The reasons for electronic chip damage are as follows: power supply exceeds the standard, voltage and current overload damage; Electrostatic damage; Programming protection, resulting in inability to erase.
There are many other factors that can damage the chip, such as whether electrostatic protection is done, the humidity of the chip storage, whether the temperature meets the requirements, whether the temperature of the chip welding is too high, to improve the rate of good products, it is necessary to do work from many aspects, of course, can not ignore the above details that are not easy to pay attention to.
The electronic chip itself is aging and its quality is faulty External damage The working voltage is too high The working temperature is too high during welding the temperature is too high for a long time Power shock (static electricity, lightning strikes, or power pulse when the power supply is faulty)
