A pin grid array, often abbreviated PGA, is a type of integrated circuit packaging. In a PGA, the package is square or roughly square, 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, and may or may not cover the entire underside of the package.
PGAs are often mounted on printed circuit boards using the through hole method or inserted into a socket. PGAs allow for more pins per integrated circuit than older packages such as dual in-line package (DIP).
Famous quotes containing the words pin and/or array:
“Suddenly we have a baby who poops and cries, and we are trying to calm, clean up, and pin things together all at once. Then as fast as we learn to cope—so soon—it is hard to recall why diapers ever seemed so important. The frontiers change, and now perhaps we have a teenager we can’t reach.”
—Polly Berrien Berends (20th century)
“Any one who knows what the worth of family affection is among the lower classes, and who has seen the array of little portraits stuck over a labourer’s fireplace ... will perhaps feel with me that in counteracting the tendencies, social and industrial, which every day are sapping the healthier family affections, the sixpenny photograph is doing more for the poor than all the philanthropists in the world.”
—Macmillan’s Magazine (London, September 1871)
