Why is high frequency PCB not suitable for vias

2018-11-28 10:44Writer: qyadminReading:

      Via is made of drill hole +pad area around the drill hole.

  Throughout the high speed and high frequency PCBs, a lot vias are obviously negative.

  1)Via will take upwards a lot spaces, which usually is detrimental to PCB Design.

  2)Via because the breakpoint regarding the impedance discontinuity in transmission line, which will cause a new reflection of a sign.
