The Layer Stack Manager has configured the Top Layer in Weight like 1/2oz, in my case I am using 1oz. Will that be a problem at the momenten-USTelligent Community 13Tue, 21 Dec 2021 11:42:48 GMThttps://devzone.nordicsemi.com/thread/344576?ContentTypeID=1Tue, 21 Dec 2021 11:42:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a90c791b-7e9a-4057-9316-b31d82816294ketiljo<p>If you have transmission lines on the PCB, you can re-calculate the width with your parameters. You can use for instance Appcad&nbsp;<a href="http://www.hp.woodshot.com/">http://www.hp.woodshot.com/</a>&nbsp;Select &quot;coplanar waveguide&quot; and insert your measurements. Remember to set the PCB material to RF4.</p><div style="clear:both;"></div>
