3M™ XYZ-Axis Electrically Conductive
Acrylic eCAP Pads 7830N
Product Description
3M™ XYZ-Axis Electrically Conductive Acrylic eCAP Pads 7830N 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 with 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 for initial to final stages of EMC
design for electronic components and assemblies.
Product Features

– Standard thickness of 7830N: 0.2, 0.3, 0.4, 0.5 mm
• Easy application in die-cut or in roll form
• No need for additional process for PSA coating
• Single-sided
• Good XYZ-axis electrical conductivity
• Good shock absorption and damping performance
• Good adhesive and cohesive strength
• Rework – easy removal without adhesive residue
Applications
3M eCAP Pads are a 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 helps provide electrical conductivity 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 Pads can be applied as die cut parts or in roll form and offers excellent cutting
properties in various converting process.
