Electrically Conductive Tapes and Adhesives 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 3M EMI/RFI shielding and grounding tapes from JBC.

Go-To Materials from 3M

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
