PCB Coplanar Strips Calculator
Impedance control is crucial for ensuring the proper transmission of high-speed signals on printed circuit boards (PCBs). When designing PCBs, engineers must carefully consider the impedance of the traces to prevent signal reflections and distortions.
Signal reflections occur when the impedance of a trace is not matched to the impedance of the source or load device. These reflections can cause signal timing errors, noise, and crosstalk. Crosstalk is the unwanted coupling of electrical signals between adjacent traces on a PCB.
Our free impedance calculator for coplanar strips can help you with your design features to ensure your PCB is a working as you intend. Instructions are below the calculator and don’t forget we can make and test your controlled impedance printed circuit boards too.
Don’t forget to check out our other calculators on our site and also our material search tool. If your struggling to find the correct results, perhaps switching to a different substrate might help? Click the brown (left) button below to search through a database of over 300 different substrates to find the one with the correct DK value.
