Abstract

The invention discloses a circuit board of a mobile terminal and a mobile terminal having the same. The circuit board comprises a substrate, an element, a solder mask, and a shielding board. A grounded loop line and a to-be-shielded line that is arranged at the inner side of the loop line and is spaced from the loop line are arranged on the bottom surface of the substrate. The element is arranged on the top of the substrate and is connected with the to-be-shielded line electrically. The solder mask is arranged on the bottom of the substrate and covers the to-be-shielded line. The shielding board arranged below the solder mask covers the to-be-shielded line; and the peripheral edge of the shielding board is in contact with the loop line. According to the embodiment of the invention, the circuit board has advantages of good shielding effect, low cost, and low thickness and the like.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to a circuit board of a mobile terminal and a mobile terminal having the circuit board of the mobile terminal. Background technique [0002] The circuit board in a mobile terminal houses the electronics on the top layer and the wiring on the bottom layer, which needs to be shielded to prevent it from being disturbed. The circuit board in the related art shields signals by increasing the number of layers of the circuit board, but increasing the number of layers will not only increase the cost of the circuit board, but also increase the thickness of the circuit board, affecting the control of the thickness of the mobile terminal. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, the present invention proposes a circuit board for a mobi...
