Pin Grid Array

(hardware)

Pin Grid Array - (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?). See also SPGA.
