Abstract:
Disclosed is an EMI shielding material. The EMI shielding material includes a resin material and metal particles mixed with each other, and the surface of the metal particles has an insulating protective layer. Further disclosed is a communication module product, including a module element arranged on a substrate, and the periphery of the module element that requires EMI shielding is filled with said shielding material. Further disclosed is an EMI shielding process, including the following steps: a. preparing a communication module on which a module element is provided; and b. applying said shielding material to a region of the module element that needs to be EMI shielded on the communication module. The shielding material shields a chip region in a wrapping manner, that is, the shielding material wraps and shields all six surfaces or six directions of the chip, and provides shielding between chips.
