Signal Wiring Board and Signal Transmission Circuit |
摘要 |
The present invention maintains plugging-unplugging durability of connector pins for connecting to a signal wiring board, as well as reduces a stub length of a through hole connecting to a signal wiring. In the signal wiring board according to the present invention, a through hole connecting to the inner-layer signal wiring is formed to be shorter than the other through holes. A through hole in which a connector pin connecting to the inner-layer signal wiring is inserted is formed to have a length corresponding to a depth of the inner-layer signal wiring. |
