摘要： Disclosed herein is a printed circuit board including an outmost fine circuit pattern. In the board, an end of a via, which has the minimum diameter, is connected to the outmost circuit layer of a substrate. The end surface, having the minimum diameter, is positioned at the outmost layer, so that the outmost circuit layer of the substrate, which needs to have a relatively high density in order to mount chips, compared to other circuit layers, can be more finely formed.

摘要： The printed circuit board includes the via formed with the electroplating layer unlike a conventional via formed with an electroless plating layer and an electroplating layer and having a cylindrical shape, and thus exhibits good interlayer electrical connection and high reliability of physical contact upon thermal stress caused by the variance in physical properties of material depending on changes in temperature. The via has no upper land, and thus a fine circuit pattern of the circuit layer can be formed on the via.

摘要： This invention relates to a printed circuit board having a landless via hole, including a circuit pattern formed on a via made of a first metal and having a line width smaller than the diameter of the via hole, in which the circuit pattern includes a seed layer made of a second metal and a plating layer made of a third metal, which is different from the second metal, and to a method of manufacturing the same. In the printed circuit board, the via has no upper land, thus making it possible to finely form the circuit pattern which is connected to the via, thereby realizing a high-density circuit pattern.

摘要： Disclosed are a carrier substrate including an insulating base material with a copper foil layer formed on at least one surface thereof, a metal layer formed on the copper layer and having a length shorter than that of the copper foil layer, and an insulating layer formed on the metal layer, a fabrication method thereof, a printed circuit board (PCB) using the same, and a fabrication method thereof. Because there is no land at the via and core in the substrate, because a circuit pattern connected with the via can be formed to be finer, so the circuit pattern can be highly integrated and the substrate can become thinner. Thus, a printed circuit board (PCB) having a smaller size and reduced number of layers can be fabricated.

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.
