Abstract: Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

Abstract: Embodiments of this application provide a middle frame, a rear cover, and fabrication methods thereof, and an electronic device. The electronic device may include a mobile or fixed terminal with a frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Ceramics and fiber reinforced composite are used to form frames of a rear cover and a middle frame, to reduce thicknesses of a ceramic outer housing and a ceramic outer frame, thereby reducing a weight of the electronic device.

Abstract: An enclosure of a mobile terminal and a sputter coating apparatus for making the same are provided. The enclosure includes a substrate and a composite film layer coated onto the substrate. The composite film layer has a thickness changing along a first direction. A difference in thickness between any two regions arranged along the first direction of the composite film layer is less than or equal to 350 nanometers. The enclosure has a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers.
