Abstract: A metallic housing forming method includes steps as follows: friction stir welding metallic members to form a metallic housing; immersing the metallic housing in an alkali solution to remove contaminants from the metallic housing, and forming a black salt layer on the metallic housing; stripping the black salt layer away from the metallic housing; electro-polishing the metallic housing to dissolve the outermost surface of the metallic housing; anode-oxiding the metallic housing; and sealing and drying the metallic housing.

Abstract: A support and cushioning device for supporting and holding an electronic device includes a first supporting assembly, a fixed bracket, an adjusting board, and a plurality of elastic members. The adjusting board is mounted to the distal end of the first support assembly. The fixed bracket is elastically mounted to the adjusting board by means of a plurality of elastic members. The fixed bracket includes a base body and a plurality of holding arms extending out from a periphery of the base body. The plurality of holding arms and the base body cooperatively define a holding space for holding an electronic device.

Abstract: A method for inhibiting growth of tin whiskers is provided. The method includes providing a metal substrate, forming a tin layer to cover the surface of the metal substrate, and treating the metal substrate covered the tin layer by an annealing process, wherein the annealing process is performed at 400° C.-600° C. and the surface of the tin layer is subsequently inhibited from growing tin whiskers.
