    摘要: Disclosed is a printed circuit board including bumps formed using a conductive paste including carbon nanotubes and a photosensitive binder. A method of manufacturing the printed circuit board is also provided. The printed circuit board includes bumps formed using the conductive paste having carbon nanotubes, and can realize good electrical connection with electronic parts mounted thereon. The bumps can be formed at a fine pitch, thus realizing a circuit layer having a high density.

    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.

    摘要: Disclosed herein is a multilayered circuit board, including: a metal base layer including a metal layer formed through-holes, an insulating film formed on a surface of the metal layer, a first circuit layer having circuit patterns formed on one side of the metal layer and a second circuit layer having protruding connecting pads, formed on the other side of the metal layer; a build-up layer formed on the first circuit layer; and a solder resist layer. The multilayered printed circuit board is advantageous in that the thickness thereof is decreased and the bending strength and radiation characteristics thereof are improved.
