Key exhibiting products and technological highlights
Photovoltaic industry application products
At this exhibition, Zhongdu Technology highlighted its self-developed comprehensive solution for photovoltaic copper electroplating technology, encompassing high-precision electroplating solutions and accompanying precision electroplating equipment. This technology, through innovative additive formulations and pulse electroplating processes, can notably enhance the photoelectric conversion efficiency of photovoltaic cells, reducing raw material costs by over 30% compared to traditional silver paste processes. The on-site demonstration of copper electroplated photovoltaic cell samples showcased metallization line widths below 20 microns and adhesion forces exceeding 5N, garnering significant attention from leading photovoltaic companies such as Tongwei and Longi. According to the company’s technical leader, this process has been implemented on the mass production lines of multiple domestic photovoltaic enterprises, producing over 1GW of high-efficiency photovoltaic cells.
PCB, semiconductor, electronic plating additives
In response to the high-end demands of the electronic information industry, Zhongdu Technology exhibited a series of high-precision electroplating solution products, including the MC-1200 pulse copper plating process applied to semiconductor packaging. The MC-1200 pulse copper plating process utilizes a unique additive system, enabling uniform copper plating on high aspect ratio circuit boards with a thickness deviation of the plating layer controlled within ±5%, significantly enhancing the speed and integration of chips.
Hardware electroplating additive
Focusing on high-end hardware fields such as automotive components, Zhongdu Technology showcased a series of additive products including acidic zinc-nickel alloy and alkaline zinc-nickel alloy. Among them, the acidic zinc-nickel alloy coating exhibits a salt spray resistance of over 1000 hours and a corrosion current density below 0.1μA/cm², significantly enhancing the corrosion resistance and service life of automotive components. This series of products has been certified by international Tier 1 suppliers such as Bosch and Brembo, and is widely used in surface treatment of key components such as automotive chassis and brake systems.
Highlights of technological innovation
At this exhibition, Zhongdu Technology highlighted three major technological innovation highlights: First, through industry-university-research cooperation with teams from Shanghai University and Xiamen University, a low-energy electroplating process was developed, which reduces energy consumption by more than 25% compared to traditional processes; second, an independently developed intelligent electroplating control system, which enables real-time monitoring and automatic adjustment of plating solution components, and improves the control accuracy of plating thickness to ±3%; third, all series of products comply with EU RoHS and REACH standards, among which environmentally friendly processes such as cyanide-free electroplating and low-chromium passivation have already met future environmental regulations in advance. These innovative technologies reflect the company’s leading position in the field of green and intelligent surface treatment.
Industry influence and cooperation exchange
Key customer communication
During the exhibition, Zhongdu Technology engaged in in-depth technical exchanges and business negotiations with multiple industry leaders. The company’s management team discussed with technical leaders from companies such as CATL and Huawei Devices on topics such as the latest application progress of photovoltaic copper electroplating technology and innovative directions for semiconductor packaging electroplating processes, and reached multiple cooperation intentions. In addition, the company established contacts with several overseas customers, laying the foundation for expanding into the international market.
