High Frequency Pulse Power Supply GMF/GMS Series for Surface Treatment - China Suppliers & Factory
Product Feature
GM series have pulse waveform output function, compared with high frequency switching power supply, it can obtain higher density deposit layer in electroplating process.
In the electroplating system where additives are not allowed or a small amount of additives are allowed, a fine, flat and smooth coating can be obtained by high-frequency pulse power supply electroplating.
Fully digital control system equipped with high-precision sensors to ensure the accuracy of current and power.
Advanced digital intelligent management system can monitor the power output in real time.
Application Scope: GM series of power supplies can be widely used in hardware electroplating, automobile plate, bathroom treatment, industrial equipment, aluminum foil, consumer electronics and other industries.
Technical Principle
With the increasing complexity, thickness and path density of PCB board, as well as the decreasing aperture and path width, the traditional DC electroplating becomes more and more unsatisfactory, and it is difficult for DC electroplating technology to provide high-speed electroplating and even electroplating distribution for these products. This is mainly concentrated in the central part of the hole, that is, in the field of low current density, which leads to more copper distribution in the edge part of the hole than in the central part of the hole. The positive and negative pulse power supply regulates the aggregation and distribution of copper ions in high and low current densities through the action of pulses.

Frequently Asked Questions
What are the primary benefits of the GM series' pulse waveform output?
Compared to traditional high-frequency switching power supplies, the GM series' pulse waveform output allows for a higher density deposit layer during the electroplating process.
Can I get a smooth coating without using additives?
Yes. In electroplating systems where additives are restricted or allowed only in small amounts, the high-frequency pulse power supply enables you to obtain a fine, flat, and smooth coating.
Why is pulse power supply better than traditional DC electroplating for complex PCBs?
Traditional DC electroplating struggles with high-density, complex PCBs, leading to uneven copper distribution (more on the edges than the center of the holes). The positive and negative pulse power supply resolves this by regulating the aggregation and distribution of copper ions in both high and low current densities.
What is the output precision and control capability of the GM series?
The GM series features a fully digital control system equipped with high-precision sensors that ensure an output precision of ±1%, along with real-time monitoring of the power output.
What stable voltage waveforms does this power supply support?
It supports multiple stable voltage waveforms including DC, multi-section curve control, single pulse, DC superposition pulse, double pulse, and positive/negative pulse clusters.
Which industries can use the GM series power supplies?
They are widely applicable in hardware electroplating, automobile plates, bathroom treatment, industrial equipment, aluminum foil, consumer electronics, and related manufacturing industries.
