Relay substrate and substrate assembly
First Claim
1. A substrate for connecting circuit boards, comprising:
- a substrate member having a first surface and a second surface facing each other and a first end and a second end facing each other;
a first signal line formed on the first surface of the first end;
a second signal line formed on the second surface of the second end;
a third signal line connecting the first signal line with the second signal line;
a first ground plane arranged on the first surface and surrounding the first signal line; and
a portion of the second signal line formed over the first ground, the portion comprising narrower than an other portion of the second signal line.
