Abstract

The invention discloses a printed circuit board (PCB) and a hand-held terminal. A first part and a second part are arranged on a PCB base plate, the first part and the second part are arranged to be adjacent with each other, the first part and the second part are in crimping connected with the PCB base plate, and the first surface of the second part is made of a shielding material, for reducing the interference caused to other parts working in a first frequency range when the first part works in the first frequency range. According to the scheme provided by the invention, through the second part whose first surface is made of the shielding material, signals emitted by the first part are shielded from other wireless network signals in the same frequency range, such that the interference caused to other parts working in the same frequency range when the first part is used is avoided, such as the influence caused to the application of a control system or WIFI and the like, and the first part is enabled to be compatible with other parts in the same frequency range.

Description

technical field [0001] The invention relates to the radio frequency field, in particular to a printed circuit PCB board and a handheld terminal. Background technique [0002] In a handheld terminal, such as a mobile phone, the sub PCB of the mobile phone is usually integrated with a first component, a second component and an antenna, and the antenna is arranged outside the shell of the second component. [0003] The working frequency of the first component is between 0Hz and 5GHz, and the wire network without antenna can only work in this frequency range, which will obviously affect the work of the wireless network. Contents of the invention [0004] In view of this, the present invention provides a printed circuit PCB board and a handheld terminal to solve the problem in the prior art that the connection mode of the first component will affect the work of the wireless network of other components. The specific solutions are as follows: [0005] A printed circuit PCB board...
