Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor device package having improved electrical and physical reliability. SOLUTION: A semiconductor device package comprises a first bump sequence comprising a plurality of first bumps arranged on an active surface of a semiconductor device to be separated from an outer edge of the semiconductor device by a first distance, a second bump sequence comprising a plurality of second bumps arranged on the active surface of the semiconductor device to be separated from an outer edge of the semiconductor device by a second distance longer than the first distance, and a third bump sequence comprising a plurality of third bumps arranged on the active surface of the semiconductor device to be separated from an outer edge of the semiconductor device by a third distance longer than the second distance. Between each adjacent first bump, there are sequences in which one of the second bumps and one of the third bumps are arranged alternately at least 2 times or more. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor memory module capable of arranging even long rectangular semiconductor memory chips in perpendicular direction and two trains. SOLUTION: Two adjacent horizontal trains of the module including a plurality of same type semiconductor chips 3 are formed between a center of printed circuit board 2 and each second edge 9. In the horizontal trains, the semiconductor memory chips 3 are perpendicularly arranged each other along y axis direction. In each adjacent horizontal train, the semiconductor memory chips 3 are packaged so that they may be adjacent each other along x axis direction. The semiconductor memory chips 3 in one side and the other side of adjacent horizontal trains are prepared in such a manner that different length sides are arranged in reciprocative manner, and have sides parallel to a contact strip 11 simultaneously. One side between two semiconductor memory chips 3 arranged at a location where they face each other in the y axis direction is parallel to the contact strip 11 in its short side, and the other side is parallel to the contact strip 11 in its long side.

Abstract:
PROBLEM TO BE SOLVED: To certainly solder each terminal land with outer-member terminals. SOLUTION: For FPC 40 in which a driver IC is mounted, a large number of lands 46a for driving signal arranged along the long arm of one side compose a land group by the side of ODD, meanwhile, a large number of lands 46b for driving signal arranged along the long arm of other side compose a land group by the side of EVEN. Both the land 46a and 46b for drive signal have a long rectangle-shape in the direction of X, and their lengths in the X-direction are equal (La=Lb), and the widths in the Y-direction is fixed irrespective of the positions in the X-direction. The width of the land 46a for drive signal in the Y-direction is larger than the one of the land 46b for drive signal in the Y-direction (Wa>Wb). Accordingly, the plane surface area of the land 46a for drive signal is larger than the one of the land 46b for drive signal. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To improve the mounting of an electronic apparatus in a card reader in a host and to minimize the electronic apparatus. SOLUTION: A removable electronic device has an application module for transferring data to or from a host having a plurality of contact terminals. The device comprises a first row of contact pads, each of the contact pads of the first row including a substantially tapered end, and a second row of contact pads, each of the contact pads of the second row including a substantially tapered end that corresponds to the substantially tapered end of at least one of the contact pads of the first row in an interweaving relationship, wherein the first and second rows of contacts pads are configured to receive the plurality of contact terminals.

Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive TCP and FPC capable of facilitating countermeasures to multiple pin arrangement and narrow pitch structure by a conventional facility, and to realize its manufacturing method. SOLUTION: An exclusive connecting terminal is arranged like a land-shaped stage or lattice for improving peel strength, and connecting land outline dimension width is set as a testable land size so that the dual use of a test terminal and the connecting terminal can be realized.
