本文通过两个例子讨论了如何使用结构函数来分析半导体封装内部的热特性,或者说任何复杂电子系统的热特性。结构函数还能用于其他应用,例如:获得多芯片封装的热测量,在不同环境条件下对封装中的TIM 进行系统内测试,利用温度和功率循环为可靠性分析提供数据,以及测试交流驱动 LED 等。
现在可以提供这些功能的测试设备软件包括:Simcenter T3STER 瞬态热分析系统,用于分析 LED 的 Simcenter TERALED™ 软件,用于测试 TIM 的 Simcenter DYNTIM,以及用于实验室中或车间的功率循环和封装测试的Simcenter Micred™ Power Tester 软件。
