0603 resistor pad smaller than physical resistor
« on: July 05, 2016, 07:41:52 pm »
Hi,
Is it normal that high density pads are narrower than resistor (footprints generated with Altium IPC compliant footprint wizard)
Pictures attached

No that seems wrong to me. The pad must be at least as wide as the terminal. If I remember correctly, a tiny bit wider even for IPC "least" (i.e. high density) footprints.

A quick search gave me this IPC calculator at their official site, it might help: http://www.ipc.org/ContentPage.aspx?pageid=Land-Pattern-Calculator

But do check if you entered the right dimensions into Altium's calculator. And also check if your 3D body has the right dimensions. Just to make sure you're not chasing the wrong error ;)

Side fillet can be -0.03mm.
