3M 7000048975 Electrically Conductive Tape 12in X 108yd

Product Description

The 3M 7000048975 is a pressure-sensitive adhesive (PSA) transfer tape engineered for anisotropic electrical conductivity through the Z-axis only. It conducts through the adhesive thickness but not across the plane of the tape, making it well suited for grounded EMI/RFI shielding attachment and interconnection of silver ink and polyester-based flexible circuits. The permanently tacky PSA matrix contains aligned conductive particles that deliver stable electrical performance at moderately high temperatures. No thermal bonding is required for application. The tape is also repositionable and reworkable, which simplifies alignment during assembly. Licensed electricians and electronics assembly technicians are the primary installers.

This tape is used in applications where controlled Z-axis conductivity is required, including attachment of flex circuits to FR-4 boards, grounding of EMI/RFI shielding layers, and interconnection tasks in electronics manufacturing and field service environments. Compatible substrates include polyimide and polyester flex circuit materials, FR-4 board, copper, steel, and aluminum. It is appropriate for both light industrial and commercial electronics assembly scenarios where a clean, repositionable bond is needed without the heat exposure of a thermal bonding process.

Key Features

• Anisotropic conductivity through the Z-axis only — no lateral conduction across the tape plane
• Repositionable and reworkable PSA system — no thermal bonding required
• Stable electrical performance at moderately high temperatures
• Adheres to polyimide, polyester, FR-4, copper, steel, and aluminum surfaces
• Suitable for grounded EMI/RFI shielding attachment and flex circuit interconnection
• Transfer tape format simplifies application in tight or precision assembly areas

Compatibility

Designed for use with silver ink and polyester-based flexible circuits, polyimide flex circuit materials, FR-4 board, copper, steel, and aluminum substrates. Suitable for grounded EMI/RFI shielding attachment and flex circuit interconnection applications.

Installation Notes

This tape is typically applied by electronics assembly technicians or licensed electricians working on shielding and flex circuit interconnection tasks. Ensure all surfaces are clean, dry, and free of oils or contaminants before application. Because the tape is repositionable, take care to align it precisely before applying final pressure to achieve a consistent bond. No heat source or bonding press is required.
