在微型计算机的电路中,一般都大量使用了集成电路芯片,这些芯片所起的作用是对电信号进行处理和控制。因此,多数芯片是电路中的核心元件。由于集成芯片内部电路复杂,芯片的引脚较多,当芯片发生故障时,要想查找出故障芯片和更换故障芯片就比较麻烦。笔者经过多次检修集成芯片,获得了一些比较实用的经验,在这里提供给同行们,以期共同交流。 In microcomputer circuits, integrated circuit chips are commonly used in large quantities and the role of these chips is to process and control electrical signals. Therefore, most chips are the core components of the circuit. Due to the complicated internal circuit of the integrated chip and the more pins of the chip, when the chip fails, it is troublesome to find the failed chip and replace the failed chip. After several maintenance I integrated chip, access to some more practical experience, available to colleagues here, with a view to common exchanges.
