Electrically Conductive Acrylic Pad (eCAP) 7805
Product Description
3M™ Electrically Conductive Acrylic Pad (eCAP) represents a breakthrough in electrically conductive PSA tape and
conductive gasket technology. 3M™ Electrically Conductive Acrylic Pad 7805, 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 silver coated fillers which allow 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 7805 is ideal for electrical bonding and ESD grounding of electronic and electrical devices. 3M eCAP 7805 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 7805 also electrically connects and mechanically bond EMI/RFI shield and
gasket to metal frames and enclosures. The low contact resistance and tape construction result in good EMI performance.
Patented Technology
3M™ Electrically Conductive Acrylic Pad 7805 is a self-stick EMI gasket pad or tape which provides good electrical
conductivity for EMI shielding and ESD grounding. Made with a proprietary technology, the pad achieves a unique filler
distribution in three dimensional structure throughout the adhesive matrix. This makes the tape an excellent choice for use
near electronic components and assemblies. The tape is supplied on 50 meter rolls in width 600 mm.
