  • Printed wiring board, and manufacture thereof
    Patent number: 6252176
    Abstract: A printed wiring board includes an insulating layer, conductive layers respectively formed into predetermined circuit patterns on the upper and lower surfaces of at least the insulating layer, and a conducting section formed in a portion of the insulating layer so as to enable electrical connection between the upper and lower conductive layers. A thickness of the insulating layer is varied to change the electric characteristics of the printed wiring board according to a circuit configuration of the conductive layers.
    Type: Grant

  • Printed wiring board with two ground planes connected by resistor
    Patent number: 6143990
    Abstract: A printed wiring board is provided with a ground wiring structure corresponding to a signal wiring structure. The ground wiring structure is furnished with a first wiring layer located on a first side surface of an insulating layer along with the signal wiring layer, and a second wiring layer located on another side surface of the insulating layer and sandwiching the insulating layer against the signal wiring layer. A resistor is interposed between the first wiring layer and the second wiring layer.
