3M™ Ultra-Thin Double-Coated Tape 55261P is an ultra-slim 30-micron (0.030 mm) industrial tape featuring an ultra-thin polyester carrier and high-shear acrylic adhesive. Engineered for bonding graphite thermal dissipation sheets, copper foils, and flexible printed circuits (FPC) in ultra-slim smartphones and tablet computers.
Key Performance Highlights
- Ultra-thin 0.030 mm (30 µm) thickness minimizes thermal resistance and vertical stack height
- Bonds graphite sheets and copper heat spreaders directly to IC shields with maximum heat transfer
- High shear strength prevents slippage under high-temperature CPU operation
- Available in 50m standard rolls and 200m production rolls for automated roll-to-roll laminating
Recommended Industrial Applications
Graphite heat-dissipation sheet attachment, flexible printed circuit (FPC) bonding, smartphone battery pull-tabs
