摘要： An electronic device includes a camera module comprising a circuit board, a lens, a first IC chip, and at least one metal column. The lens is mounted on the circuit board. The first IC chip and the metal column are arranged on a surface of the circuit board away from the lens. An attachment includes a body and a second IC chip. The first IC chip and the second IC chip can communicate with each other. The circuit board includes a first surface closed to the attachment. The metal column is arranged on the first surface, and the body includes a second surface close to the camera module. The body further includes at least a connecting channel. The metal column is located in the connecting channel to realize the electrical connection between the camera module and the attachment.

摘要： A circuit board assembly in a camera module for blocking unwanted light when images are captured includes a circuit board, a sensor, and an optical blocking body connecting the circuit board and the sensor. The circuit board includes a base board and a photomask. The photomask is arranged on a surface of the base board, the base board includes conductive circuit layers and dielectric layers, the conductive circuit layers and the dielectric layers are alternately arranged, the sensor being electronically connected to the conductive layers. The optical blocking body, the photomask, and the dielectric layers block ambient light entering the camera module other than through the lens assembly of the camera module.
