Check your manufacturer's requirements. They will give you a minimum trace width/copper clearance. If you're having the supplier assemble the boards for you, generally the through-hole parts are done as a secondary process and the only restriction on spacing is the etch clearance.We are doing a PCB which has both surface mount components and through hole components on it.
The surface mount components are on both sides of the PCB.
What’s the closest that a surface mount pad can be to a through hole pad?
