Impedance Controlled PCB


  • Both characteristic impedance and differential impedance are manageable.
  • By using TDR gauge, we can handle prototype level impedance control to mass production manufacturing process monitoring.
  • Our support begins from development stage to suite the needs of customers quickly.
