对QFN软件包MSL-1性能的表面增强的铅框架的模具优化
UAD Flat No-Leads（QFN）半导体软件包代表了最稳定的芯片载体类型之一，预计随着原始设备制造商（OEMS）努力将更多的信号处理放入较小的空间中，它们可以继续生长。由于其低调的凝结外形，高I/O和高热量耗散，它们是芯片套装固结，小型化和具有高功率密度的芯片的流行选择，尤其是对于汽车和RF市场。与任何软件包一样，可靠性至关重要，并且由于其广泛接受，OEM，集成设备制造商（IDM）以及外包的半导体组装和测试供应商（OSAT）的需求持续提高QFN的可靠性。
芯片粘接样品制备对 MEMS 传感器应用测量机械性能的影响
摘要 — 计算建模通常用于设计和优化电子封装，以提高性能和可靠性。影响计算模型准确性的因素之一是材料性质的准确性。特别是微机电系统传感器，通常对封装中材料性质的细微变化极为敏感。因此，即使由于样品制备方法或测试技术不同而导致的材料特性测量值出现微小变化，也会影响用于设计或分析传感器性能的计算模型的准确性。对于需要固化的材料，材料特性的挑战更大。例如，芯片粘接聚合物在制造过程中具有严格的固化曲线要求。这种固化条件通常很难在实验室中复制，并且用于材料特性分析的样品不一定代表最终产品中的实际组件。本研究调查了温度固化曲线、固化过程中施加的压力以及样品制备技术等参数对两种芯片粘接弹性体随温度变化的热机械性能的影响。使用动态机械分析和热机械分析等一系列技术测量芯片粘接材料的机械性能，包括弹性模量 (E)、热膨胀系数和玻璃化转变温度。分析针对与典型传感器应用相对应的宽温度范围进行。结果表明，样品制备和表征技术对测量有相当大的影响，从而通过计算建模得出不同的 MEMS 传感器性能预测。
