摘要
以ＰＢＧＡ 焊点形态成形ＣＡＤ和焊点热疲劳寿命可靠性ＣＡＤ研究为例，提出ＳＭＴ 焊点形态成形和可靠性一体化设计思想，并对其实现方法进行了分析研究，给出了具体实现步骤和研究结果．
PBGA solder joint is taken as example for CAD study of solder joint evolving and thermal fatigue life,integration design thought of solder evolving and reliability is presented.After realization method is analyzed,realization process in detail is provided and results are shown.
