Application of High Temperature Strength Margin Analysis Based on JMP
For the determination of the initial value of high temperature strength of electronic products,there is still a lack of an effective scientific analysis method associated with the reliability index. The initial value of high temperature strength is determined by the high temperature strength margin,it determines the stepping stop temperature point in the high temperature stress step-up-stress test,and also determines starting temperature point in the high temperature stress step-down-stress test. Based on the principle of reliability science of margin reliability,combined with the theory of stress-strength interference model,the initial value of high temperature strength is obtained by using Monte Carlo method and JMP tool,which is used to guide the design of high temperature stress step-stress test profile,so as to put the product reliability index requirements into the actual reliability test of the product,and realize the scientificity and rationality of the reliability test profile design.
