-ready automated optical inspection testing equipment customized for Nvidia has passed the US chip giant's phased verification.

Jinfu Tech [SHE: 300128] ended 8 percent higher at CNY6.48 (91 US cents) a share today, after soaring by as much as 14.3 percent at one point. The benchmark ChiNext Index fell 1.4 percent. The stock has surged 106 percent since Sept. 18, thanks to the Nvidia partnership and the overall rally in the Chinese market.

MYZY Fixture Technology's AOI testing equipment was included in Nvidia's specification testing document for a core component of a new generation of data centers, the Suzhou-based parent firm announced late yesterday. The document will be sent to the chip maker's server original design manufacturers and cloud service providers worldwide as a guideline, it added.

AOI equipment is an important tool for inspection and process quality control and is used by electronic manufacturers to ensure product quality.

MYZY will talk with Nvidia and its ODMs and cloud service providers regarding equipment needs and orders, Jinfu Tech noted, adding that the unit will prepare to mass produce related devices.

Jinfu Technology's electronic industrial testing equipment business brought CNY231 million (USD32.5 million) in operating revenue last year, accounting for 13.3 percent of its total income, according to its annual financial report.
