CPGA stands for Ceramic Pin Grid Array, a type of connection for CPUs where the processor's die is attached to a heat-conducting ceramic plate 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 The word ceramic is derived from the Greek word κεραμικός ( keramikos) 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
Popular CPUs that employ CPGA are the "classic" Socket A Athlon and the Duron, both from AMD. Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Athlon is the brand name applied to a series of different X86 processors designed and manufactured by AMD. The AMD Duron was an X86 -compatible Computer processor manufactured by AMD.
