HNLH Precision Technology Group focuses on R&D and the production of micron and nanometer diamonds, polishing films, grinding fluids, and precision grinding wheels. In the field of precision grinding, it has been constantly innovating…
In order to meet the needs of the most advanced high-end manufacturing related precision grinding and polishing processing fields such as microelectronic materials, 3C materials, semiconductor materials, and integrated circuit materials.
In 2006, HNLH successfully entered the high-end markets in developed countries such as the United States, Japan, and Europe.
In terms of product technology innovation, the company has successively introduced a series of precision grinding and polishing materials such as 50 nanometer diamond polishing fluid, polycrystalline diamond, various diamond polishing fluids, polishing fluids, polishing pads, and precision grinding wheels. “Polycrystalline diamond-like diamonds are the industry’s first , Abrasive pad products are the first to replace imported products in the 3C industry."
In terms of application research, HNLH has the only national precision grinding and polishing application laboratory in the Chinese industry, as well as international advanced application processing equipment. The laboratory can provide customers with various hard and brittle materials such as silicon carbide, sapphire, gallium nitride, ceramics, glass and other processing experiments, and cooperate with customers to develop grinding and polishing process solutions to provide customers with overall products and technical solutions.

Develop ultra-precision grinding and polishing products
In 2010, China's semiconductors began to develop gradually, but equipment, materials, and consumables all depended on imports. The application of diamond to the grinding and polishing of semiconductors is a good opportunity. After investigation, the differentiated development strategy is determined within the company, bypassing the traditional machining, stone processing and other industries. HNLH focuses on precision grinding and polishing materials, and the market is positioned in the field of microelectronics and semiconductor material processing.
In 2011, the company successfully opened the Chinese semiconductor application market-silicon carbide crystal processing. The products were recognized by customers and replaced imports, which became a milestone turning point for the company.
Later, products expanded to the 3C electronics market, and China's market share continued to increase, surpassing the United States to become the world's largest consumer electronics market.
HNLH aims at the polishing and grinding market of sapphire window wafers and sapphire substrate wafers, and based on the research and development basis of silicon carbide crystal materials, cooperates with customers to develop grinding processes and develops a series of innovative products, which quickly occupy a larger market in the Chinese sapphire crystal market Share. "At that time, he led the team into the supply chain of the world-renowned sapphire crystal manufacturer and several major mobile phone foundry giants and became its main supplier."
In 2004, China began to use the detonation method to produce nanometer diamonds, which became a hot spot for industry investment at that time, and many manufacturers invested in projects for this purpose. But after the diamond was produced by blasting, everyone looked at each other and didn't know how to use it.
HNLH benefits from the advantages of the international market. Among its previous customers, Western Digital, the hard disk giant, expressed the company's demand for 100nm diamond polishing products.
However, hard drives have very strict requirements on the polishing accuracy of the surface, and high requirements on the particle size and purity of the polishing materials are put forward. The diamond produced by the detonation method is a mass of black mud. How to control its accuracy to 100nm is a big test for the R&D team.
In order to solve this problem, the company's R&D team worked with experts from the Grinding Institute of the Chinese Academy of Sciences and Western Digital to conduct technical research and testing. Finally, the 100nm size was realized in a short period of time, and the product successfully passed the acceptance of Western Digital. "As of now, realizing the industrialization of 30nm diamond is still HNLH's core technology."
Over the years, HNLH has pursued development driven by its differentiated development strategy. With micron nanodiamond as its core product, HNLH has innovated and developed innovative products for different applications, such as polycrystalline diamond-like diamonds and various types of diamond slurry. In order to meet the needs of customers in terms of products and technology, United Precision has successively developed polishing pads and series of polishing fluids. At present, it has the ability to provide high-quality product supply and technical services in the high-end microelectronics and semiconductor industries. .
In 2020, HNLH applied for the international standard for nanodiamonds. If the international standard is approved, it will not only play a positive role in the superhard industry, but also expect a wide range of functional materials in the fields of biomedicine, surface treatment, composite applications, etc. Application promotion.
