  • Patent number: 8796826
    Abstract: A device and method for minimizing the forces that may compromise a lead frame mount to a support structure in an integrated circuit die package during various packaging method steps. When a window clamp is used to provide pressure during a lead frame bonding step or during a wire bonding step during packaging, the vertical force applied by the window clamp may be transferred in lateral direction by the physical contour of the top plate of the support structure. By changing the physical contour of the top plate of the support structure, such as by disposing a specific kind of contoured protrusion, one may minimize or eliminate the lateral forces that act against achieving a solid bond of the lead frame to the support structure. Further, during wire bonding, the same minimization or elimination of lateral forces lead to improved wire bonding.

  • Patent number: 8642119
    Abstract: The present disclosure is directed to a camera module that includes at least a semiconducting die, an image-sensing circuit, a lens, a lens aperture, and a coating that adheres to an exterior surface of the camera module. The coating is opaque to light and prevents light from accessing the camera other than through the lens aperture. The opaque coating is applied as a fluid and is cured. In one embodiment, a mask material is selectively applied to exterior surfaces of the semiconducting die, electrical interconnect layers, glass layers, the lens body, or the lens aperture. After applying the opaque coating, the selectively applied mask material is removed. Methods of selectively applying a mask material include applying a conformable and peelably releasable dope-like material, placing an array of joined, selectively shaped rigid masks over an array of assemblies, and applying a conformable mask material that is heat-expandable.

  • Patent number: 8576574
    Abstract: A conductive paint electromagnetic interference (EMI) shield for an electronic module or device. The conductive paint is composed of metal particles suspended in a fluidic carrier. In one embodiment, the conductive paint is sprayed onto exterior surfaces of an electronic module or device from a spray gun. The sprayed conductive paint is cured to remove the fluidic carrier, leaving a metal film coated to the outside of the module or device. In one embodiment used with electronic packages in array form, grooves are cut into an encapsulation material of a module so that the shield protection includes sidewalls of the package. In another embodiment used with camera modules, masking is used to selectively shield portions of the module. In a further embodiment, the shield is electrically connected to a ground conductor of a circuit of the electronic module.
