Closeup of the pins of a pin grid array The pin grid array at the bottom of prototype Motorola 68020 microprocessor The pin grid array on the bottom of an AMD Phenom X4 9750 processor that uses the AMD AM2+ socket. A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are ...
CPUs with a PGA (pin grid array) package are inserted into the socket and, if included, the latch is closed. CPUs with an LGA (land grid array) package are inserted into the socket, the latch plate is flipped into position atop the CPU, and the lever is lowered and locked into place, pressing the CPU's contacts firmly against the socket's lands ...
Organic ball-grid array [3] TFBGA: Thin fine-pitch ball-grid array [3] PBGA: Plastic ball-grid array [3] MAP-BGA: Mold array process - ball-grid array : UCSP: Micro (μ) chip-scale package: Similar to a BGA (A Maxim trademark example) [17] μBGA: Micro ball-grid array: Ball spacing less than 1 mm LFBGA: Low-profile fine-pitch ball-grid array [3 ...
LGA 1700 socket on a motherboard. The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) — as opposed to pins on the integrated circuit, known as a pin grid array (PGA). [1]
Pins arranged in a 36 × 35 grid array; 18 × 15 size grid removed from the center; Utilization of cam actuated retention mechanism; The r in rPGA refers to "Reduced pitch" which is 1mm × 1mm in this socket design. [5] Socket G1 systems can only run in dual-channel memory mode, compared to the triple-channel mode of LGA 1366, as a result of ...
Socket 495, also known as μPGA2, is a CPU socket used for the Intel Pentium III and Celeron mobile processors.This socket was also used in Microsoft's Xbox console for the Xbox CPU, albeit in a BGA (ball grid array) format.
This was the last Intel desktop socket to use a pin grid array interface. All later Intel desktop sockets use a land grid array ( LGA ) interface. Socket 478 was phased out with the launch of LGA 775 in 2004.
Socket rPGA 947 has one extra pin hole, other than that it is identical to socket G3. It is the last pin grid array socket for Intel's mobile processors - all mobile processors in microarchitectures succeeding Haswell are exclusively available in BGA packaging. AMD also adopted the same practice, starting with their Steamroller microarchitecture.
