Geometry Too Small for Silkscreen Outline

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

   Hello,
I'm new to the tools and PCB footprint design in general and I haven't had any luck searching for this in the forum so far. I'm creating a simple 0603 footprint for a PPTC fuse and I'm getting the attached warning after calculating:

I have "Use manufacturer's recommended dimensions" UNCHECKED, so this calculation should be the IPC-compliant version of the footprint. I would think it would be possible to fit the silkscreen annotations in a 0603 footprint, no? 

My relevant drafting settings are as follows:

Thank you in advance for your help.

Chris

	The silkscreen outline is auto-generated by your Option Settings. If Footprint Expert only obeys your rules. To small is to small to obey your rules. You have 2 options. Add a Drafting Outline > Rectangular > Silkscreen > your x/y dimensions - then save to FPX library Move the chip from the Calculator to FP Designer. FP Designer auto generates a silkscreen outline if the rules are violated.
