とができるという効果がある。[Effects of the Invention] As explained above, the present invention brings the signal pin into contact with the surface pad of the printed wiring board by utilizing the elasticity of the elastic component.
Because they are electrically connected, surface pads have a smaller capacitance than through holes, and have the effect of reducing waveform rounding and distortion.

も面積が一定ならほとんど変化しないので、スルーホー
ルのようにプリント配線板の暦数が多くなると容量が増
え、波形のなまり、歪みが大きくなることはない。In addition, the surface pad will hardly change even if the printed wiring board has a large number of calendars if its area remains constant, so when the number of printed wiring boards increases, such as through holes, the capacitance will increase and the waveform will become rounded and distorted. It never gets bigger.
