Product description

3M Thermally Conductive Tape is a double-sided tape using a ceramic-filled acrylic adhesive that provides both heat transfer and a mechanical bond between components and heat sinks. It replaces clips, screws and thermal grease all at once, enabling thinner, more compact designs and a clean, fast assembly process with no cure time.

Typical Applications

Bonding aluminum heat sinks to chips, memory and chipsets on circuit boards
Bonding LED strips to aluminum bars in tube and panel lights
Securing backlights and display LED modules to metal frames
Heat transfer between batteries, circuit boards and housings in handheld devices
Bonding thermal sensors and small power components to equipment housings

Advantages

Conducts heat and bonds at the same time, with no clips or screws needed
Clean, fast application with no curing and no overflow like liquid adhesives
Electrically insulating, safe to apply close to printed circuits
Easy to die-cut to part shape, suitable for automated assembly

Key Specifications

Property	Value
Thermal conductivity	0.6–1.0 W/m·K

Application Notes

Surfaces must be flat, clean and free of oil and grease; wipe with isopropyl alcohol and allow to dry. Press or roll down evenly at about 100–200 kPa for a few seconds to eliminate air bubbles, since air voids sharply increase thermal resistance. The tape is suited to small gaps and flat surfaces; for warped surfaces or large gaps, choose a soft thermal gap pad instead.

Choose the thinnest tape that still compensates for surface flatness, since thermal resistance increases almost in direct proportion to adhesive thickness.

Contact the technical team at AMS Vietnam for advice on thickness, die-cutting to your drawings and samples for thermal testing.
