GORE-SHIELD® GS8000 EMI Gaskets

GORE-SHIELD® GS8000 EMI Gaskets

GORE-SHIELD® GS8000 EMI Gaskets are ideal for applications that require conformability, excellent cavity-to-cavity EMI shielding, and superior conductivity at low compressive forces. They are supplied as precision die-cut parts on rolls for high volume assembly. This material is ideal for the cellular phone, PDA, and mobile electronics markets.


GORE-SHIELD® GS8000 EMI Gaskets consist of a nickel-plated conductive polyurethane foam, a conductive pressure sensitive adhesive, a copper foil, another conductive pressure sensitive layer, and a PET carrier film.

Features and Benefits:

  • Low DC resistance and high shielding effectiveness
  • Excellent reliability through Accelerated Life Testing (ALT)
  • Conformable and highly compressible with low force
  • Increases functional space by reducing fixing points
  • Minimizes stress on housing and circuit boards

Applications

EMI shielding for mobile phones, wireless PDAs, or other portable electronic devices.
