WebFailed IC in a laptop. Wrong input polarity has caused massive overheating of the chip and melted the plastic casing. Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical ... WebThe power supply in the chip is distributed uniformly through metal layers across the design and these metal layers have their finite amount of resistance. When we applied the voltage the current starts flowing through these metal layers and some voltage is dropped due to that resistance of a metal wire and current. This drop is called IR drop.
