Shenzhen Rosin Tec New Materials Co., Ltd.

Shenzhen Rosin Tec New Materials Co., Ltd. (referred to as "Xinzhihe") was established in 2006 and is located in Tianhao Industrial Park, Shiyan Street, Bao'an District, Shenzhen. As a specialized supplier in China, the company focuses on electronic soldering chemicals, solder paste, and flux raw materials. With nearly two decades of deep engagement in the upstream SMT electronic soldering industry chain, Xinzhihe has established a comprehensive service pipeline covering raw material selection, formula adaptation, and mass production process debugging. It provides domestic solder material manufacturers with integrated electronic soldering new material solutions featuring stable performance, reliable quality, and high cost-effectiveness.

Leveraging years of industry technology expertise, the company has established six standardized core product matrices: electronic-grade colophony and hydrogenated modified rosin series, high-purity multivariate organic acids and acid anhydride activators series, SMT-specific coupling-type high-boiling solvents, solder paste-specific antioxidants, reversible organic thixotropic agents, and lubricating corrosion-inhibiting additives. All products undergo targeted purification and screening for precision PCB reflow soldering applications, strictly controlling three key impurity indicators—metal ions, ash content, and high-temperature volatile residues. The entire product portfolio complies with RoHS 2.0, REACH, and halogen-free exemption standards, serving a wide range of high-end manufacturing sectors including automotive electronics, 5G communications, precision consumer electronics, and industrial control PCBs. 

The company focuses on the diversified niche segment of electronic soft soldering new materials, sourcing all raw materials directly from top-tier domestic and international chemical manufacturers. It has also established a dedicated incoming material quality inspection system tailored to the SMT soldering materials industry, ensuring control over the insulation reliability of raw materials, post-soldering wetting and ductility, and long-term stability at room temperature. Leveraging mature direct supply channels from manufacturers, a spot warehousing base in the Pearl River Delta, and an efficient logistics distribution system, the company can meet customers' large-volume, uninterrupted, and cross-regional stable supply demands. 

Since its inception, Xin Zhihe has consistently adhered to the business philosophy of "prioritizing stable quality and achieving technical collaboration for mutual benefit," deeply engaging in the upstream fine chemical supply chain for SMT. Moving forward, it will continue to refine its raw material quality control system and upgrade supporting technical services, striving to become a strategic partner for high-purity, high-compatibility, and low-cost soldering materials that garners long-term trust from national solder paste and flux manufacturers.
