This served properly for more recent processors with wider Data and cope with Buses. Moreover, PGA is cHeaper than the Ball Grid Array and other grid arrays.

However, the pin connections of the PGA are regularly less dependable and the PGA era additionally had sure limitations on thermal and electric skills. These drawbacks Finally resulted inside the PGA being step by step replaced with the aid of different standards which includes the ball grid array.
