0201 Capacitor Corner Radius Pad

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,
I created my first 0201 capacitor and I feel that using a Corner Radius Size Limit parameter= 0.10 mm could be "risky" (I used Fab Tol= 0, Placement Tol=0).

I know that some manufacturers use 0.05 mm.

My component is GRM033R61C104KE14D from Murata

Which is your recommendation for this tiny component sizes?

Waiting for your comments.

David

	Rule of thumb - any package less than 1.00 mm in length or width should have 0.05 mm corner radius pads. You can use the 'SMD Pad Stack Rules' in the side panel of the calculator to change the corner radius. Or you can move the calculator footprint to FP Designer to permanently save the 0.05 mm corner radius to FPX library format. But we recommend that you first setup everything in the calculator before moving to FP Designer so you won't have to edit the pad stack in FP Designer. FP Designer saves all your settings to the FPX library. You can rename the Footprint Name in the Library Editor.
