High Frequency Pulse Power Supply GMF/GMS Series from China Suppliers - Ideal for Electroplating and Surface Treatment 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.
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 applications for the GM series power supplies?
The GM series of power supplies is highly versatile and widely used in hardware electroplating, automobile plate fabrication, bathroom fixture treatment, industrial equipment, aluminum foil production, and consumer electronics manufacturing.
How does the GM series achieve high-density deposit layers?
Unlike standard high-frequency switching power supplies, the GM series features a specialized pulse waveform output function. This allows the system to achieve a significantly higher density deposit layer during the electroplating process.
Can I obtain a smooth coating using the GM series without using additives?
Yes. In electroplating systems where additives are strictly restricted or allowed only in minimal amounts, the high-frequency pulse output of the GM series enables you to obtain a fine, flat, and exceptionally smooth coating.
What makes the GM series control system reliable?
The GM series is equipped with a fully digital control system integrated with high-precision sensors. This guarantees the absolute accuracy of output current and power, backed by an advanced digital intelligent management system that monitors output in real-time.
How does positive and negative pulse technology improve PCB electroplating?
Traditional DC electroplating often results in uneven copper distribution, with more copper at the edges than in the center of PCB holes. Positive and negative pulse power supplies resolve this by dynamically regulating the aggregation and distribution of copper ions in both high and low current densities.
What types of stable voltage waveforms does the GM series support?
The GM series supports multiple waveforms including DC, multi-section curve control, single pulse, DC superposition pulse, double pulse, as well as positive and negative pulse clusters.
