How to Route Your PCB in OrCAD PCB Editor 17.4

When I create a fanout the traces are so thin. How can i fix this? thanks

Hi Jason, You can either define a default line width in the physical section of the constraint manager (Setup > Constraints from the menu) or select Override Line Width in the options panel when creating a fanout and define the desired trace width. Hope this helps!

@@EMADesignAutomation Is this something that needs to be changed before the fanout I noticed other students create fanouts and the trace was the same as the video. However, mine were as thin as a line.

Yes, trace thickness will be automatically assigned based on the constraints set in the constraint manager, so constraints should be configured first. Trace thickness can be changed after the fact by selecting Edit > Change Objects from the menu. In the options panel, you can check line width and specify the width, then select the desired traces in the PCB canvas. Setting constraints in the beginning of the design is suggested. This allows you to set rules for different trace requirements (power, differential pairs, etc.). Routing options will then be configured automatically based on the assigned rules.
