VIA in pad for BGA

Former Member

I am trying to route a board with a BGA. The manufacturer recommended

layout method is to use filled vias directly in the BGA pad. I am

attempting to place a via directly coincident with the BGA pad (using

the ROUTE command and mouse) I get the error: "Can't set via to layer

'16' at (x y)"

 

Where x and y are of course the actual dimensions.

 

My DRC settings are 0mil for any vias and smds and pads of the same signal.

 

I'll try to illustrate this with the attached PNG files if allowed, or

you can see the images at this link: http://imgur.com/a/BgPqU

 

 

 

I appreciate any help.

    I suppose it is a matter of Layer Setup. Could you check the settings

    in the Design Rules? What is the Layer Setup there?
