Antipad Design

ChinoPR , 12-04-2025, 04:14 AM
Hi! I am working with a VPX backplane connector and high-speed signals. I’m trying to design the antipad for the press-fit connector’s through-hole via. How can I calculate the correct size? Thanks

It is **not** a "via", but through hole pad.
Anti-pad: fabrication limits, clearance limits and any additional clearance for lowering the capacitance.
I do not know of any rules that would make it different for press-fit, but it can be wise to stay away from the minimums.
