Recently, Wuhan Eternal Technologies Co., Ltd.,(ETERNAL) officially completed a new round of financing worth hundreds of millions of RMB. This round of financing was participated by well-known investment institutions such as Legend Capital and additional contributions from existing shareholders. This marks another significant capital injection for Yitiannuo within the year, following its Series A financing in April 2026. It signifies that the company's industrial value in the field of optoelectronic integrated precision testing and packaging has been highly recognized by leading capital institutions.

Testing and packaging equipment have become the key to industrial success

The year 2026 is widely regarded by the industry as the inaugural year for the industrialization of Co-Packaged Optics (CPO). Global technology giants are collaborating with unprecedented synergy to propel optical interconnects from being an "optional solution" to becoming a "mandatory architecture".

However, apart from chip design itself, testing and packaging are even more crucial bottlenecks in the industrialization process, impeding the scaling up of products.

As transmission rates leap from 400G to 800G and 1.6T, and as packaging architectures evolve from pluggable to co-packaging, the focus of testing and packaging is significantly shifting from traditional "module-level finished product testing" to "wafer-level packaging transfer and in-line testing". Nanometer-level alignment accuracy, multi-channel parallel measurement, high-throughput reliability screening, and high-density FA coupling packaging—these technical indicators directly determine mass production yield and delivery costs.

This is precisely the field in which Eternal Sky is positioned, and it is also the industrial opportunity targeted by the current round of hundreds of millions of yuan in financing.

Capital consensus, deeply cultivating the "new infrastructure" of industries

Legend Capital, with a deep-rooted expertise in equity investment spanning 25 years, has chosen to invest heavily in Yitiannuo in the field of optoelectronic integration testing, reflecting a profound assessment of industry trends and the company's competitiveness.

From an industry perspective, optoelectronic integration testing and packaging equipment pose extremely high technical barriers—it requires teams to be proficient in optics, precision machinery, automatic control algorithms, AI model image recognition, and semiconductor processes simultaneously. Any shortcomings in any of these dimensions will lead to a cask effect on the overall performance of the equipment. Globally, there are only a handful of players capable of providing mass production-level optoelectronic integration packaging and testing equipment.

The injection of capital will accelerate Yitiannuo's crucial leap from "leading in equipment" to "leading in production capacity".

The tide of optoelectronic integration industry has already surged.

From silicon photonic chips to CPO packaging, from 1.6T optical modules to hetero-integration architectures, each technological breakthrough is underpinned by precise and sophisticated measurement and testing equipment.

Yitiannuo has chosen a path that is extremely challenging yet holds long-term value—to be the one deep within the industrial chain, providing a verification benchmark for every technological iteration.

The injection of hundreds of millions of yuan in capital represents not only recognition but also responsibility!

Yitiannuo will take this as a new starting point, leveraging technological innovation as its driving force and industrial empowerment as its mission, to continuously delve into the field of optoelectronic integration packaging and testing. Together with all industry peers, we will jointly write a new chapter of "Light Driving the Future".
