Description

technical field [0001] The invention relates to the technical field of flexible circuit boards, in particular to a flexible circuit board, a circuit connection structure and mobile equipment. Background technique [0002] At present, mobile devices are developing toward thinner and lighter. In order to make the thickness of the mobile device smaller, the arrangement of various electronic devices in the mobile device must be more and more compact, and it is developing towards the direction of integration. [0003] In existing mobile devices, the bottom of the camera module is smeared with heat-conducting silica gel to dissipate heat, which increases the height of the camera module, generally resulting in an increase in the height of the camera module, protruding from the shell of the mobile device, and affecting user experience. An antenna of an existing mobile device is generally connected to a main board through a shrapnel, and then connected to a main ground on the main bo...
