Application Industry: Used in deep hole and blind hole electroplating process of high aspect ratio PCB, which is the first choice for 5G PCB boards.

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.

Liyuan PCB power supply has the comprehensive advantages of stable performance (sealing and structure), high efficiency (the highest efficiency can exceed 94%), high control precision, small size, all-new installation mode to reduce costs, improve electroplating uniformity, and optimize electroplating process.

Positive and negative pulse power supply can increase electroplating speed. Improve the uniformity of copper plating, deep hole plating uniformity; Reverse pulse electroplating can control the deposition rate of copper in the high current density area, so as to improve the thickness uniformity of surface copper and pore copper, and eliminate the “dog bone” phenomenon.

• Positive time T1: 5-2000ms Step: 100us
• Negative time T2: 0.5-60MS  step: 100us
• Ratio of positive pulse time to negative pulse time =20/1.
• The negative current is 4 times of the positive current (adjustable).
• The negative voltage is about 2-2.5 time of the positive voltage.
• The negative pulse device has shorter ascending and
• Descending time and is generally 150us
• The coaxial cable and twisted cable are optional
• Multi-phase combined wave form setting
• Improve deep plating capability and electroplating efficiency by 30% – 50%, shorten the electroplating time.
