A method of manufacturing a printed circuit board having a bump is disclosed. The method includes preparing a first carrier having a first circuit formed thereon, compressing the first carrier to one surface of an insulation layer such that the first circuit is buried, stacking an etching resist on the first carrier in accordance with where the bump is to be formed and forming the bump by etching the first carrier. In accordance with an embodiment of the present invention, the difference in height between a bump and its adjacent bump in a printed circuit board can be reduced, and thus electrical connection between an electronic component and the printed circuit board can be better implemented.

Disclosed is a method of sequencing character information in order to increase precision of character recognition. The method includes: a pre-processing that extracts character information from an image to binarize the extracted character information through a predetermined threshold and extracts and thins a center line of the binarized character information; normalizing the pre-processed character information to character information according to a predetermined criteria; and sequencing the normalized character information using structural features including an end point or a divergence point of the character information. The present invention suggests an angle normalization method of input character information, a structural feature position determining method, and a structural feature numeral string generating method to strongly recognize characters configured by various fonts obtained from a natural scene regardless of an angle or a size of the characters.

Provided is a ball grid array substrate, a semiconductor chip package, and a method of manufacturing the same. The ball grid array substrate includes an insulating layer having a first surface providing a mounting region for a semiconductor chip, a second surface opposing the first surface, and an opening connecting the second surface with the mounting region of the semiconductor chip, and a circuit pattern buried in the second surface. Since the ball grid array substrate is manufactured by a method of stacking two insulating layers, existing devices can be used, and the ball grid array substrate can be manufactured as an ultra thin plate. In addition, since the circuit pattern is buried in the insulating layer, a high-density circuit pattern can be formed.
