HNLH Precision Grinding Technology Corporation is committed to R&D and manufacturing of micron, nanoscale diamonds, polishing films, abrasive fluids, and precision grinding wheels.
The products are mainly in the fields of precision grinding and polishing related to the most advanced high-end manufacturing industries such as microelectronic materials, 3C materials, semiconductor materials, and integrated circuit materials.
The company has successively launched a series of precision grinding and polishing materials such as 50 nanometer diamond polishing liquid, polycrystalline diamond, various diamond grinding liquids, polishing liquids, grinding pads, and precision grinding wheels.
Among them, polycrystalline diamond is the first in the industry, and the abrasive pad products are the first to replace imported products in the 3C industry.
HNLH has the only national-level precision grinding and polishing application laboratory in the industry, as well as international advanced application processing equipment.
The laboratory can provide customers with processing experiments of various hard and brittle materials such as silicon carbide, sapphire, gallium nitride, ceramics, glass, etc., and cooperate with customers to develop grinding and polishing process solutions to provide customers with overall products and technical solutions.
Development of ultra-precision grinding and polishing materials
In 2011, HNLH successfully opened the Chinese semiconductor application market – silicon carbide crystal processing, and the products were recognized by customers and replaced imports, which became a milestone turning point for HNLH.
HNLH aims at the polishing and grinding of sapphire window wafers and sapphire substrate wafers, and based on the research and development foundation of silicon carbide crystal materials, cooperates with customers to develop grinding processes, develop a series of innovative products, and quickly occupy a large market share in China's sapphire crystal market .
"At that time, he led the team to enter the supply chain of world-renowned sapphire crystal manufacturers and several mobile phone foundry giants, and became its main supplier."
Hard disk giant Western Digital has demanded 100nm diamond polishing products from HNLH
The hard disk has very strict requirements on the polishing accuracy of the surface, and puts forward high requirements for the particle size and purity of the polishing material.
HNLH has realized the development of 100nm size diamond polishing products in a relatively short period of time, and the products have successfully provided services for Western Digital.
Up to now, the industrialization of 30nm diamond powder is still the core technology of HNLH
With micro-nano diamond as the core product, innovative products for different applications have been developed, such as polycrystalline diamond and various diamond grinding fluids.
In order to meet the needs of customers in terms of products and technologies, the company has successively developed grinding pads and series of polishing liquids. At present, it has the ability to provide high-quality product supply and technical services in a complete set of precision grinding and polishing processes in the high-end microelectronics and semiconductor industries.
