  • Printed wiring board
    Patent number: 10887989
    Abstract: A printed wiring board of the present invention includes an insulating substrate layer; a first conductive layer laminated to one surface of the substrate layer; a second conductive layer laminated to another surface of the substrate layer; and a via hole formed along an inner surface of a connection hole that is provided, in a thickness direction, through the substrate layer and the first conductive layer, the via hole electrically coupling the first conductive layer and the second conductive layer. A cross-sectional shape of the connection hole along at least one surface of the substrate layer is an irregular shape.
    Type: Grant
