发明名称 Electromagnetic interference shielding on semiconductor devices
摘要 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.
