PCBWay will enjoy the holiday on Oct 1st to Oct 3rd. All orders still can be placed. However, the delivery date shall be postponed as the express company will pick up the package after Oct 3rd.

 

PCB Prototype the Easy Way

Full feature custom PCB prototype service.


Impedance Calculation

With PCBWay impedance calculator, you can calculate the approximate impedance of your PCB / high frequency circuit board. The surface finish is neglected. We recommend the software from Polar Instruments if you want to get exact impedance calculation.
Note: The results are only for approximation and rough estimation, the final values and the corresponding layer construction have to be calculated by us. The stackup information check here.
Instructions: Please select the value to be determined. You can then adjust the other parameters according to your needs.
