Against the backdrop of the restructuring of the global electronics manufacturing industrial chain, Southeast Asia, with its geographical advantages and proactive industrial policies, is rapidly becoming a core region for the transfer and agglomeration of the Printed Circuit Board (PCB) industry. The large-scale development of the industry has raised higher requirements for the stable supply, high quality and localized services of key upstream chemical materials. As a national-level single champion enterprise in sodium persulfate manufacturing, Fujian Zhanhua Chemical Co., Ltd. takes its core product—sodium persulfate—as a pivot to deeply integrate into and help the PCB industrial clusters in Southeast Asia achieve high-quality development.
Ⅰ Sodium Persulfate: The Process Cornerstone in Precision PCB Manufacturing
In the complex PCB production process, sodium persulfate plays a critical role. With strong oxidizing properties, it serves as an ideal micro-etchant featuring controllable reaction, no residue and uniform etching, mainly used in two core processes:
Desmear and recess etching after drilling: to clean the hole wall and ensure the adhesion of the subsequent copper plating layer;
Surface conditioning before pattern transfer: to clean and roughen the copper surface and guarantee the adhesion of photoresist.
As the PCB industry in Southeast Asia upgrades towards high-layer count and HDI (High-Density Interconnect) boards, requirements for the purity and stability of sodium persulfate have become increasingly stringent. As a key material ensuring circuit precision and reliability, its importance has become more prominent.
Ⅱ Professional Strength: Dual Guarantees of Large Scale and High Quality
Fujian Zhanhua Chemical has been deeply engaged in sodium persulfate for more than 20 years. With a solid market share and technological advantages, its core product sodium persulfate has been awarded the Single Champion Product in Manufacturing by the Ministry of Industry and Information Technology. The company also holds many national-level qualifications, such as national-level specialized, sophisticated, unique and new "Little Giant" enterprise, national-level high-tech enterprise and national-level green factory. Behind these honors lies the company’s strict control over the whole industrial chain: from raw material traceability to continuous optimization of production processes and precise testing of finished products, ensuring that key indicators such as active content and heavy metal residue are superior to market standards.
At present, Fujian Zhanhua Chemical has a large-scale supply capacity of 50,000 tons of sodium persulfate, 75,000 tons of ammonium persulfate and 12,000 tons of potassium persulfate annually, with its production capacity and comprehensive strength ranking among the top in the global persulfate industry. With the steady progress and upcoming commissioning of the company’s Phase III project, its overall supply capacity will be further enhanced, which can fully meet the growing raw material demand of high-end manufacturing industries such as global electronic information and PCBs. Relying on a stable production system and strict whole-process quality control, the company ensures high batch consistency and reliable product quality, providing long-term, safe and continuous raw material guarantees for overseas customers.
Ⅲ Deepening Localized Services: Building a Rapidly Responsive Supply Chain in Southeast Asia
Facing Southeast Asia as a core strategic market, Fujian Zhanhua Chemical has always focused on the supply of high-quality sodium persulfate and helped the steady development of the local PCB industry relying on a mature cooperation system. In the regional market layout, the company fully leverages the resource advantages of local professional trade partners, realizing the wide circulation of goods in various Southeast Asian countries through stable product supply, accurately meeting terminal production needs, and balancing market coverage and supply stability.
To better support regional cooperation, the company has continuously optimized its supply chain system and improved cross-border logistics and supply processes. Relying on the transit advantage of Xiamen Port, it shortens the cargo transportation cycle to ensure timely and stable delivery of products to all partners. Meanwhile, the company has established a professional technical and service team to provide comprehensive support for partners, including product quality assurance, technical consultation, sample support and after-sales inquiries, properly solving various problems encountered by customers in product application.
Through in-depth linkage with trade partners in various Southeast Asian countries, the company not only gives full play to its own advantages in production capacity and quality in the persulfate field, but also uses partners’ local channel resources to effectively break various barriers in cross-border market layout, achieve complementary advantages and mutual benefit, and lay a solid foundation for the continuous deepening and long-term expansion in the Southeast Asian market.
Ⅳ Collaborative Development: Boosting the Overall Improvement of Regional PCB Manufacturing Efficiency
The competitiveness of an industrial cluster lies not only in scale, but also in the collaborative efficiency of the supply chain and the overall manufacturing level. With the world’s leading production capacity and strict quality control, Fujian Zhanhua Chemical provides sodium persulfate products with extremely high batch stability for PCB enterprises in Southeast Asia, helping them reduce process adjustment costs caused by material fluctuations and improve the first-pass yield rate. This not only optimizes the production process of a single enterprise, but also promotes the steady improvement of the overall manufacturing level of the regional industry.
In the future, Fujian Zhanhua Chemical will continue to deeply explore the Southeast Asian market relying on its leading production capacity, technological advantages and mature service system. The company will further strengthen joint R&D with regional leading enterprises, explore the application potential of sodium persulfate in more precise etching processes, optimize product performance to meet the high-end demand of the industry. With more stable product supply and deeper industrial services, it will help PCB industrial clusters in Southeast Asia consolidate their development foundation, steadily move towards high-end development, and gradually enhance the global competitiveness of the regional industry.
