Pin Grid Array (PGA) is a type of surface-mount packaging primarily used for integrated circuits, especially in micro processors. In a Pin Grid Array, the under side of the package has an array of pins that are meant to insert into a socket containing a matching array of holes.^[1]

This setup allows for strong physical and electrical connections. PGA is often famous for its long run and ease of replacement, but it’s pins can be fragile and prone to bend or damage during handling. PGA is commonly use in older or less performance intensive applications.
