Changzhou Weiden Electronic Equipment Co., Ltd.: Forty Years of Craftsmanship Forging the Benchmark in Surface Treatment Equipment
As a national-level high-tech enterprise, Changzhou Weiden Electronic Equipment Co., Ltd. has consistently focused on intelligent, eco-friendly surface treatment engineering equipment since its establishment in 1983, providing end-to-end solutions for high-end sectors including national defense, military, and new energy vehicles. With over 20 patented technologies, the company's intelligent control system for automated electroplating alloy production lines leads the domestic market. Its modular software design enables unified regulation across multi-plating production lines, boosting remote fault warning rates by 40%. In 2025, the company was again named one of Jiangsu Province's Top Ten Suppliers by the Surface Engineering Industry Association, having exported over 20 production lines to date. Its client roster includes leading institutions such as China Electronics Technology Group Corporation and Nanjing Hongguang Parachute Equipment Co., Ltd.

In the manufacturing of gold fingers for 5G communication equipment, traditional direct current electroplating often produces dendrites and porosity exceeding 15%, leading to wear failure after 500 insertion cycles. The Weiden Electronics technical team innovatively adopted a horizontal pulse electroplating process. By precisely controlling three core parameters, they achieved micron-level uniform gold plating:

In July 2024, the Ministry of Ecology and Environment jointly issued new regulations with the Ministry of Industry and Information Technology, significantly tightening wastewater discharge limits for the electronics industry. For PCB manufacturers, the total copper discharge concentration limit was reduced from the current 1.0 mg/L to 0.3 mg/L, while discharge limits for heavy metals nickel and tin were simultaneously cut by 40%. The new standards require existing enterprises to complete upgrades by 2025, projected to generate a ¥18.2 billion market for environmental equipment renewal.

Changzhou Weiden Electronic Equipment Co., Ltd. (hereinafter referred to as "Weiden Electronics") officially delivered a high-precision fully automated etching production line to an AVIC-affiliated research institute in June 2024. This production line will be applied to the manufacturing of turbine blades for next-generation fighter jet engines, addressing the bottleneck challenge of micro-hole processing in high-temperature alloys.
