Abstract: A waterproof electronic device includes a shell, a first electronic module, a second electronic module, and a flexible printed circuit FPC. A first compartment and a second compartment which are in communication with each other through a through hole are formed in the shell. The through hole is used for the FPC to pass through. The first and second electronic module are arranged in the first and second compartment respectively. The first electronic module is coupled to the second electronic module by the FPC which passes through the through hole. An opening in communication with the through hole is provided on the shell. A magnetic colloidal structure is arranged in the through hole, where the magnetic colloidal structure seals the through hole.

Abstract: A flexible circuit board, a circuit board assembly, and an electronic device are provided. The flexible circuit board includes at least a flexible dielectric layer and a first connection metal layer. The flexible dielectric layer includes a through hole extending along a thickness direction of the flexible dielectric layer. The through hole includes a middle basic hole and outer auxiliary holes. Two or more outer auxiliary holes are distributed and arranged along a circumferential direction of the middle basic hole. The middle basic hole is in communication with the two or more outer auxiliary holes. The first connection metal layer is arranged on an inner wall of the through hole and is connected to the flexible dielectric layer. The first connection metal layer includes a middle channel extending along a thickness direction.
