在工业自动控制设备中,集成电路得到了广泛的应用,尤其是与非门集成电路在设备中的数量往往是不少的,因为用它可以组成各种单元电路,如触发器、振荡器、斯密特电路、单稳电路、分频器、计数器等等。其他集成电路如JK触发器、D型触发器在工业自动控制设备中也用得很多。实践证明,如果集成电路在使用组装前,再进行一次老化与筛选,所装的设备的可靠性 In the industrial automatic control equipment, integrated circuits have been widely used, especially with the number of non-gate integrated circuits in the equipment is often a lot, because it can be used to form a variety of unit circuits, such as flip-flops, oscillators, Schmitt circuits, one-shot circuits, dividers, counters and more. Other integrated circuits such as JK flip-flop, D-type flip-flop in the industrial automation equipment also used a lot. Practice has proved that if the integrated circuit before the use of assembly, and then conduct an aging and screening, the reliability of the equipment installed
