Pin grid array
 
 
  Topics Pin grid array Topic Home

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 (0.1") apart. PGAs are often mounted on printed circuit board
