The Analysis of the Cracking Mechanism of Miniature Sealed Electromagnetic Relay by SEM
By using SEM and energy spectrum,this paper analyzes the cracking phenomenon of miniature sealed relays in the process of using the orbital riveting technology,explains that the main factors affecting orbital riveting cracking are closely related to the surface carbon content,and gives opinions on the control points of orbital riveting cracking during the product process,which has certain reference significance for solving the problems exist-ing in similar processes.
