 Hi, 
    
          Thanks for ur reply...
    
           In my design i am using 0.5 mm pitch BGA. I am using 5 mil
drill via. I am using Blind Buried vias also. 

             is it possible to manufacture in INDIA....?

        well,
        question again now is whether you want those via holes filled
with conductive or non-conductive epoxy? or you just want to leave it as
it is...
         
        Yes, Hi-Q can do via on pad, but they have a limit on drill size
of 8 mils. So if your BGA is 0.5mm and you are planning to go for via in
pad, i guess it might not work for u.

                        Yes HI-Q Electronics Bangalore does that.

                        Via in Pad may reduce the number of layers
required to accomplish the dense routing. It can also reduce the via
discontinuity presented in the breakout region.
                        
                        Via in pad however, increases the manufacturing
cost as all the manufacturer do not have that capability.
                        
                        Usually via in pad may be an essential
requirement if your BGA pitch is 0.5 mm or less. If the BGA pitch is
0.65 mm or larger you may not need Via in pad.

for PCB Designers", by Vikas Shukla available at Amazon.
                        
                        If you want more information you may search for
the relevant expert at http://ezdia.com <http://ezdia.com/>  and ask the
question to the expert.
