摘要： There are provided a printed circuit board and a manufacturing method thereof. The manufacturing method of a printed circuit board includes: preparing a substrate having active regions and non-active regions, the non-active regions being formed on edges thereof; printing resists on dummy portions corresponding to the non-active regions of the substrate by using an inkjet printing method; curing the resists; and performing plating on the active regions of the substrate. The resists are masked on the dummy portions corresponding to the non-active regions of the substrate to prevent plating from being performed on the dummy portions, thereby reducing manufacturing costs.
