DFM - Broken Net

Here's an interesting Broken Net error reported by a fabricator using an ODB++ file generated by Altium.



The DRC checks in Altium found NO opens (Broken Nets)









Examining Net_C401-1 shows where the problem lies: 


















As shown above NetC401-1 is passing across the pad of a capacitor, however there is not a connection dot in the pad.

To fix this problem we need to create separate connecting segments along the net to each pad.



















There are no checks currently built into in Altium to find this reported error.
