Calculating method of MTBF for integrated circuit

Abstract

The integrated circuit have a great use in the electronic equipment, and the mean time between failures (MTBF) is an important index to reflect the stability of the system, this paper provides a general method to calculate the MTBF of the integrated circuit contracted to the previous methods. The general rule of integrated circuit failure is first introduced, which satisfies the law of bathtub curve; secondly, verify that the mean time of failure of the integrated circuit satisfy the Poisson distribution. Based on the two conditions, an algorithm of calculating the MTBF of the integrated circuit is provided. According to the mean time of failure of the 74HC00, its mean time of failure is calculated. Finally, verified the reliability of the provided method.
