Accelerated life testing is one of the rapid verification methods for highly reliable electronic products in complex service environments. Existing acceleration models primarily rely on single or doable stress, making it difficult to meet the reliability improvement needs of highly reliable electronic products in terms of fault excitation efficiency and service environment simulation accuracy. This article proposes a vector representation method for the multi stress acceleration factor of highly reliable electronic products based on the random vector theory and product failure time model, considering the multi stress coupling effect in the product failure mechanism to improve the accuracy of the multi stress acceleration model when describing the product failure mechanism. The method was applied to statistically analyze the temperature, humidity, and electrical stress constant acceleration life test data of power control components under 5 different stress combinations. The predicted results of the model showed an error of less than 10% compared to the test results, verifying the scientific and feasible vector characterization of multi stress acceleration factors in highly reliable electronic products and providing a method for the research of multi stress acceleration test technology in electronic products. © 2023 IEEE.

engineering nanomaterials at single-atomic sites could enable unprecedented catalytic properties for broad applications, yet it remains challenging to do so on the surface of multimetallic nanocrystals. Herein, we present the multifactorial engineering（size, shape, phase, and composition） of the fully ordered Pt Bi nanoplates at atomic level, achieving a unique catalyst surface where the face-centered cubic（fcc） Pt edges are modified by the isolated Pd atoms and Bi Ox adatoms. This Pd1/Pt-Bi Ox electrocatalyst exhibits an ultrahigh mass activity of 16.01 A mgPt+Pd-1toward ethanol oxidation in alkaline electrolyte and enables a direct ethanol fuel cell of peak power density of 56.7 mW cm-2. The surrounding Bi Ox adatoms are critical for mitigating CO-poisoning on the Pt surface, and the Pd1/Pt single-atom alloy further facilitates the electrooxidation of CH3CH2OH. This work offers new insights into the rational design and construction of sophisticated catalyst surface at single-atomic sites for highly efficient electrocatalysis.
