  • Publication number: 20110186342
    Abstract: A single layered printed circuit board and a method of manufacturing the same are disclosed. In accordance with an embodiment of the present invention, the method can include forming a bonding pad, a circuit pattern and a post on a surface of an insulation film, in which one end part of the post is electrically connected to at least a portion of the circuit pattern, pressing an insulator on the surface of the insulation film, in which the circuit pattern and the post are buried in the insulator, selectively etching the insulator such that the other end part of the post is exposed, and opening a portion of the insulation film such that at least a portion of the bonding pad is exposed.

  • Publication number: 20110110058
    Abstract: A single-layer board on chip package substrate and a manufacturing method thereof are disclosed. In accordance with an embodiment of the present invention, the single-layer board on chip package substrate includes an insulator, a circuit pattern and a flip-chip bonding pad, which are formed on an upper surface of the insulator, a conductive bump, which is in contact with a lower surface of the circuit pattern and penetrates through the insulator, a solder resist layer, which is formed on the upper surface of the insulator such that at least a portion of the flip-chip bonding pad is exposed, and a flip-chip bonding bump, which is formed on an upper surface of the flip-chip bonding pad in order to make a flip-chip connection with an electronic component.

  • Publication number: 20110100952
    Abstract: 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.

  • Publication number: 20110095425
    Abstract: 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.
