3M™ Electrically Conductive Adhesive Transfer Tape 9703

3M ECATT 9703 is a pressure sensitive adhesive (PSA) transfer tape with anisotropic electrical conductivity. PSA matrix is filled with silver particles enabling interconnections through adhesive thickness (the Z-axis) between substrates .

Features of  Transfer Tape 9703:-

  • Low outgassing acrylic adhesive
  • Anisotropic Z-axis electrical conductivity
  • PSA tack properties
  • Thermal curing not required
  • Easy to use in assembly operations
  • Can be applied as die-cut parts or in roll form
Applications of Transfer Tape 9703:-
  •  To obtain maximum adhesion, the bonding surfaces must be clean and dry.
  •  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.
  •  To assure electrical resistance stability of 3M ECATT 9703 in any flexible circuit interconnection application, a mechanical clamp or other compressive force should be considered in the design of the application.
