Abstract
Provided is an example of a technology capable of accurately controlling impedance. Provided is a substrate including a first through hole that penetrates a substrate from a first face to a second face of the substrate, and is electrically connected to a transmission line through which a signal is transmitted, a second through hole that is provided adjacent to the first through hole in plan view of the substrate, penetrates the substrate from the first face to the second face, and is electrically connected to a ground, and an adjustment unit that adjusts a distance between the first through hole and the second through hole in plan view of the substrate to adjust an impedance of a connection end of the first through hole with the transmission line.

A substrate comprising:
- a first through hole that penetrates the substrate from a first face to a second face of the substrate, and is electrically connected to a transmission line through which a signal is transmitted;
- a second through hole that is provided adjacent to the first through hole in a plan view of the substrate, penetrates the substrate from the first face to the second face, and is electrically connected to a ground;
- and
- an adjustment unit that adjusts a distance between the first through hole and the second through hole in the plan view of the substrate to adjust an impedance of a connection end of the first through hole with the transmission line,
- wherein a shape of a cross section of the first through hole differs from a shape of a cross section of the second through hole.
An electronic device comprising a substrate, wherein
- the substrate includes
- a first through hole that penetrates a substrate from a first face to a second face of the substrate, and is electrically connected to a transmission line through which a signal is transmitted,
- a second through hole that is provided adjacent to the first through hole in a plan view of the substrate, penetrates the substrate from the first face to the second face, and is electrically connected to a ground, and
- an adjustment unit that adjusts a distance between the first through hole and the second through hole in the plan view of the substrate to adjust an impedance of a connection end of the first through hole with the transmission line,
- wherein a shape of a cross section of the first through hole differs from a shape of a cross section of the second through hole.
A substrate comprising:
- a first through hole that penetrates the substrate from a first face to a second face of the substrate, and is electrically connected to a transmission line through which a signal is transmitted;
- a second through hole that is provided adjacent to the first through hole in a plan view of the substrate, and is electrically connected to a ground;
- and
- an adjustment unit that adjusts an impedance of a connection end of the first through hole with the transmission line, wherein
- the second through hole includes
- a first portion that penetrates the substrate from the first face to a middle of a thickness of the substrate,
- a second portion that penetrates the substrate from the second face to a middle of
- a thickness of the substrate, and
- a dividing portion that electrically divides the first portion and the second portion, and
- the adjustment unit adjusts a length of the dividing portion along a thickness direction of the substrate to adjust the impedance.
