3M Electrically Conductive Acrylic Pad (eCAP) represents a breakthrough in electrically conductive PSA tape and conductive gasket technology. 3M Electrically Conductive Acrylic Pad 7850, a double-sided tape, consists of a high-performance 3M adhesive loaded with conductive fillers and is ideal for EMI/RFI shield and EMI/RFI gasket to metal surfaces. The PSA matrix is filled with carbon filters that allow thermal and electrical interconnection between substrates through the adhesive thickness (the “Z-axis”) and also provides electrically conducting in the plane of the adhesive (“X-Y Axis”).

3M eCAP 7850 is ideal for electrical and thermal bonding and ESD grounding of electronic and electrical devices. 3M eCAP 7850 can be applied as die-cut parts or in roll form and has good adhesion to common EMI/RFI substrates such as aluminum, stainless steel, and smooth gasket materials. 3M eCAP 7850 also electrically connects and mechanically bond EMI/RFI shield and gasket to metal frames and enclosures. The low contact resistance and tape construction results in good EMI performance.

Features:

  • Higher Thermal Conductivity & Thicker ECATT for gap filling.
  • Isotropic XYZ-axis electrical connectivity.
  • High adhesion acrylic adhesive.
  • Improved conformability.
  • Isotropic XYZ-axis electrical connectivity.
  • Bridges wider gaps.
  • Unique particle design allows better resistance in a thicker product.
  • Works well on softer surfaces such as gold to gold.
  • Higher contact resistance on harder surfaces.
