    摘要: Disclosed are an electronic device including a housing having a matte surface and a method of manufacturing the same. An electronic device according to various embodiments of the disclosure is an electronic device including a housing. The housing may include a base material including an aluminum alloy, a plurality of pits adjacently formed on a surface of the base material, and a crystal grain boundary protrusion part formed as a crystal grain boundary of the surface of the base material portion protrudes on the surface. A method of manufacturing a housing for an electronic device may include an etching step of generating irregularities on a surface of a base material including an aluminum alloy in a way to etch the base material by dipping the base material into an etching solution containing chloride ions, and an anodizing step of forming an anodizing layer on the surface of the base material by dipping, into an anodizing solution, the base material on which the etching step has been completed and applying a current to the base material by using the base material as an anode.

    摘要: The present invention discloses a device and method for preventing copper plating of a conductor roll in the technical field of manufacturing of copper electroplating films. A conductor roll and an electroplating anode are respectively connected to the negative output end and the positive output end of a first power source, the conductor roll and the electroplating anode electroplate a plating product flowing through plating pool bath after being electrified, and the conductor roll is connected to the positive output end of a second power source and mated with an auxiliary electrode connected to the negative output end of the second power source to realize the electrolysis of the conductor roll so that the conductor roll avoids copper deposition when electroplating the plating product. The present invention can realize the electrolysis of bath near the conductor roll on the premise of completing electroplating by the conductor roll so that the copper electroplating process and the copper electrolyzing process are balanced on the conductor roll to avoid residual copper on the conductor roll so as to improve the copper plating quality of the plating product, and the present invention does not increase the procedure of the electroplating process or affect the implementation of the electroplating process.

    摘要: In-plane uniformity of a membrane electroplated on a polygon substrate is improved. An electroplating device includes an anode holder configured to hold an anode, a substrate holder configured to hold a polygon substrate, and a regulation plate provided between the anode holder and the substrate holder. The regulation plate has a body portion having a first polygon opening following an outer shape of the polygon substrate, and wall portions protruding on a substrate holder side from edges of the first polygon opening. The wall portions protrude over a first distance on the substrate holder side in first regions which contain middle portions of sides of the first polygon opening, and are notched in second regions which contain corner portions of the first polygon opening, or protrude over a second distance smaller than the first distance on the substrate holder side.
