在面对高强冲击、剧烈振动和高低温冲击等恶劣环境时，对离线存储测试装置中电路系统运行的可靠性提出了更高的要求。为了确保电路系统在恶劣环境中的正常工作，需对存储测试装置中的电路模块进行灌封加固。利用环氧树脂对电路模块进行灌封，形成的电路灌封体在试验过程中时常会出现运行失效的现象。通过分析表明：应力集中是引起电路灌封体失效的主要因素。分析了灌封过程中导致应力集中的原因，并从灌封材料、灌封工艺以及产品设计几个方面对缓解灌封体内部应力集中的方法进行了分析和探讨。

When offline storage test device work in high shock, severe vibration, temperature impact and other harsh environments, the reliability of the circuit system running is extremely important. In order to ensure the circuit system work normally in the harsh environment, the circuit module is reinforced by potting. The circuit encapsulation body which circuit module are potted with epoxy resin often failure operation in test. The analysis result show that stress concentration is the main factor which lead to that. The reason of stress concentration in the potting is analyzed. Furthermore, the method of avoiding stress concentration is discussed from encapsulation material, encapsulation technology and product designing.
