Pressure-Sensitive Adhesives Electrically Conductive Tapes For EMI/RFI Shielding & Grounding
Today’s design trends in electronics feature complicated antenna structures, higher frequencies, and smaller grounding areas – creating new challenges for engineers tasked with shielding against electromagnetic (EMI) and radio frequency interference (RFI). To complicate matters, EMI/RFI applications often have unknown issues come up in the prototyping phase and the design no longer meets Electromagnetic Compatibility (EMC) standards. A quick fix is needed. And fast.
Enter custom die-cut parts made by JBC featuring 3M EMI/RFI shielding and grounding tapes.
3M™ Electrically Conductive Adhesive Tapes - Go-To Materials
3M offers a robust line of Electrically Conductive Tapes & Films designed specifically for use in EMI shielding and grounding applications. Not only do they minimize EMI noise and crosstalk, but they also provide EMI protection from a wide range of frequencies, adhere well to a variety of substrates, and can be die-cut to the custom size and shape needed for your application.
Technical Applications For Die-Cut EMI/ RFI Shielding Tapes Include:
- Electrostatic discharge (ESD)
- Shield-can lid
- PCB/Flex/Chassis grounding
- Bond line gap shielding
- EMI shield and gasket attachment
- Electrical connectivity to medium pitch flexible circuits and PCBs
- Flex circuit to flex circuit interconnection
- Passive intermodulation (PIM) management
