  • Patent number: 8420945
    Abstract: A package substrate may include an insulating substrate, first circuit patterns, second circuit patterns and a test pattern. The first circuit patterns may be arranged on the insulating substrate. The second circuit patterns may be arranged on the insulating substrate. The second circuit patterns may be arranged between the first circuit patterns. The test pattern may be electrically connected between same polar terminals of the first circuit patterns and the second circuit patterns. Thus, electrical connections between the semiconductor chip and the circuit patterns may be tested before performing a process for cutting the package substrate.

  • Patent number: 7502231
    Abstract: Provided is a thin printed circuit board (PCB) for manufacturing a chip scale package (CSP). The thin printed circuit board includes a plurality of unit printed circuit boards, each of which is comprised of a circuit pattern, to which a semiconductor chip is adhered, and a substrate surrounding the circuit pattern. The unit printed boards are arranged in a row and includes a support molding, which is spaced a predetermined interval apart from the circuit pattern of each unit printed circuit board on the substrate of each unit printed circuit board and formed in a ring shape along the edge of the thin printed circuit board.

  • Patent number: 6653727
    Abstract: A semiconductor chip package with direction-flexible mountability comprising a switching circuit for switching a pin function according to the mounting direction of a package, a pair of pin-definition pins for defining the pin function and a pair of power supply leads, and a pair of ground leads. One of the power supply lead pair and the ground lead pair is rotation-symmetrical to the other, respectively. The semiconductor chip package with direction-flexible mountability in accordance with the present invention eliminates a process for indicating the mounting direction because the package can be mounted onto a substrate regardless the direction. Accordingly, the ID pin indication and a series of processes for testing the ID pin are eliminated and the malfunction due to the incorrect direction is prevented.
