Abstract
According to one embodiment, a printed circuit board includes a first conductive layer on an insulating layer, including connection pads, a first mounting pad, a second mounting pad, a second wiring connecting the first mounting pad and one of the connection pads, and a first reinforcing pattern extending from the second mounting pad, a second conductive layer on another surface of the insulating layer, including a third wiring connected to one of the connection pads, and a conductive via connecting the second mounting pad and the third wiring. The second conductive layer includes a pad portion on the third wiring, opposed to the second mounting pad, and a third reinforcing pattern extending from the pad portion and opposed to the first reinforcing pattern.
Claims11
A printed circuit board comprising:
- an insulating layer;
- a first conductive layer which is provided on one surface of the insulating layer and includes connection pads, a first mounting pad, a second mounting pad, and a second wiring connecting the first mounting pad and one of the connection pads;
- a second conductive layer which is provided on another surface of the insulating layer and includes a third wiring connected to one of the connection pads;
- and
- a conductive via which is provided penetrating the second conductive layer and the insulating layer and connects the second mounting pad and the third wiring, wherein
- the first conductive layer includes a first reinforcing pattern extending from the second mounting pad in a direction different from a direction of the third wiring, and
- the second conductive layer includes a pad portion provided on the third wiring and opposed to the second mounting pad with the insulating layer interposed therebetween, and a third reinforcing pattern extending from the pad portion and opposed to the first reinforcing pattern with the insulating layer interposed therebetween.
