The 2026 Hanoi International Electronics and Smart Manufacturing Exhibition is a brand-new high-end event for Vietnam’s electronic manufacturing industry launched for the first time in 2026, held grandly in Hanoi from July 1 to 4. As essential chemical raw materials for electronic circuit manufacturing, persulfates are widely used in critical processes of printed circuit board (PCB) production, mainly for core procedures including copper surface roughening and microetching (copper surface roughening and cleaning). The overall quality of raw materials directly determines the patterning precision and finished product yield of circuit boards.
Having been deeply engaged in the electronic chemical supporting track across Southeast Asia for many years, Fujian Zhanhua Chemical attends the inaugural Hanoi international electronics exhibition this time to further deepen its market layout in Vietnam and the ASEAN region. By participating in this newly launched professional exhibition in Hanoi, the company focuses on brand promotion, customer development, client visits and expanding industrial influence within ASEAN, further consolidating its brand penetration and supply advantages in the PCB raw material market of Southeast Asia.
During the exhibition, Zhanhua Chemical centers on technological empowerment and targeted business docking. It comprehensively presents the process strengths, rigorous quality control standards and mature practical application schemes of its full range of persulfate products to local Vietnamese PCB manufacturers, circuit board producers and electronic process supporting suppliers, so as to efficiently realize precise matching between supply and demand as well as technical exchange and cooperation.
Ⅰ Core Application Positioning of Persulfates in PCB Manufacturing Processes
Precision PCB manufacturing is highly dependent on a stable and controllable wet process system, among which the microetching process puts forward the strictest requirements for consistency in chemical performance. Through uniform and controllable oxidative etching, persulfates form an evenly micro-roughened structure on the surface of copper foil, effectively enhancing the adhesion between dry film, solder mask ink and copper surface, and ensuring high precision of subsequent pattern transfer.
Etching uniformity and activity stability directly affect production yield: uneven etching easily leads to inconsistent adhesion, circuit notches, residual copper and process fluctuations. For this reason, modern PCB factories set extremely high access requirements for persulfates in terms of impurity control, batch consistency and reaction stability.
Supported by a full-process closed-loop quality control system, all persulfate products of Zhanhua Chemical strictly control sensitive impurities such as iron ions, heavy metals and moisture with stable and balanced active components. The products can precisely adapt to different production conditions of PCB manufacturing, effectively reduce etching fluctuations, improve surface uniformity, and help downstream customers boost product quality and production efficiency.
Ⅱ PCB Capacity Expansion and Raw Material Supply Demand in Southeast Asia
In recent years, the global electronic manufacturing industrial chain has kept transferring to Southeast Asia. In the process of undertaking industrial relocation, circuit board manufacturing, as a supporting link for finished electronic product assembly, sees accelerated capacity expansion in Vietnam’s electronics manufacturing sector. Demand for imported persulfates featuring high quality, high stability and sustainable long-term stable delivery keeps rising continuously.
At present, Vietnam’s local supporting system for high-end chemical raw materials is still under improvement, and most medium and large-sized PCB enterprises rely on compliant imported raw materials to guarantee production line quality. Having years of experience in developing export markets across Southeast Asia, Zhanhua Chemical possesses mature capabilities in dangerous goods export customs declaration and handling of compliant documents to fulfill orders in a standardized manner, providing Vietnamese customers with long-term, stable and quality-controllable bulk supply of persulfates.
Ⅲ Systematic Supporting Capacity of Zhanhua Chemical for the PCB Industry
Fujian Zhanhua Chemical’s product matching for the PCB industry is a systematic layout formulated according to the process characteristics and quality requirements of the industry.
In terms of products, its persulfate series covers three major varieties: ammonium persulfate, sodium persulfate and potassium persulfate, meeting the chemical material demands for microetching, cleaning, surface treatment and other procedures in PCB manufacturing. Diverse product specifications and packaging forms can adapt to feeding habits of PCB production lines of different scales.
In terms of quality, the company implements a standardized production and quality control system with full traceability from raw material incoming inspection to finished product outbound delivery. Targeting the limits on impurities such as iron ions and heavy metals specified by the PCB industry, special control is implemented on key indicators, and the batch stability of products has been continuously verified through large-scale industrial mass production.
Ⅳ Rooted in the Vietnamese Market, Further Deepening Development Across Southeast Asia
Participation in the 2026 Hanoi International Electronics and Smart Manufacturing Exhibition represents an important step for Zhanhua Chemical to deepen local brand layout in Vietnam. During the exhibition, the team held in-depth exchanges with multiple Vietnamese PCB manufacturers and electronic process suppliers, put forward targeted high-stability persulfate solutions, and gained an in-depth understanding of local capacity upgrading demands and process standards.
Going forward, oriented toward the development trend of Southeast Asia’s electronics industry, Zhanhua Chemical will continue to expand its brand influence in the Vietnamese market relying on three core advantages: stable product quality, mature export delivery capacity and professional technical support. It will provide long-term and reliable raw material guarantee for high-quality, standardized and refined production of the regional PCB industry, and drive the upgrading of the electronic manufacturing industrial chain in Southeast Asia.
