Good afternoon,

Google search engine (http://www.google.com) might be very useful for you :) Much has been written on the net about the topic you are asking. So the search keys will be �X-Ray� and �Voids�. For instance: http://www.aciusa.org/leadfree/leadfree_biocca11-5-04.htm

BR, Pavel

Hello. What kind of void are you seeing? You said the part was a BGA, is it being underfilled or is it a solder void?
