摘要

A wiring board of an electronic device includes: a board terminal connected to a semiconductor device (semiconductor component); a wire formed in a first wiring layer and electrically connected to the board terminal; a conductor pattern formed in a second wiring layer and electrically connected to the wire via a via wire; and another conductor pattern formed in a third wiring layer and supplied with a first fixed potential. The conductor pattern and the another conductor pattern face each other with an insulating layer interposed therebetween, and an area of a region where the conductor pattern and the another conductor pattern face each other is larger than an area of the wire.

說明書

Also, the semiconductor device 70 and the connector 80 are mounted on the wiring board 10 and are electrically connected to each other. The wiring board 10 of the electronic device EDV7 has an upper surface (surface, main surface, front surface) 10t and a lower surface (surface, main surface, back surface) 10b located opposite to the upper surface 10t. Each of the semiconductor device 70 and the connector 80 is mounted on the upper surface 10t. The semiconductor device 70 and the connector 80 are electrically connected to each other via a wire 11 formed in the wiring layer WL1 (see FIG. 15). More specifically, the terminal 71D of the semiconductor device 70 and the terminal 81D of the connector 80, which constitute a supply path for a power-supply potential, are electrically connected to each other via a board terminal 17D, a wire 11D, and a board terminal 18D. Also, the terminal 71G of the semiconductor device 70 and the terminal 81G of the connector 80, which constitute a supply path for a ground potential, are electrically connected to each other via a board terminal 17G, a wire 11G, and a board terminal 18G.
