PGA Processor




- 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 pins can then be inserted into the holes in a printed circuit board and soldered in place. They are almost always spaced 2.54 mm (a tenth of an inch) apart. For a given number of pins, this type of package occupies less space than older types such as the dual in-line package (DIP).





Examples of FC-PGA2 Package Type Processors:




- Pentium 4 processor



















- Pentium III processor


























- Intel Celeron processor





























LGA Processor
- Short for Land Grid Array, LGA is the interface used to connect Intel Pentium 4 processors and AMD Opteron to the computer motherboard.
The LGA is a type of surface-mount packaging used for integrated circuits. It can be electrically connected to a PCB either by the use of a socket or by soldering directly to the PCB.
The LGA is used as a physical interface for microprocessors of the
Intel Pentium 4 and AMD Opteron families. Unlike the pin grid array (PGA) interface found on most AMD and Intel processors, there are no pins on the chip; in place of the pins are pads of bare gold-plated copper that touch pins on the motherboard.
