Manufacturing of ball grid array (BGA) packages is composed of many steps and requires a substantial investment in capital equipment and materials. Currently, plastic substrate BGAs are the standard within Motorola. The packages have demonstrated enhanced performance in harsh environmental conditions: liquid-to-liquid thermal shock, air-toair temperature cycling, elevated temperature/high humidity/bias, drop testing, flexure, high tempera~ ture storage, high temperature operating, autoclave, and multiple reflow.
