Abstract

A ball-grid array (BGA) IC packaging frame of the invention includes a plurality of ball-grid array tin balls formed on the rear surface of a BGA package and a plurality of supporting pads formed on the surrounding of the rear surface. The designed supporting pads can efficiently prevent a non-contact soldering and a short circuit when a BGA IC is mounted on a PCB during manufacturing.
