Camera module

A circuit board assembly comprising:

• a circuit board forming at least one grounding tab thereon;
• a lens module mounted on the circuit board, the lens module comprising a lens barrel, a lens unit received in the lens barrel, an image sensor being arranged at an image side of the lens unit and a lens holder surrounding the lens barrel and the image sensor, the image sensor being electrically connected to the circuit board;
• an electromagnetic interference shielding casing surrounding the lens module and the circuit board;
• and
• at least one electrically conductive sheet extending from a lateral edge of the circuit board and electrically connecting the at least one grounding tab to the electromagnetic interference shielding casing, the at least one electrically conductive sheet comprising a basewall connected to the circuit board and at least one sidewall bending from the basewall, the at least one sidewall extending into a gap defined between the electromagnetic interference shielding casing and the lens holder and electrically connected to the electromagnetic interference shielding casing.
