Dual Water Cooled Synchronous Rectifier | Experts in High-Precision PCB Plating: Uniformity > 95%, Energy Efficiency Improved by 4%+

Tailored specifically for vertical continuous plating (VCP) in the PCB industry, the Dual Water-Cooled Synchronous Rectifier addresses the challenges of uneven current distribution and high energy consumption associated with traditional plating methods. Leveraging synchronous rectification technology and dual-output current balancing technology, it helps achieve the highest quality in both board-wide and pattern plating.


Experts in High-Precision PCB Plating

【Key Advantages: Precision Coating, Extreme Energy Efficiency, Smart Manufacturing】

1. Perfectly even: Dual-output technology completely eliminates differences between Side A and Side B

Designed specifically for VCP lines, it employs industry-leading dual-output current distribution technology. This technology reduces current errors—which typically exceed 10% in traditional electroplating due to cable impedance—to less than 1%, ensuring coating uniformity of over 95% and significantly improving the yield of finished PCBs.

2. Significant energy savings: Synchronous rectification technology can further improve DC conversion efficiency by 4%

By innovatively replacing traditional diodes with low-on-resistance MOSFET synchronous rectifiers, voltage drop losses are reduced to an extremely low 0.1V–0.2V. Overall DC/DC conversion efficiency is improved by more than 4%, saving you a significant amount on your annual electricity bills.

3. Superior Quality: Ultra-low ripple, with near-perfect control accuracy

Utilizing 85 kHz high-frequency switching technology, it delivers an extremely low output ripple coefficient. High-precision current control ensures excellent performance of the electrolyte during complex pattern plating, resulting in finer crystal structure and more precise thickness distribution of the plating layer.

4. Groove-mounted operation: Sealed with imported adhesive, resistant to acid and alkali corrosion

The entire unit features a fully sealed water-cooled design, with the core circuitry encapsulated in high-grade imported sealant, providing exceptional resistance to acid and alkali corrosion. The equipment can be placed directly next to the electroplating tank, reducing cable length and minimizing line losses.

5. Industry 4.0 Interfaces: Fully compatible with mainstream control protocols

All models come standard with RS485 digital control and support multiple communication protocols, including ProfiBus-DP, DeviceNet, and 4–20 mA. They integrate seamlessly into automated production lines, enabling precise real-time parameter monitoring and intelligent production scheduling.


【Technical Highlights】

  • VCP-Specific Design: Solves the problem of uneven current distribution in vertical continuous electroplating lines.
  • High-Frequency and High-Efficiency: Smaller size and lighter weight, maximizing space utilization.
  • Synchronous Rectifier (Dual Output): Eliminates differences in busbar/cable resistance through the coordination of the main and auxiliary units.
