Abstract
An EMI shield for a camera module subassembly includes a first conductive portion covering an optical unit and a top surface of a circuit substrate of the camera module subassembly and a second conductive portion covering a bottom surface of the circuit substrate, such that the two portions are in contact. The EMI shield can also include an extension to cover a flexible circuit substrate and its connector, as well as can include an EMI attenuator over an aperture formed in the first conductive portion above the optical unit. The EMI shield of the invention provides improved EMI shielding and EM compatibility at the camera module packaging level, especially for frequencies in the megahertz and gigahertz range, by shielding substantially all of the camera module subassembly.
