Abstract: This application provides a printed circuit board assembly and an electronic device. The printed circuit board assembly includes: a printed circuit board, where the printed circuit board includes a functional network, and the functional network is configured to provide an electrical function; a conductive part, where the conductive part is connected to the printed circuit board and is electrically connected in parallel to the functional network; and a cover-shaped structure, where the cover-shaped structure covers the conductive part and is connected to the printed circuit board, and the cover-shaped structure is configured to prevent the conductive part located in the cover-shaped structure from contacting a conductor outside the cover-shaped structure. The foregoing technical solutions can reduce impedance of a circuit board, improve a current utilization, and further improve mechanical reliability of the circuit board.

Abstract: A method includes determining to set a face area as a current focus window when a face is detected in a to-be-photographed image, detecting a preset location in the face area, adjusting a width of the current focus window according to the preset location in the face area, stretching a length of the current focus window according to at least a first preset ratio and a second preset ratio, calculating at least a contrast value of an image in the first focus window and a contrast value of an image in the second focus window, and determining a final focus window according to the at least two contrast values. Therefore, the width of the focus window is reduced, so that such that the focus window is without background content.

Abstract: A charging circuit includes at least two direct current-direct current (DC-DC) conversion circuits coupled between a power supply end and a charging end of the charging circuit. A voltage input end of the DC-DC conversion circuit is coupled to the power supply end, and a voltage output end of the DC-DC conversion circuit is coupled to the charging end. The at least two DC-DC conversion circuits include a first DC-DC conversion circuit and a second DC-DC conversion circuit. The first DC-DC conversion circuit is configured to perform voltage conversion on a voltage at the power supply end, to output a first charging signal to the battery. The second DC-DC conversion circuit is configured to perform voltage conversion on the voltage at the power supply end to output a second charging signal to the battery.
