Controlled Impedance

Our trained CAD engineers are more than happy to work with you at your design stage on any of your controlled impedance PCBs. 

We can verifying your track and gaps, check your layer builds, and confirm your calculations using our licensed Polar software. Once the boards have been manufactured we will test the additional impedance coupons added onto our manufacturing panels. These coupons match the track and gap requirements as indicated and designed on your PCB and are tested using our Polar CITS Controlled Impedance Test hardware. 

We can then supply test results in a report when delivered with your finished printed circuit boards.

Impedance PCBs are used across a broad range of applications to help ensure high signal integrity. It is the characteristic impedance of the PCB transmission lines that the designer and fabricator are setting out to control.

Impedance is measured in Ohms (symbol Ω) and is an AC characteristic which becomes important as the signal frequency increases, typically becoming critical for PCB traces at signal components of two or three hundred MHz and above.

We have multiple impedance calculators available on our website, click on the pictures below or select one from the menu above.
