Pulse Plating Rectifier
The pulse plating rectifier is an advanced surface finishing power solution developed based on cutting-edge high-frequency switching power supply technology. This periodic reverse pulse power supply features an integrated SDD (DC) commutation function, offering a versatile range of waveform outputs including forward/reverse pulse, pure DC, sine-wave, and single pulse. This high-precision waveform generator is engineered to meet critical industrial needs such as electrolytic coloring, eliminating the hydrogen embrittlement effect, and dramatically refining grain structure.
Advanced Technical Applications
This dual-pulse electroplating modulator is specifically optimized for high-end metallization processes across several highly demanding industries:
- Precious Metal Deposition: High-uniformity plating of gold, silver, nickel, and tin.
- Semiconductor & Electronics: Surface treatment of semiconductor lead frames, high-density connectors, contact pins, and micrometer-scale precision circuit patterns.
- Advanced PCB Manufacturing: Copper deposition for rigid multi-layer boards, microwave circuit boards, high-aspect-ratio plated through-holes (PTH), microvias, and deep-blind vias.
- Specialized Applications: Industrial iron plating and advanced scientific electrochemical research.
