3M™ Electrically Conductive Single-Sided Tape 3304BC-S is a single-sided conductive black foil tape that consists of a conductive black copper foil carrier and a patented* conductive non-woven carrier-based acrylic adhesive. The unique design of 3M tape 3304BC-S provides XYZ-based conductivity for contact with small grounding areas but also enhances the physical properties of the tape for workability. 3M tape 3304BC-S provides electrical grounding performance and performance for small-size contacts.
3M tape 3304BC-S is an upgraded version of 3M™ Electrically Conductive Single-Sided Tape 3304BC with an improved surface scratch-resistant black copper foil and continues to use the same high-performance conductive adhesive design with an optimized release liner design.
FEATURES:
- XYZ-axis conductive through the adhesive
- Scratch-resistant black copper foil
- Conformability and edge conformance
- EMI/ESD Shielding performance
- Overlap resistance and electrical contact in small areas
- Handling and workability
APPLICATIONS:
3M tape 3304BC-S is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to the foil backing and needs good electrical conductivity through the top of the foil backing. Common uses include grounding and EMI shielding in equipment, components, and shielded rooms.
