    need urgent help for Satggered Bga Via dropping

    Green Belt

      Hi All,

       

      i am using the Intel system controller Hub IC and Intel Atom processor Z5xx in Pcb layout design (16.2v allegro cadence tool). This is the Staggered type BGA and this BGA pin pitch is very less. i don't know how we can make the Via's and how we can take the trace's from inside of  this type of BGA.
