A Coefficient Method for Calculating the Reliability of Functional Part of Power Supply Pcb 56_14.pdf

The reliability of electronic equipment has been the focus of the attention for many decades. The actuality of that grows along with the miniaturization of electronic components and the density of attachment in electronic equipment. The process of reliability calculation becomes more complex and takes more time in view of the growth of type and amount of applied electronic components. Nonfailure operating probability, failure intensity, and mean time to failure are basic qualitative characteristics of the reliability. The dangerous failures of electronic components can have critical and catastrophic consequences in the functionality of electronic equipment. The article deals with the procedure of the reliability calculation using various coefficients. Different mathematical models can be used for the same task of the reliability calculation. In order to solve the tasks, various methods can be used. All these facts may cause different results.Authors represent an approach to the coefficient method allowing to carry out the reliability calculation with higher precision and fidelity. The coefficient method is usable for comparing different ways for reliability calculation.
