Land Grid Array

What Does Land Grid Array Mean?

A land grid array (LGA) is an integrated circuit design involving a square grid of contacts that are connected to other components of a printed circuit board. The term refers to a “socket design” where certain components are disconnected from the actual circuit board and integrated into the board’s structure in particularly new ways. In contrast to most other designs, LGA configurations have pins in the socket rather than on the chip.


Techopedia Explains Land Grid Array

Land grid array structures are used for various microprocessors, including some Pentium and other Intel models, as well as AMD chips. This is in contrast to the pin grid array design that is used in the majority of AMD models and some older Intel microprocessors, as well as to the ball grid array design that has also been used for integrated circuits. Industry experts attribute the emergence of LGA to Intel’s LGA platform for Pentium chips during the early millennial years. They also point out that the LGA design can reduce the amount of lead in systems, allowing it to conform to Restrictions of Hazardous Substances (RoHS) directives, while also helping with thermal dissipation.
