Title (EN) CASE, METHOD OF MANUFACTURING THE SAME AND ELECTRONIC DEVICE
(FR) BOÎTIER, SON PROCÉDÉ DE FABRICATION ET APPAREIL ÉLECTRONIQUE
Abstract:
(EN) This application provides a method of manufacturing a case, a case and an electronic device. This method may include providing a metal case (40) with a surface (401); applying a first oxidation treatment on the surface (401) of the metal case (40) to form a first oxidation layer (41); defining a first area (402) on the surface (401); removing a portion of the first oxidation layer (41) located within the first area (402); applying a second oxidation treatment on the surface within the first area (402) to form a second oxidation layer (42); and forming a paint layer (43) on the second oxidation layer (42) by spraying.
(FR) La présente invention porte sur un procédé de fabrication d'un boîtier, sur un boîtier et sur un dispositif électronique. Ce procédé peut consister à fournir un boîtier métallique (40) ayant une surface (401) ; à appliquer un premier traitement d'oxydation sur la surface (401) du boîtier métallique (40) pour former une première couche d'oxydation (41) ; à définir une première zone (402) sur la surface (401) ; à retirer une partie de la première couche d'oxydation (41) située à l'intérieur de la première zone (402) ; à appliquer un second traitement d'oxydation sur la surface à l'intérieur de la première zone (402) pour former une seconde couche d'oxydation (42) ; et à former une couche de peinture (43) sur la seconde couche d'oxydation (42) par pulvérisation.
