    摘要: Disclosed herein is a printed circuit board including a landless via and a method of manufacturing the printed circuit board. The printed circuit board includes a landless via having no upper land. The via includes a circuit pattern having a line width smaller than the minimum diameter of the via. The via does not have an upper land on an end surface thereof having the minimum diameter, and thus a circuit pattern connected to the via is finely formed, resulting in the high-density circuit pattern. Thus, a compact printed circuit board having a reduced number of layers is realized.
