Abstract: This work introduces the working principle, structural composition, technical characteristics and main innovative design points of the continuous copper coating production line on the surface of epoxy resin printed circuit board in detail. The main difficulties and solutions affecting the coating quality and production efficiency of epoxy resin printed circuit board are analyzed and pointed out. This work focuses on the scientific basis of increasing the deposition thickness of the coating and reducing the substrate temperature, and solves the problems of environmental pollution and water pollution caused by a large number of metal complexes produced by the traditional hole copper plating metallization process of printed circuit board. The self-developed anode ion source auxiliary system, RF bias technology, pulsed DC magnetron sputtering coating technology and auxiliary anode technology are comprehensively applied to improve the coating deposition rate. Under the condition of substrate transmission speed of 0.25m/min, the thickness of single-sided coating is not less than 3μm, and during the coating process, the substrate temperature shall not be higher than 80℃.

Key words: printed circuit board, anode ion source, RF bias, DC sputtering, auxiliary anode
