SPGA         
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?). See also SPGA.

Staggered Pin Grid Array         
<hardware> (SPGA) A style of integrated circuit socket or pin-out with a staggered grid of pins around the edge of the socket, positioned as several squares, one inside the other. SPGA is commonly used on motherboards for processors, e.g. Socket 5, Socket 7 and Socket 8. See also PGA. [Better description?] (1999-08-04)

Pin grid array

A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are arranged in a regular array on the underside of the package. The pins are commonly spaced 2.54 mm (0.1") apart, and may or may not cover the entire underside of the package.

PGAs are often mounted on printed circuit boards using the through hole method or inserted into a socket. PGAs allow for more pins per integrated circuit than older packages, such as dual in-line package (DIP).
