    Centering Clines Within BGA Reply

     Hello experts,

    Is there a function that I can use to center only the clines inside the BGA area?

    If so how do go I about it?

    For instance, what skill code can I use to shove/move single clines or dual clines in between (or in the middle of) the BGA vias?

      - where if there are two clines in between vias, the air gap is 1x or 2x of the trace width.

    Below is a simple illustration:

     

    Single cline centered in between BGA vias:

    o I o I o I o

    Dual CLine centered in between BGA vias::

    o IxI o IxI o

     

    Where:

    o = via

    I = Cline

    x = air gap between two clines.

     Note:

    In some areas of the BGA, the vias are in-line while in some areas (at the periphery) the via pitch is mixed, that is a combination of 10mm and 8mm  - stagered pitch.

     Thanks,

    Eddie

    Route--->Custom smooth (Enable only Cline segs on find window)  option may working for you,if u set the Spacing constraints values properly.

     Thanks Prashanth for the feedback.

    Yes, I can use this option IF the BGA pitch is the same on all vias. However in my design I have different bga pitch so using different setting will be very difficult. I was looking for a code where the pitch (distance) between vias is used to place clines mid-center.
