This disclosure relates to a camera module and an electronic device. The camera module includes: a first decorative member having an accommodating space for accommodating a first lens group of the camera module; wherein the first decorative member has a grounded conductive portion; a second decorative member disposed on the first decorative member and having a light-transmitting area aligned with the opening of the accommodating space; the second lens group of the camera module covering the light-transmitting area; and conductive adhesive disposed between the first decorative member and the second decorative member, and electrically connected to the conductive portion and the second decorative member respectively. By providing conductive adhesive and grounding it, embodiments of this disclosure can reduce electrostatic interference generated by the electrical portion of the second decorative member on the camera module, and also achieve connection stability between the first and second decorative members.

This invention relates to the field of aluminum foil production technology, specifically a method for treating aluminum powder on the surface of rolled aluminum foil. This method effectively removes aluminum powder adhering to the aluminum foil surface by combining physical and chemical treatments, improving the purity and safety of the aluminum foil. It is applicable to industries such as electronics, electrical appliances, and food packaging. The treatment effect of aluminum powder can be further optimized by controlling static electricity elimination during the rolling process, selecting the cleaning solution, and using controlled atmosphere heat treatment conditions. Furthermore, the introduction of quality inspection ensures that there is no residual aluminum powder on the surface of the treated aluminum foil, improving product reliability and safety. This invention provides a new solution for quality control in the aluminum foil production process.
