At present, the strength of solder joints and adhesive used to connect components to circuit boards in electronics devices cannot be predicted, and extensive testing and experience are required to design reliable products. This is particularly true for portable devices subject to impact loads if they are dropped.

目前，电子设备中用于连接元件和电路板的焊点和粘合剂的强度无法预测，需要广泛的测试和经验才能设计出可靠的产品。这对于便携设备来说尤其如此，如果它们被跌落，就会受到冲击载荷。
