Abstract
(EN)
The present invention relates to a metal component comprising: a first metal component including a cage; an electronic component located in the cage; and a second metal component formed on the first metal component, wherein the first metal component comprises an elongated first dendritic fine structure extending in a z-axis direction, the second metal component comprises an elongated second dendritic fine structure extending in the z-axis direction, and an interface between the first metal component and the second metal component comprises a fine structure extending in the widthwise direction. Via a step-by-step 3D printing process, anisotropy of the fine structure can be attenuated by intentionally forming a fine structure extending in the widthwise direction, and disconnecting a dendritic fine structure extending in the z-axis direction.

La présente invention concerne un composant métallique comportant : un premier composant métallique comprenant une cage ; un composant électronique situé dans la cage ; et un second composant métallique formé sur le premier composant métallique, le premier composant métallique comportant une première structure fine dendritique allongée s'étendant dans une direction d'axe z, le second composant métallique comportant une seconde structure fine dendritique allongée s'étendant dans la direction de l'axe z, et une interface entre le premier composant métallique et le second composant métallique comportant une structure fine s'étendant dans la direction de la largeur. Par l'intermédiaire d'un processus d'impression 3D pas à pas, l'anisotropie de la structure fine peut être atténuée par la formation intentionnelle d'une structure fine s'étendant dans le sens de la largeur, et la déconnexion d'une structure fine dendritique s'étendant dans la direction de l'axe z.
