  • Patent number: 7285734
    Abstract: A circuit board includes a film substrate, a plurality of wiring layers arranged in order on the film substrate, and bumps formed on the wiring layers, respectively. Each of the bumps is provided across a longitudinal direction of a corresponding one of the wiring layers so as to extend over regions on both sides of the wiring layer above the insulating substrate, and a cross sectional shape of the bump taken in the width direction of the wiring layer is such that a central portion is higher than portions on both sides of the central portion. Accordingly, the bumps formed on the wiring layers can be held with strength sufficient for practical use against the force applied in the lateral direction.

  • Patent number: 7183491
    Abstract: To provide a printed wiring board where the impedance between pads through which differential signals pass has been set to a predetermined standard value. The printed wiring board includes a first conductor layer extending over an area excluding a hole formed for each pad group and filled with a dielectric, and a second conductor layer extending over an area containing areas facing the hole. The hole encompasses a plurality of areas facing predetermined respective pads which are adjacent to each other and which form the pad group from among the plurality of pads.
