36Kr learned that Shenzhen Guoaokeji Co., Ltd. (hereinafter referred to as "Guoaokeji") recently announced the completion of tens of millions of yuan in Series A financing. This round of financing was invested by Shenzhen Capital Group, and the funds will be mainly used to expand production capacity and accelerate product R & D in fields such as high - end semiconductors, automobiles, and robots.

Founded in 2018, "Guoaokeji" is a high - tech enterprise focusing on the R & D and manufacturing of multi - degree - of - freedom precision motors. It is committed to providing high - precision motion control solutions for fields such as semiconductor equipment and precision automation. In 2024, it was recognized as a specialized, refined, distinctive, and innovative small and medium - sized enterprise in Shenzhen.

The "integrated linear - rotary motor" independently developed by "Guoaokeji" can achieve two - degree - of - freedom micro - nano positioning and soft - landing function, with precise force control up to ± 0.01N. It can be applied in fields such as advanced semiconductor packaging, high - precision measurement, 3C, opto - acoustic - electrical precision mounting, collaborative and humanoid robots. Many of its products have been adopted by leading semiconductor and 3C manufacturers.

I. Seize the trend of domestic substitution of semiconductor equipment, and self - developed high - precision motors have supplied goods to many leading customers

In high - end manufacturing fields such as semiconductors, motors are the key to the efficient and stable operation of various precision manufacturing equipment. Through high - precision motion control, precision motors can achieve micron - or even sub - micron - level positioning and dynamic adjustment, ensuring the precise execution of complex manufacturing processes. For example, in the process of semiconductor chip mounting, the motor can achieve precise picking and placing of chips, ensuring the yield rate of chip manufacturing.

Dr. Li Siyang, the founder of "Guoaokeji", graduated from The Hong Kong Polytechnic University, with a research direction in multi - degree - of - freedom motors. He founded "Guoaokeji" right after graduation, hoping to apply his research theory in practical applications.

The general trend of domestic substitution of semiconductor equipment has given "Guoaokeji" an opportunity to enter the market. In Li Siyang's view, semiconductor equipment has several relatively key requirements - fast, accurate, and stable. Physically, these requirements interact with each other and are even contradictory, forming an "impossible triangle". The gap between traditional domestic equipment and imported equipment lies in the difficulty of balancing these indicators. Often, compromises have to be made on one of the indicators and the standards have to be lowered.

Based on the new theory of multi - degree - of - freedom motors, "Guoaokeji" designed a brand - new technical solution. Traditional motors have one mover and one stator, and can only perform one - dimensional motion, either rotation or linear motion. The motor of "Guoaokeji" can perform two - axis motion with one mover, which can both rotate and move linearly. "When linear and rotary motions are simultaneously realized in one motor, our execution accuracy will be higher. Moreover, there is no mechanical transmission in our motor. All mechanical connections adopt direct - drive transmission methods, and the speed, rhythm, and force of motion are controlled through magnetic field changes." Li Siyang summarized.

Of course, no matter how advanced the technical solution is, it still needs to be verified in actual application scenarios. Especially in the field of semiconductor equipment, secondary development is often required based on customer feedback. During the application R & D process, several leading customers provided sufficient technical support for "Guoaokeji". The R & D team systematically optimized the supply links from the aspects of structure, materials, production, and assembly step by step. Finally, the products of "Guoaokeji" achieved breakthroughs in three key indicators: first, force control in high - speed state. Under the state of 8G acceleration and 1000 mm/s running speed, it can achieve a force control index of 30 grams of pressure ± 3 grams; second, the straightness of the output shaft is stable at ± 1μm; third, the radial runout of the output shaft is stable at ± 1μm.

In July 2021, the products of "Guoaokeji" entered the semiconductor packaging and testing line of leading customers. On this basis, "Guoaokeji" is extending to the front - end processes in semiconductors. This year, it will release a new product series for front - end semiconductor equipment and expand its customers from back - end equipment manufacturers to front - end equipment manufacturers.

II. Conduct application - oriented R & D and expand the market in fields such as 3C and new energy

Based on the underlying technical solution, "Guoaokeji" began to conduct application - oriented R & D according to market demand, targeting the 3C field represented by the Apple supply chain, and using multi - degree - of - freedom precision motors to replace the traditional solution of servo motors plus lead screws. In Li Siyang's description, from semiconductors to 3C is a "down - dimensional" product planning: "This type of product takes cost into consideration and will reduce some requirements for accuracy and technical indicators because this industry really doesn't need such high indicators."

However, the relaxation of technical requirements also means a lower competition threshold. The commercial competition in the 3C field is more intense. Besides price, the consistency and stability of products need to be compared. According to Li Siyang, the assembly process of motor parts is complex, and it is also crucial to confirm the accuracy of each machined part. The know - how accumulated by "Guoaokeji" in numerous product tests and actual iterations has become a competitive barrier, enabling cost reduction while maintaining high quality.

Li Siyang expects that the demand in the 3C field is large. With the stable mass production of relevant products, the future shipment volume will increase geometrically. To meet the production capacity demand, "Guoaokeji" established its first self - owned machining factory and assembly factory in Ganzhou in 2024 to better control the quality of mass production and delivery and project costs.

In addition, "Guoaokeji" is promoting product R & D in fields such as new energy vehicles, robots, and medical care. In the field of new energy vehicles, it is cooperating with new car - making forces to develop new technologies to meet the needs of integrated body die - casting and lightweighting of new energy vehicles and achieve domestic substitution. The products are expected to be launched this year. In the field of robots, it is developing a complete set of linear - rotary two - axis module solutions from collaborative robots, humanoid robots to dexterous hands and will send samples to internal customers by the end of this year. In the medical field, product R & D will be gradually promoted according to market demand.

From 3C, new energy vehicles to robots, the application - oriented R & D idea of "Guoaokeji" is to be close to the market with rigid demand. "What we are more concerned about is whether this demand is really a rigid demand." Li Siyang further explained, "For example, new energy vehicle manufacturing is a very rigid demand. Imported solutions are already being used, but they are very expensive. If domestic products can be developed first and also have technological advantages, it will be much easier."

In terms of future planning, "Guoaokeji" has entered a critical period of capacity improvement. It is expected that its sales revenue in 2025 will increase by more than 100% year - on - year. The primary task is to expand production capacity to ensure product delivery. At the same time, it will achieve product breakthroughs in new business lines such as front - end semiconductor processes, new energy vehicles, and robots.
