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.

PGA
(1) (Professional Graphics Adapter) An early IBM PC display standard for 3D processing with 640x480x256 resolution. It was not widely used. See CGA, EGA and VGA.(2) (Programmable Gate Array) See gate array and FPGA.
(3) (Pin Grid Array) A square chip package with a high density of pins (200 pins can fit in 1.5" square), enabling it to support a large amount of I/O. PGAs are typically ceramic (CPGA), but plastic cases are also used (PPGA). The underside of a PGA package looks like a "bed of nails." In a staggered PGA (SPGA), the pins do not line up in perfect rows and columns. See ZIF socket.
