Abstract: The present disclosure relates to the technical field of metal materials, and more specifically, to a non-heat treated aluminum alloy stress-bearing member material with high toughness and high casting performance and its preparation method. The non-heat treated aluminum alloy stress-bearing member material with high toughness and high casting performance includes the following components in terms of mass percentage: Si: 8.5-12.0%, Mg: 0.10-0.35%, Mn: 0.25-0.4%, Cr: 0.02-0.14%, V: 0.02-0.38%, Sr: 0.01-0.04%, Ti: 0.05-0.11%, B?0.005%, Ca?0.05%, Zr?0.1%, Zn?0.1%, RE?0.1%. The total amount of other impurities is less than or equal to 0.25%, and the balance is Al. Under the premise of ensuring that the alloy has good die casting performance, the die-casting parts in non-heat-treated state can have excellent comprehensive mechanical properties, thereby meeting the performance requirements of the die casting stress-bearing member.

Abstract: This application provides an electronic device. The electronic device comprises a first component, a second component and a circuit board. The circuit board includes a main board, a first type of solder pad, and a second type of solder pad. Both the first type of solder pad and the second type of solder pad are formed on a surface of the main board, and are electrically connected to the main board. The first type of solder pad includes a first solder pad and a first common solder pad, and the second type of solder pad includes a second solder pad and the first common solder pad. The first solder pad and the first common solder pad are configured to be simultaneously connected to the first component, and the second solder pad and the first common solder pad are configured to be simultaneously connected to the second component.

Abstract: A flexible display panel includes a main view portion, and a first side view portion, a second side view portion, and a third side view portion that are disposed at an edge of the main view portion, where the third side view portion is connected between the first side view portion and the second side view portion; and the first side view portion, the second side view portion, and the third side view portion respectively extend from a first section, a second section, and a corner section of the main view portion in a direction leaving a middle portion of the main view portion and bend toward a back face side.

Abstract: An electronic device includes a rear cover and a camera decoration component. The camera decoration component includes a decoration member, a dial plate, a plurality of positioning members, and a plurality of induction members. The dial plate is annular, and is sleeved on an outer peripheral side of the decoration member. The decoration member includes a virtual rotation axis, and the dial plate is rotatably connected to the decoration member. The decoration member is configured to rotate around the virtual rotation axis of the decoration member. The positioning members and the induction members are configured to control the dial plate to be in a hovering state.
