1mm BGA routing

[MSchaeffer]

I'm working on a 6 layer board with a 1mm pitch BGA in PCB123. All of my vias under the BGA are in violation of the DRC and my surface traces are as well. Will this board be produceable by Sunstone despite the violation to the DRC? If so, is there any way to change the DRC so to a more accurate level so i can avoid all of the errors while still maintaining produceability? If not, any tips? Thanks

Please note that orders through PCB123 have a minimum trace and space of .007"

You should be able to route a 1 mm bga with PCB123. You will need to allow your via to share some space with the bga pad as shown in the image below.

Use the smallest hole size .014" with the smallest via pad size .025" (only available when a multi-layer board is selected) and you should be able to route using7 miltrace with a 6 mil space. You can order this directly through PCB123. This will only work if your bga pads are about .5 mm diameter.
