摘要
A ball grid array (BGA) includes a plurality of metal balls adapted for connection between an electrical circuit and a substrate. A first portion of the BGA contains a first group of the metal balls arranged according to a first pitch. A second portion of the BGA contains a second group of metal the balls arranged according to a second pitch that is less than the first pitch, to provide increased metal contact area and correspondingly enhanced thermal transfer capability.
