A leading international semiconductor company required electronic-grade hydrofluoric acid. Shanghai Beiling, in collaboration with Nanjing University's laboratory, completed ppb-level purity optimization within three months, providing small-batch samples with SGS test reports. A ten-thousand-ton production line was simultaneously launched, ultimately achieving a metal ion contamination rate of less than 0.1 ppb for the 14nm production line, and reducing the delivery cycle to 28 days. The client awarded Beiling "Annual Best Supplier" certification.

An African rare earth mining company required 99.999% high-purity hydrofluoric acid for tungsten ore purification. Beiling, relying on its joint laboratory with the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences, developed gradient purification technology. Through its own factory's dual quality inspection system and Chinese customs inspection, dedicated ship transportation covered the mining area, and an on-site technical team optimized the etching process, increasing the rare metal recovery rate by 15% and saving over US$8 million annually.

A leading domestic panel manufacturer required a nanoscale glass etching solution. Beiling, in collaboration with Xiamen Jimei University's Jiageng Laboratory, developed a nitrogen trifluoride-tetrafluoromethane synergistic formula, achieving a line width control accuracy of ±10nm. The etching uniformity was certified at 98% by a third-party SGS certification. Combined with vibration-resistant packaging and consolidated sea freight services, the transportation damage rate was only 0.3%, helping the customer improve the yield of their 5G optical modules to 99.2%.
