Problems solved by technology

[0003] Using the above method, due to the addition of routing vias on the wiring layer, the routing environment of the RF signal line has changed. Therefore, the problem of impedance discontinuity is likely to occur, and at the same time, capacitive reactance will be introduced, which seriously affects the RF signal line. signal quality

Abstract

The invention discloses a rigid-flex combination board routing structure and a mobile terminal. The rigid-flex combination board routing structure comprises a wiring layer; a signal module and a connecting module, which are disposed on the wiring layer. The rigid-flex combination board routing structure comprises a first shielding cover and a second shielding cover. The first shielding cover is disposed on the signal module in a covered manner, and is provided with a first routing hole. The second shielding cover is disposed on the connecting module, and is provided with a second routing hole in a covered manner. The wire of the signal module is led out from the first routing hole, and is led in the second routing hole, and is electrically connected with the connecting module. The rigid-flex combination board routing structure and the mobile terminal are advantageous in that the first shielding cover is provided with the first routing hole, and the second shielding cover is provided with the second routing hole, and the wire can be led out by using the first routing hole, and is connected with the connecting module by the second routing hole, and therefore the signal transmission between different modules can be realized; and the wire passes through the first routing hole and the second routing hole during the routing process, and therefore the wire passing holes are not required to be arranged in the wiring layer, and therefore the signal transmission quality of the rigid-flex combination board can be guaranteed.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a wiring structure of a soft-hard combination board and a mobile terminal. Background technique [0002] In the wiring of the soft-rigid board, in order to prevent electromagnetic interference between functional modules on the wiring layer, such as adjacent signal modules, shielding covers are usually used to avoid electromagnetic interference on the signal modules. However, since the high-speed radio frequency signal line on the signal module needs to control the impedance of the signal to improve the quality of the signal. Therefore, at present, when the RF signal line is routed, it is usually used to add routing vias on the wiring layer in the shielding cover, and use the routing vias to route to other signal modules, so as to realize the connection of signals between different signal modules . [0003] Using the above method, due to the addition of routing vias on the wiring l...
