A printed circuit board, a method for manufacturing a printed circuit board, and a mobile terminal

Abstract

The invention provides a printed circuit board, a method for manufacturing the printed circuit board, and a mobile terminal. The printed circuit board includes a PCB board body, and a groove is arranged on the first surface of the PCB board body; a PCB device, and the PCB device includes A connection terminal, a part of the PCB device is located in the groove, the connection terminal includes a first part located in the groove and a second part located outside the groove, and the first part is electrically connected to the conductive layer in the PCB board body. The above structure can reduce the height of the device protruding from the surface of the PCB board body, thereby reducing the height of the assembled structure formed after the printed circuit board and the electronic device are assembled, and can also increase the distance between the device body and the shield body under the premise of the same height. The safety gap improves the ability of the assembly structure to resist external static pressure. At the same time, the PCB device is electrically connected to at least two conductive layers in the PCB body, which can reduce the setting of vias, thereby reducing the impedance and loss caused by vias.

Description

Technical field [0001] The invention relates to the technical field of electronic products, in particular to a printed circuit board, a manufacturing method of the printed circuit board and a mobile terminal. Background technique [0002] Thinning is a current development direction of mobile terminals. However, with the diversification of functions implemented by mobile terminals and the continuous improvement of equipment performance requirements, more and more power management modules will be used in the development of mobile terminals. For example, the charging circuit, the power supply network of the main chip, the driving circuit of the display screen and so on. In these power management modules, most of them have adopted a switching power supply implementation. In a switching power supply, the size of the components that need to be used are relatively large, such as power inductors. [0003] At the same time, due to the switching noise of the switching power supply, the po...
