Hello, I was wondering what the best way to create an open copper area for a spring pin connector would be. Here are the spring pin connectors that I'm looking to use: [https://www.digikey.com/product-detail/en/mill-max-manufacturing-corp/0965-0-15-20-80-14-11-0/ED1649-ND/2784013](https://www.digikey.com/product-detail/en/mill-max-manufacturing-corp/0965-0-15-20-80-14-11-0/ED1649-ND/2784013) I'm trying to replicate these lightsaber connectors seen here: [https://www.thecustomsabershop.com/V2-NeoPixel-PCB-connector-and-pin-set-11-Pins-P1397.aspx](https://www.thecustomsabershop.com/V2-NeoPixel-PCB-connector-and-pin-set-11-Pins-P1397.aspx) Essentially, there is a bare metal ring that the spring pin is pressed against to make a connection. Then, the side with the spring pin is locked in place. What I need to do is create that open copper bare spot so that the spring pin connector can make contact. I'm not really sure what the best way to do that is.
