Circuit board and mobile terminal

Abstract

The invention provides a circuit board and a mobile terminal. The circuit board comprises a substrate layer, a copper foil layer, a connecting terminal and a covering film, wherein the copper foil layer is stacked on the substrate layer and comprises a circuit zone and a grounding zone placed at one side of the circuit zone; the circuit zone is provided with an electric conduction wiring; the grounding zone is provided with a grounding copper foil which is used for grounding; the connecting terminal is fixed on the circuit zone and electrically connected with the electric conduction wiring; the covering film covers the copper foil layer and is provided with a first window through which the connecting terminal passes and a second window corresponding to the grounding zone; the second window exposes the grounding copper foil so that the ground copper foil can introduce static electricity at the periphery of the connecting terminal to realize grounding, thus improving the quality of the circuit board and enhancing the safety.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a circuit board and a mobile terminal. Background technique [0002] Welding, repairing, and installing the connector on the circuit board require manual operation or robot operation. Usually, maintenance tools or installation jigs need to directly contact the connector on the circuit board and also touch the connection The electronic components around the socket easily generate static electricity around the connection socket or the connection socket, and the static electricity cannot be eliminated by grounding, which affects the connection performance of the connection socket or affects the electronic components and conductive lines around the connection socket, thereby affecting the circuit board Use, prone to safety accidents. Summary of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a circuit board and a mobi...
