  Pin grid array - Wikipedia, the free encyclopedia
The pin grid array or PGA is a type of packaging used for integrated circuits, particularly microprocessors.
On a PGA, the integrated circuit (IC) is mounted in a ceramic slab of which one face is covered, or partially covered, in a square array of metal pins.
The plastic pin grid array (PPGA) and later flip-chip pin grid array (FCPGA) versions were both created by Intel Corporation for their Pentium processors, and are often used on motherboards with ZIF (Zero Insertion Force) sockets to protect the delicate pins.

 Staggered Pin Grid Array - Wikipedia, the free encyclopedia
Staggered Pin Grid Array or SPGA is a style of socket used on an integrated circuit (IC), usually CPUs.
It consists of two square arrays of pins, offset in both directions by half the minimum distance between pins in one of the arrays.
As with the pin grid array, there is generally a section in the middle of the IC without any pins.

 Method of molding a pin grid array package - Patent 4778641
Pins are secured in position to extend outward from one face of the PW board in the form of a pin grid array of the desired configuration which is typically a plurality of concentric rings thereby creating a square grid pattern of predetermined spacing.
Basically, an array of pins having a standard spacing (for example, 100 mils) is located on a printed wiring (PW) board so that they extend outward from one face for joining with the metal traces on a mother board.
The pins are contacted by metal traces on the PW board that terminate in an array that fronts on the central open area.

 Connection apparatus for interactively accessing an electronic device in a pin grid array socket - Patent 4912401
In those locations where there are no pins associated with the top array, the signal is interrupted between the two boards and may be rerouted and processed before being sent to the bottom board using locations in the pin grid array that are not used by the electronic device.
The pin grid array in the bottom board has pins in all the locations normally used by the electronic device, so that the connection to the environment of the device can be made normally.
Both circuit boards 10,12 are equipped with a pin grid array socket 14,16 or at least a plurality of pin receptacles arranged on a pin grid array layout.

 Making Sense of CPU Packaging
The vast majority of current CPUs are Pin Grid Array (PGA) designs -- chips whose undersides bristle with a grid pattern of pins, which plug into a socket with scores of tiny holes.
PGA processors, like the Pentium 4 shown below, feature a pin-out design that allows the CPU to be installed only one way (usually indicated by a notch or mark on the corner where Pin 1 is located) to avoid electrical shorts or physical damage.
The initials PGA are often preceded by other letters, indicating the many subdivisions or variations of the basic design.

 Pin Grid Array and Variations (PGA / SPGA / CPGA / PPGA)
Pin Grid Array or PGA packaging is the standard used for most second through fifth generation processors, starting with the Intel 80286 over a decade ago.
PGA packages are square or rectangular and have two or more rows of pins going around their perimeter.
PGA packaging was invented because newer processors with wider data and address buses required a large number of interface pins to the motherboard, and DIP packaging just was not up to the task.

 What is FC-PGA? - a definition from Whatis.com - see also: flip chip-pin grid array
FC-PGA (flip chip-pin grid array) is a microchip design developed by Intel for its faster microprocessors in which the hottest part of the chip is located on the side that is away from the motherboard.
In general, PGA (pin grid array) chip packages (or PGA form factors, as they are also called), have 370 PINs "arrayed" in a series of square "grids" at the bottom of the microprocessor.
Currently, two types of PGA chip packages exist for Intel Celeron and Pentium III processors: PPGA (plastic pin grid array) and FC-PGA (flip chip-pin grid array).

 Flip-chip pin grid array - Free net encyclopedia
Flip-Chip Pin Grid Array (FC-PGA or FCPGA) is the package of certain Intel Celeron, Pentium III, and Pentium 4 microprocessors.
The Flip Chip Pin Grid Array is similar to PPGA, except that the silicon core is facing up and the heat slug is exposed.
Pentium 4 processors are also available in Socket 423 Organic Land Grid Array (OLGA) on Interposer (OOI) (INT2 and INT3) and Socket T LGA775 packaging.

 (WO/1999/000836) METHOD AND APPARATUS FOR INSPECTION OF PIN GRID ARRAY PACKAGES FOR BENT LEADS   (Site not responding. Last check: 2007-10-31)
The device holder contacts the central leadless section of the pin grid array and provides a resting place for the pin grid array before an alignment mechanism grasps the pin grid array.
The device holder retracts, and the pin grid array descends into the inspection gauge due to gravity.
If the pin grid array does not lie flatly in the inspection gauge, and is therefore at least partially raised above the inspection gauge, it blocks optical inspection beam, and an output circuit signals the automated operator that the pin grid array has at least one bent lead.

 Flip-Chip Technology on Organic Pin Grid Array Packages
To determine the reliability of these pins, experiments were conducted to evaluate different combinations of pin solder joint structures.
Additionally, pin pull and pin shear testing were used to quantify the pin strength before and after stresses.
Legs with M mg and H mg of SnAg and SnSb legs showed comparable pin pull strength and pin shear strength with the exception of the L mg SnAg lot, which had lower pin pull and pin shear strength.
