An OPGA CPU. Note the brown colour - many OPGA parts are coloured green. The die is in the centre of the device, and the four grey circles are foam spacers to relieve pressure from the die.

The Organic Pin Grid Array (OPGA) is a type of connection for integrated circuits, and especially CPUs, where the silicon die is attached to a plate out of an organic plastic which is pierced by an array of pins which make the requisite connections to the socket. A pin grid array, often abbreviated PGA, refers to the arrangement of pins on the integrated circuit packaging Microchipsjpg|right|thumb|200px|Microchips ( EPROM memory with a transparent window showing the integrated circuit inside Silicon (ˈsɪlɪkən or /ˈsɪlɪkɒn/ silicium is the Chemical element that has the symbol Si and Atomic number 14 A die in the context of Integrated circuits is a small block of semiconducting material on which a given functional circuit is fabricated An organic compound is any member of a large class of Chemical compounds whose Molecules contain Carbon. Plastic is the general common term for a wide range of synthetic or semisynthetic organic solid materials suitable for the manufacture of industrial products In Computer science an array is a Data structure consisting of a group of elements that are accessed by indexing. A pin is a device used for fastening objects or material together A CPU socket or CPU slot is a connector on a computer's Motherboard that accepts a CPU and forms an electrical interface with it

A popular type of CPU to employ the OPGA is the AMD Athlon XP. Athlon is the brand name applied to a series of different X86 processors designed and manufactured by AMD.
