Electrically Conductive Acrylic Pad
eCAP 7810
Product Description:
3M™ XYZ-Axis Electrically Conductive Acrylic Pad(eCAP) represents a breakthrough
in PSA tape and conductive gasket technology. eCAP 7810 conducts electricity through
the thickness (Z-axis) and in the plane of the adhesive (X, Y planes) and is ideal for
EMI/RFI shield and EMI/RFI gasket to metal surfaces. eCAP 7810, a double sided tape,
consists of a high performance 3M adhesive loaded with conductive fillers. XYZ-Axis
Electrically Conductive Pad 7810 is ideal for EMI shielding to electronic and electrical
devices. eCAP 7810 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. eCAP 7810 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 XYZ-Axis Electrically Conductive Acrylic Pad is a self-stick EMI gasket pad 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.
