3M 7000048869 Electrically Conductive Tape 3.0 Mil 4 in X 108 Yd

Product Description

The 3M 7000048869 is an XYZ-axis electrically conductive tape designed for EMI and RFI shielding in demanding electronic assembly and manufacturing applications. It uses a pressure-sensitive acrylic adhesive that bonds in all three axes, providing reliable electrical conductivity through the thickness, length, and width of the tape. The tape measures 3.0 mil thick with a 4.0 mil polycoated kraft paper liner and ships in a 4-inch-wide by 108-yard roll. It is rated for medium temperature resistance and high solvent resistance, making it suitable for environments where chemical exposure is a concern. Electronics technicians, EMI shielding specialists, and PCB assembly professionals are the primary installers.

This tape is suited for use in electronics manufacturing, PCB assembly, flex circuit bonding, and component-level shielding applications where grounding or shielding continuity must be maintained across a joint. It performs on both high surface energy (HSE) and low surface energy (LSE) substrates, broadening its use across plastic housings, metal enclosures, and laminated surfaces. Applications include shielding cables, connectors, and board-level components in consumer electronics, telecommunications equipment, and industrial control panels.

Key Features

• XYZ-axis conductivity provides electrical continuity through all three dimensions of the bond
• Pressure-sensitive acrylic adhesive bonds to both high and low surface energy substrates
• 3.0 mil tape thickness with a 4.0 mil polycoated kraft paper liner for clean, consistent dispensing
• Medium temperature resistance and high solvent resistance for use in chemically active environments
• Designed for EMI and RFI shielding in high-productivity production settings
• Available in a continuous 108-yard roll format to minimize splices and changeovers

Compatibility

Designed as an OEM-style conductive tape for EMI and RFI shielding applications in electronic assemblies, flex circuits, and grounded enclosures where XYZ-axis conductivity is required.

Installation Notes

Installation is performed by electronics technicians or EMI shielding specialists in assembly or field-service environments. The bonding surface should be clean, dry, and free of oils or particulate before tape application. Apply firm, even pressure across the full tape surface to achieve full adhesive contact and consistent conductivity. Consult applicable IPC standards and the assembly design specification before selecting this tape for a safety-critical or high-voltage shielding application.
