CSOT is a leading enterprise in China’s display panel industry, continuously making breakthroughs in the R&D and mass production of high-end LCDs, flexible OLEDs, and cutting-edge display technologies. Behind these achievements lies reliable industrial chain collaboration. As its long-term supplier of ultra-clean wipes, Baoshili has built a solid defense for the clean environment of Huaxing Optoelectronics’ advanced production lines with independently innovated clean products such as microfiber and polyester fiber wipes.

01. Introduction to CSOT

Founded in 2009, CSOT is a national high-tech enterprise under TCL Group, specializing in the semiconductor display field and a leading display manufacturer in China. Headquartered in Shenzhen, it operates multiple panel production lines and module bases in Shenzhen, Wuhan, Huizhou, Suzhou, Guangzhou, and India, forming a global industrial chain covering large, medium, and small-sized panels as well as high-end display applications.

As one of the world's leading display panel enterprises, Huaxing Optoelectronics has made remarkable achievements in technological independence and high-end development in recent years. In LCD panel manufacturing, micron-level dust can cause defects such as bright spots and dark patches on screens, so Huaxing Optoelectronics has extremely strict standards for clean consumables. As its LCD panel production technology continues to upgrade, requirements for indicators such as fiber residues, chemical compatibility, and electrostatic control have also increased. Through continuous investment in technological R&D and professional services, Baoshili has made continuous breakthroughs in performance improvement and size customization, providing high-performance cleaning consumables for Huaxing Optoelectronics' production lines.

• Material and Structure: 100% polyester fiber or microfiber, manufactured using continuous weaving technology for durability.

• Excellent Adsorption: Strictly controls dust, ions, and other contaminants during production to ensure no secondary pollution to the environment during wiping; superior water absorption for effective cleaning of splatters and stains.

• Softness: Gentle cleaning due to soft properties, avoiding damage to equipment surfaces.

• Edge Sealing Technology: Hot cutting, laser, and ultrasonic edge sealing to prevent fiber shedding from edges.

• Diverse Product Types: Successfully developed a series of products including Polyester / Microfiber / ESD Cleanroom Wipes / Cleanroom Roll Wiper / Raw Fabric, meeting differentiated needs on the production line.

Founded in 1999, Baoshili has grown into a benchmark enterprise in China's high-end cleanroom wipe industry. With a 30,000-square-meter self-built factory in Xiamen, the company realizes full-chain independent manufacturing from fiber weaving, cloth processing to clean packaging, establishing an integrated R&D, production, and sales closed loop, effectively ensuring the stability of product quality.

With profound technical accumulation, Baoshili owns nearly 50 independent intellectual property rights, making continuous breakthroughs in the optimization of microfiber chemical components and innovation in weaving processes, creating ultra-clean wipes with leading performance. Its products serve fields such as LCD panels, semiconductors, and medical care, with clients including global leading enterprises such as Samsung, BOE, and CSOT.

Recently, Baoshili‘s semiconductor-grade ultra-clean PFA fitting “1/2” butt-weld tee” successfully passed performance tests including roughness and metal ion leaching, meeting SEMI F57 specifications. As a key model in the company’s semiconductor-grade PFA fitting product lineup, it not only marks Baoshili’s breakthrough in the field of high-purity fluid core components but also supports the company in building an integrated solution for semiconductor-grade chemical delivery systems.

With an inner surface roughness of Ra ≤ 0.35μm, it prevents fluid retention and scaling, reducing contamination risks.

The ultra-clean PFA fitting forms a molecular-level bond with ultra-clean PFA pipes through hot-melt welding, creating a complete chemical delivery system and ensuring the purity and stability of semiconductor manufacturing processes.
