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.

Flip Chip Pin Grid Array
FC-PGA

(FC-PGA) The package of certain Intel
Celeron and Pentium III processors. FC-PGA processors fit
into Socket 370 motherboard sockets.

The Flip Chip Pin Grid Array is similar to PPGA, except
that the silicon core is facing up and the heat slug is
exposed.

FC-PGA packaging is used by Pentium III processors, and
Celeron 566 processors onward. Earlier Celeron processors
used PPGA packaging.

Celeron processors are also available in Slot 1 SEPP
packaging and Pentium III processors in Slot 1 SECC2
packaging.

Adapters are available to allow a PPGA Celeron to plug into
a Slot 1 connector.

PPGA

(PPGA) The package used for certain
Intel Celeron processors. PPGA processors fit into
Socket 370 motherboard sockets.

The Plastic Pin Grid Array packaging is similar to that used
on Pentium processors. The silicon core is covered by a
heat slug that faces down toward the motherboard.

The Celeron 300A to the 533 use a PPGA package. The Celeron
566 onward use a FC-PGA package.

Celeron processors are also available in Slot 1 SEPP
packaging.

Staggered Pin Grid Array
SPGA

(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.
