Abstract: A printed circuit board that can be connected with a pin connector and a method of manufacturing the printed circuit board are provided. Solidified solder can be formed on the tap unit without the need for additional processes, by applying solder printing to the tap unit at the same time it is applied to pads of the printed circuit board and, for example, by performing high temperature reflow. In addition, reliability and reduction in cost of a pin connector can be ensured without using a pin connector into which a high-priced wired solder is inserted. Rather a general pin connector can be used because the pin connector and the tap unit are connected to each other through the solidified solder formed on the tap unit.
