Use this template if you're planning to get your multi layer board manufactured in JLCPCB. It has the via min/max and trace width constraints already baked as global rules. #project-template #template #manufacturer-design-rules

Use this spacing tool to set the spacing between your traces for a 90 ohm differential pair - Use "JLC3313" 4 layer stackup - Route on Top with L2 reference or Bottom with L3 reference - Trace width of both traces should be 200um
