BGA or Ball Grid Array PCB

A BGA PCB is a printed circuit board that instead of pins for connection to external circuitry, it has solder ball contacts, which come from the IC's that use that connection technology.

It has the advantage of having high 'pin' density, that other packaging technologies don't have, but a disadvantage is expensive testing of solder joints.

This kind of PCB is mostly use in the connections for CPU's.
