At NEDC, we are a 3M converter. For that reason, we see a lot of different types of tapes that we can die-cut into custom shapes. When it comes to EMI/RFI Shielding Tapes, there are EMI/RFI Shielding Fabric Tapes, and EMI Shielding Metal Foil Tapes. In this blog, we will discuss the EMI/RFI Metal Foil Tapes. There are a few different tapes here that can be used for different applications due to their construction.
There are a few different constructions below that each have applications:
-Embossed W/ Non-Conductive Adhesive- Electrical Contact through Adhesive
-Non Embossed/Smooth Electrically Conductive Adhesive with Foil- Electrical Contact through Adhesive
-Non Embossed/Smooth W/ Non-Conductive Adhesive – No Electrical Contact through Adhesive
The embossed and electrically conductive adhesive tapes can provide electrical contact through the surface of the substrate, and then through the tape. The non-embossed with non-conductive adhesive is primarily used for grounding, outer wrap for coils, and electrostatic shielding.
Types of Tapes:
-Tin Plated Copper Foil Tapes
-Aluminum Foil Tapes
