Pin grid array

A pin grid array, often abbreviated PGA, refers to the arrangement of pins on the integrated circuit packaging. In a PGA, the pins are arranged in a square array that may or may not cover the bottom of the package. The pins are commonly spaced 2.54 mm (a tenth of an inch) apart. PGAs are often mounted on printed circuit boards via two methods, through hole or by using a socket. PGAs are primarily used in applications that require more pins than what older packages such as the dual in-line package (DIP).
