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.
