Some studies indicated that the fatigue life of BGA is less than QFP. I realized that there are many variables involved in determining long term reliability. Any comments on this subject would be highly appreciated. The ranking for culmulative joint fails as I know it: 1. 15 mils QFP (longest fatigue life) 2. CCGA 3.
