Pin Grid Array

hardware (PGA) A style of integrated circuit socket or

pin-out with pins laid out on a square or rectangular grid

with a separation of 0.1 inch in each direction. The pins

near the centre of the array are often missing.

PGA is often used on motherboards for processors, e.g.

Socket 6 and Socket 8.

PPGA is "plastic PGA" (as opposed to ceramic?).
