贴片集成电路在电子设备中通常为核心部件,故障率较高。对其进行的检测方法有多种,这里只介绍两最基本的检测方法,其他检测方法请读者参阅相关文献资料。1.电压检测法该法是检查贴片集成电路最为有效和常用的检测手段,且由于测量时万用表并联在电路中,无须改动电路,所以操作相当方便。具体操作方法如下。(1)找出贴片集成电路的标准工作电压数据。通 Chip integrated circuits are often the core components in electronic equipment, with high failure rates. There are a variety of detection methods, only the two most basic detection methods introduced here, other detection methods, readers refer to the relevant literature. 1. The voltage detection method The law is to check the most effective chip integrated circuits and commonly used detection means, and because the multimeter parallel measurement in the circuit, without changing the circuit, so the operation is quite convenient. Specific methods of operation are as follows. (1) Find out the standard working voltage data of the chip integrated circuit. through
