20110079421 | PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - Disclosed herein is a printed circuit board, including: a base substrate; insulation layers which are formed on both sides of the base substrate and in which trenches are formed; and circuit layers including circuit patterns and vias formed in the trenches using a plating process. The printed circuit board is advantageous in that trenches are formed in both sides of a base substrate, so that a fine circuit pattern can be simultaneously formed on both sides thereof, thereby simplifying the manufacturing process thereof. | 04-07-2011 |

20110089138 | METHOD OF MANUFACTURING PRINTED CIRCUIT BOARD - Disclosed is a method of manufacturing a printed circuit board, including (A) forming a first circuit layer on a base substrate and forming a first insulating layer thereon, (B) forming trenches including dummy trenches and wiring trenches on the first insulating layer and plating the trenches, thus providing a trench circuit layer including a dummy circuit pattern and a wiring circuit pattern, (C) removing the dummy circuit pattern of the trench circuit layer, and (D) forming a second insulating layer on the trench circuit layer from which the dummy circuit pattern was removed. The method reduces deviation of plating thickness and thus realizes the design density of a trench circuit layer. | 04-21-2011 |
