Integrated circuit damage characteristics

The internal structure, function, and partial damage of the integrated circuit are not working properly. There are also two types of damage to integrated circuits: complete damage and poor thermal stability. When it is completely damaged, it can be removed, and the positive and negative resistance of each pin to ground can be measured compared with the normal integrated circuit. It is always found that one or several of the pins have abnormal resistance. For poor thermal stability, the suspected integrated circuit can be cooled with anhydrous alcohol while the equipment is in operation, and the time of failure is delayed or no longer occurs, and the determination is made. Usually only new integrated circuits can be replaced to eliminate them.
