PCB electroplating power supply mainly includes high-frequency switching power supply, single pulse power supply, high-speed positive and negative pulse power supply, mainly pulse power supply and high-precision DC power supply. The market share of PCB electroplating power supply reaches 75%. Over the years, WE have maintained good communication with high-end equipment manufacturers, brand potion manufacturers and end users. Many new technologies have been developed to improve the process quality and efficiency of PCB manufacturing from the aspects of power supply and equipment

The AC input voltage is transformed by a transformer to obtain low-voltage AC, rectified into DC by a rectifier bridge, and finally chopped by a MOS tube to obtain the required output pulse waveform. The control circuit samples the output current waveform and generates a pulse width modulation (PWM) signal to control the inverter circuit after closed-loop feedback to keep the output current waveform stable.
