  OFFICE MEMO         Via in Pad for BGA                    Date:  1997.11.24

Hello Technetters,

I am researching the possibility of puttings vias in pads for BGA.

Is anybody using "Via in Pad" for BGA ?
What are the implications (pros/cons) of using "Via in Pad" for BGA ?
Is the type of BGA (PBGA/CBGA/TBGA) of importance ?
(I am especially interested in non-microvia applications).

Thanks in advance.
