Investigating the fracture of electronic boards in space systems under random vibrations

Zahra Khaji; Mahdi Fakoor; Saeed Shakhesi

Articles in Press, Accepted Manuscript, Available Online from 16 August 2023

https://doi.org/10.22034/jssta.2023.391116.1117

Abstract
  The design of space operations must be done carefully. Because the smallest mistake in the design and construction of the spacecraft causes heavy financial losses. Electronic boards are one of the most important components of electronic systems in any operation. These boards must continue to operate ...  Read More
