Masked Vias?

I remember seeing a post on the forums recently, but I can’t find it now, so apologies if this is a dupe.

I notice Sparkfun boards usually have soldermask over the vias. Is there any way to accomplish this with Eagle / BatchPCB?

…Or is this the default?

In Eagle there a way to unmask vias.

Click on the TOOLS header and select DRC.

Select the MASKS tab and then set the LIMIT line to “0”.

That will force all vias to have sold mask removed from the etch. IF you make the limit value greater than the largest drill then all vias under that limit will have solder mask removed.

James has it partially right with setting the limit to “0”. However, if you set the limit greater than the largest via drill, then all vias will be masked. For example, if your vias are .020", set the limit to .021".
