半导体器件 机械和气候试验方法 第40部分：采用应变仪的板级跌落试验方法
Application Summary AI generated
This standard specifies a board-level drop test method for semiconductor devices using strain gauges to measure mechanical stress during impact. It is applied in the electronics industry to evaluate the solder joint reliability and structural integrity of components like ball grid arrays (BGAs) and chip-scale packages (CSPs) mounted on printed circuit boards (PCBs) under drop conditions. The method is particularly relevant for portable electronic products such as smartphones and tablets, where drop-induced failures are a primary concern.
