Integrated circuit detection method [Copy link]

Editor's note: Although there are ways to replace integrated circuits, disassembly is troublesome after all. Therefore, before disassembly, you should accurately determine whether the integrated circuit is indeed damaged and the degree of damage to avoid blind disassembly. This article introduces the methods and precautions for off-circuit and on-circuit detection of integrated circuits using only a multimeter as a detection tool. The four methods of on-circuit detection described in the article (measurement of DC resistance, voltage, AC voltage and total current) are practical and commonly used detection methods in amateur maintenance. Here, we also hope that everyone can provide other practical (integrated circuit and component) identification and detection experience.
