3M™ XYZ-Axis Electrically Conductive Acrylic Pads (3M eCAPs) represent a
breakthrough in PSA tape and conductive gasket technology. 3M eCAP products are self-stick EMI
gaskets or adhesive transfer tapes which provide good electrical conductive path for EMI shielding
and grounding in electronic devices. Developed under 3M proprietary technology, 3M eCAP
achieves a unique filler distribution in three dimensional structures throughout the adhesive matrix.
This filler distribution in a high performance 3M adhesive makes the tape have good xyz-axis
electrical conductivity and good adhesion performance. 3M eCAP products are an excellent choice
of EMC designers from initial to final stage of EMC design for electronic components and
*emblies.
• Competitive price with low conductive filler content
• No burr
• Various thickness
- Standard thickness of 7830N 0.2, 0.3, 0.4, 0.5 mm
- Standard thickness of 7810 0.15, 0.2, 0.25, 0.3 mm
• Easy application in die-cut or in roll form
• No need additional process for PSA coating
• Single sided or double sided adhesion
• Good XYZ-axis electrical conductivity
• Good shock absorption and damping performance
• Good adhesive and cohesive strength
• Rework - Easy removal without adhesive residue
• Globally Patented Technology
3M™ XYZ-Axis Electrically Conductive Acrylic Pads are combination of established 3M
adhesive technology with state-of-the-art conductive technology. The PSA matrix is filled with
conductive fillers which allow interconnection between substrates through the adhesive thickness
(the “Z-axis”) and also provides electrically conducting and EMI shielding in the plane of the
adhesive (“X-Y Axis”). 3M eCAPs are ideal for EMI/RFI shield and EMI/RFI gasket to metal
surfaces and also electrical bonding and grounding. 3M eCAP can be applied as die cut parts or in
roll form and offers excellent cutting properties in various converting process.
3M eCAP 7830N, a conductive gasket line with single sided adhesion,
consists of a high performance 3M acrylic adhesive loaded with conductive fillers and a conductive
fabric laminate. 3M eCAP 7830 is the * choice for gasket in 0.1 ~ 0.45 mm gap in electronic
components and devices.

3M eCAP 7810, a conductive tape line with double sided adhesion, is
designed to provide an electrical path with adhesively bonding and heat-transfer path between heatgenerating
components and other cooling devices. These tapes offer both good thermal conductivity
and good electrical conductivity. The electrically conductive tape is provided on a silicone treated
polyester release liner for ease of handling and die cutting. The conductive fillers in the product
enhance the physical strength of the tape to improve the re-work and handling.
