3M 7010333907 Electrically Conductive Tape 0.25in X 36yd

Product Description

The 3M 7010333907 is an electrically conductive Z-axis tape designed for precise, low-resistance electrical interconnection in shielded assemblies. Built on a sensitive acrylic adhesive system, this tape conducts current through its Z-axis only, making it suitable for bonding conductive traces without creating lateral shorts. It ships on a 58-pound polycoated kraft paper liner and is supplied in a 0.25-inch-wide by 36-yard roll. The adhesive is rated for medium-temperature service with high solvent resistance, and it performs on both high-surface-energy (HSE) and low-surface-energy (LSE) substrates. Electrical technicians and electronics assembly professionals use this product in applications requiring stable, repeatable conductivity.

This tape is used for grounded EMI and RFI shielding attachment and for the interconnection of silver ink and polyester-based flexible circuits. It is well suited to electronics manufacturing environments where reliable electrical contact must be maintained across bonded interfaces at moderately elevated temperatures. Typical installations include flex circuit terminations, board-level shielding gaskets, and grounding connections in enclosures where mechanical fasteners are impractical. The tape's stable electrical performance at moderate heat makes it appropriate for assemblies subject to thermal cycling in industrial and commercial electronics.

Key Features

• Z-axis conductivity isolates current flow perpendicular to the tape surface, preventing lateral shorting
• Sensitive acrylic adhesive bonds to both HSE and LSE substrates
• High solvent resistance maintains bond and conductivity in chemically active environments
• Stable electrical performance at moderately high temperatures suits thermal-cycling applications
• 58-pound polycoated kraft paper liner for clean, controlled unwind and application
• 0.25-inch width targets fine-pitch flex circuit and shielding attachment work

Compatibility

Designed for use in grounded EMI and RFI shielding attachment and interconnection of silver ink and polyester-based flexible circuits. Consult 3M product documentation to confirm suitability for specific substrate materials and operating temperature ranges.

Installation Notes

Application should be performed by qualified electronics assembly or electrical technicians familiar with electrostatic-sensitive components and cleanroom or ESD-controlled environments. Surfaces must be clean, dry, and free of oils or contaminants before tape application to ensure full adhesive contact and reliable conductivity. Avoid stretching the tape during application, as dimensional changes can affect Z-axis alignment on fine-pitch circuits. Follow all applicable facility safety procedures and equipment manufacturer guidelines when working inside energized enclosures.
