Thermally Conductive

Adhesive Transfer Tapes 8805,
8810, 8815, 8820

Typically done manually.  Die cut parts , pre-spaced on a release liner are used
for application on the heat sink by a component supplier.

High temperature adhesion and thermal conductivity.

Grease, liquid conductive adhesives, phase change materials and solutions that
use mechanical fasteners such as clips and screws.

High mechanical strength: 3M

™

Tapes work well in high temperature

environments, helping to keep heat sinks where they are supposed to be.

Excellent shock performance: Elastomeric properties of adhesive provides
excellent shock performance.

High dielectric strength: High dielectric strength provides electrical isolation

Improved surface wetout: 3M Tapes provide increased wetout of the adhesive
on the heat sink, lowering thermal impedence.

Improved productivity: Tapes bond with light pressure and have immediate
tack, avoiding the mess, hassle and cost of grease and clips.  Tapes also
eliminate long cure times and fixturing required of liquid adhesives.

Available as die-cut parts: Tape may be die-cut into custom shapes and sizes
by a converter and pre-applied to one surface for later bonding.

Pure adhesive film construction: No carrier, that would hinder gap filling, is
needed.  This results in fewer material interfaces (a leading cause of poor
thermal performance).
