Abstract: An apparatus configured to measure electromagnetic radiation coupled from an image sensor integrated circuit (IC) to a nearby cell phone antenna has an image sensor PCB with the image sensor IC on a first side and image sensor decoupling capacitors disposed on a second side, the image sensor PCB disposed within a shielding box. The apparatus also has an image processor PCB with an image processor IC on a first side and at least one image processor decoupling capacitors, the image processor IC electrically coupled to the image sensor IC. The image processor IC is located outside the shielding box, and the at least one image processor decoupling capacitor is within the shielding box. In embodiments, the decoupling capacitors are shielded with separate, additional, metal covers.

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.
