  • Best Practices for 3M Electrically Conductive Adhesive Transfer Tape 9703

    *See Terms of Use Below

    1. Surface Preparation

      To obtain maximum adhesion, the bonding surfaces must be clean and dry.

    2. Application

      Pressure must be applied to the bond line after assembly to wet the substrates with 3M™ Electrically Conductive Adhesive Transfer Tape (ECATT) 9703 and to engage the conductive particles with the substrates to make electrical connection. Mechanical pressure (roller, metal bar) or finger pressure at 15 psi (0.10 Mpa) or greater is suggested. Heat may be applied simultaneously to improve wetting and final bond strength.

      3M ECATT 9703 should be applied between 60°F - 158°F (15°C - 70°C). Tape application below 50°F (10°C) is not recommended because the adhesive will be too firm to wet the surface of the substrate, resulting in low adhesion.

      Adhesion builds with time, up to 24 hours may be required to reach final adhesion values.

      Temperature Performance: The electrical performance of 3M™ Electrically Conductive Adhesive Transfer Tape (ECATT) 9703 is more sensitive to temperature than the peel performance. 3M ECATT 9703 is not recommended for high or low temperature excursions where the electrical performance might be compromised, even if holding power is not affected. The user is responsible for the temperature performance qualification of 3M ECATT 9703 in their design. Contact your 3M Technical Service Representative for further information about the temperature performance of 3M ECATT 9703.

    3. Removal

      Mechanically separate the parts using torque for rigid parts and peel for flexible ones. Remove the adhesive by rubbing it off with a Scotch-Brite® Hand Pad, clean up the site and apply new adhesive. The force needed to separate the parts and/or remove the adhesive can be reduced by softening the adhesive by heating 158°F - 212°F (70°C - 100°C) or using solvents.

      Note: When using solvents, be sure to follow the manufacturer’s precautions and directions for use when handling such materials.
