摘要： Embodiments of this application disclose a packaging assembly and an electronic device. The packaging assembly includes: a substrate and a chip, where the substrate includes a first surface and a second surface that are opposite to each other, the first surface of the substrate is opposite to a surface of the chip, a plurality of electrodes are disposed on the first surface of the substrate, a signal transmission port is disposed on the second surface of the substrate, and the signal transmission port is electrically connected to the electrode; and a plurality of pads are disposed on the surface of the chip opposite to the substrate, and the pads are soldered and connected to the electrodes through a plurality of conductive connection portions, where one pad is connected to the plurality of conductive connection portions, and the plurality of conductive connection portions are electrically connected to one signal transmission port. Therefore, the plurality of conductive connection portions are disposed on a single pad, so that stress may be evenly distributed to the plurality of conductive connection portions. This improves reliability of a component. In addition, the plurality of conductive connection portions connected to one pad back up each other's performance. This provides a plurality of performance guarantees, and improves electrical connection stability.

摘要： This application provides a filter, a remote radio unit, and a base station. The filter includes a filter body, a connector, and a lightning protection structure. A dielectric body is disposed inside the filter body. A signal can be transmitted in the dielectric body. The filter body is provided with a through hole, and the through hole runs through the dielectric body. A portion of an inner conductor of the connector is located at one end of the through hole. The signal can be transmitted between the connector and the filter body. At least a portion of the lightning protection structure is located at the other end of the through hole. The lightning protection structure is grounded and is electrically connected to the inner conductor. The through hole is used to accommodate a portion of the inner conductor, or the through hole is used to accommodate portions of the inner conductor and the lightning protection structure. The disposed lightning protection structure can improve lightning protection performance of the filter, and prevent the filter from being damaged due to breakdown, to ensure normal operation of the filter, the remote radio unit, and the base station.
