Hello everyone,
I have to make jumper pads for 20 Ga wire jumpers. The spec for the wire is 32 mils ( .812mm). Should I just go one size larger (18 Ga..
40 mil) or larger?I appreciate everyone's advice.

Thank you!
As a rule of thumb, I just up the diameter from 25% to 50%... With 50% being used on small wires, and 25% on large wires.
Don't just add a fixed amount of oversize because on larger wires you will find they are too tight to rework, and smaller wires the parts are too loose.

Always leave at least 5 mils minimum of "slop"; 2 mils for hole tolerance and 3 mils for easy insertion (or removal if rework is needed). 40 mils is fine.
