Production Introduction
Due to the design requirements of printed circuit boards (PCBs) leaning towards fine line diameter, high density, small hole diameter (high aspect ratio, even microvias), and blind hole filling, traditional direct current electroplating has become increasingly inadequate, especially in the plating of the hole center in through-hole plating, where an issue commonly arises with excessive copper layers at both ends of the hole but insufficient copper layer in the center. This uneven plating affects the effectiveness of current transmission, directly leading to poor product quality. To address these issues, the use of horizontal reverse pulse copper plating technology is required.

Features & Applications
Horizontal reverse pulse copper plating employs low tank voltage, low energy consumption technology, equipped with titanium anodes that have good corrosion resistance and a low rate of loss. The structure is lightweight and stable in size, providing excellent operational convenience, reliable plating performance, long life, and cost savings. It can be used for PCBs, CCLs, and is widely used in emerging industries such as home appliances, communications, and the 3C industry.
