gEDA-user: Different DRC rules for pins and vias

[Jasper <funkybob@xxxxxxxxx>]

Hello,

It appears that in PCB the DRC check for minimum annular ring is
different for pins and vias. For pins the equation for not passing is:

Pad - Hole < 2 * Ring

For via it is:

Pad - Hole < Ring

Thus when the minimum annular ring is 20 mils, a via with size 30 / 10
mils will pass, but a pin will not. Is this intentional? The via check
seems more logical to me.

Jasper
