The present invention relates to a circuit board to which a 3D formed electromagnetic shielding film is attached, a 3D formable electromagnetic shielding film, a 3D formed electromagnetic shielding film, and a method for attaching an electromagnetic shielding film to a circuit board. The circuit board includes an electronic component. The 3D formed electromagnetic shielding film includes a molding layer, a shielding layer, and an adhesive film. The molding layer and the adhesive film are laminated. The shielding layer is a conductive non-woven layer embedded in the adhesive film. A ratio of a surface area Sof the electromagnetic shielding film after forming with an upper surface area of the electronic component deducted to a surface area Sthereof before forming with the upper surface area of the electronic component deducted is 1.5 to 17. The electromagnetic shielding film is attached to the electronic component of a system-in-package module by means of a 3D formation process, and has good electromagnetic shielding performance. The circuit board to which the 3D formed electromagnetic shielding film is attached is suitable for a wave soldering process or a reflow soldering process in a subsequent manufacturing procedure, and the reflow soldering process does not cause any damage to the electromagnetic shielding film.
