Introduction: Increase Clearance Between the Copper Plane and Signal Trace
I am a hobbyist and I design Printed Circuit Boards (PCB) for my blogs and Youtube Videos. I ordered my PCB online from LionCircuits . It is an Indian company and they have an automated platform for manufacturing. It automatically reviews your Gerber files before they proceed with the Fabrication. I uploaded my Gerber files, got quotation instantly and ordered it online. Within minutes I got feedback about a spacing issue between the copper plane and signal traces. This is a common error that I have seen over time with the design for manufacturing.
It is very important to check the clearance between the copper plane and signal traces as this can cause unintended shorts/ expensive for manufacturing with special requirements.
Usually, this can be simply fixed using the steps below to Increase the clearance between the copper plane and signal traces:
Step 1: Default Isolation
The Default isolation between the copper layer and the signal traces is “6 mil“. You can see the image for the reference.
Step 2: Properties
To increase the clearance right click on the edge of the polygon and go to “Properties“.
In Properties, change the Isolate value to 10 mils, click “Apply“ and then “OK“.
Step 3: Finally
The spaces between the copper layer and the signal traces will increase. You can see the difference in the images given.
