A motor drive electronics assembly for Mars Curiosity Rover: An example of assembly qualification for extreme environments

This paper describes the technology development and infusion of a motor drive electronics assembly for Mars Curiosity Rover under space extreme environments. The technology evaluation and qualification as well as space qualification of the assembly are described and summarized. Because of the uncertainty of the technologies operating under the extreme space environments and that a high level of reliability was required for this assembly application, both component and assembly board level qualifications were performed.
