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] An LGA can be electrically connected to a printed circuit board (PCB) either by the use of a ...
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 ...
Land grid array (LGA): An array of bare lands only. Similar to in appearance to QFN, but mating is by spring pins within a socket rather than solder. Column grid array (CGA): A circuit package in which the input and output points are high-temperature solder cylinders or columns arranged in a grid pattern.
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 arranged in a regular array on the underside of the package. The pins are commonly spaced 2.54 mm (0.1") apart, [1] and may or may not cover the entire underside of the package.
In the late 1990s, plastic quad flat pack (PQFP) and thin small-outline packages (TSOP) replaced PGA packages as the most common for high pin count devices, [1] though PGA packages are still often used for microprocessors. However, industry leaders Intel and AMD transitioned in the 2000s from PGA packages to land grid array (LGA) packages. [8]
Pentium 4 Willamette with Socket 478 (2001), pin side. Socket 478, also known as mPGA478 or mPGA478B, is a 478-contact CPU socket used for Intel's Pentium 4 and Celeron series CPUs.
Socket AM5 (LGA 1718) is a zero insertion force flip-chip land grid array (LGA) [1] CPU socket designed by AMD that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture. [2] [3] AM5 was launched in September 2022 and is the successor to AM4. [4] The Ryzen 7000 series processors were the first AM5 processors.
Socket G1 systems can only run in dual-channel memory mode, compared to the triple-channel mode of LGA 1366, as a result of the lower pin count. See also
