Abstract
An electronic apparatus includes a wiring board. The wiring board also includes a first wiring pattern that is provided on the wiring board and includes a first wiring portion extending in a first direction. The wiring board further includes a second wiring pattern that includes a second wiring portion extending in the first direction. The wiring also includes a first via provided on the first wiring portion, and a second via provided on the second wiring portion. A power supply circuit applies a first voltage to the first wiring portion at periodic time intervals. A detection circuit outputs an alert signal when a current flows through the second wiring pattern.
Claims16
An electronic apparatus, comprising:
- a wiring board;
- a first wiring pattern on the wiring board and including a first wiring portion extending in a first direction;
- a second wiring pattern on the wiring board and including a second wiring portion adjacent to the first wiring portion in a second direction intersecting with the first direction, the second wiring portion extending in the first direction;
- a first via on the first wiring portion;
- a second via on the second wiring portion;
- a power supply circuit configured to apply a first voltage to the first wiring portion at time intervals;
- a detection circuit that is electrically connected to the second wiring pattern and configured to output an alert signal when a current is detected flowing through the second wiring pattern when the first voltage is being applied to the first wiring portion;
- and
- a protective layer formed of a resin material, wherein
- the first wiring pattern and the second wiring pattern are not covered by the protective layer,
- the first wiring pattern further includes a third wiring portion that extends in the second direction and a fourth wiring portion that is separated from the first wiring portion in the second direction, a third via being on the fourth wiring portion,
- the second wiring pattern further includes a fifth wiring portion that extends in the second direction and a sixth wiring portion that is separated from the second wiring portion in the second direction, a fourth via being on the sixth wiring portion,
- the first wiring portion and the fourth wiring portion each have one end connected to the third wiring portion,
- the first wiring portion and the fourth wiring portion each extend toward the fifth wiring portion in the first direction,
- the second wiring portion and the sixth wiring portion each have one end connected to the fifth wiring portion, and
- the second wiring portion and the sixth wiring portion each extend toward the third wiring portion in the first direction.
