3M™ ECATT 9704 is a high adhesion pressure sensitive adhesive (PSA) transfer tape with anisotropic electrical conductivity. Filled with silver particles enabling connectivity through adhesive thickness (the Z-axis) between substrates.
Electrically connects and adhesively bonds medium pitch flexible circuits with other flexible circuits (flex), rigid printed circuit boards (PCB) or LCD screens.
Electrically connects and adhesively bonds EMI/RFI shield and gaskets to metal frames and enclosures.
Tape 9704 is designed to have lower typical out gassing residuals as compared to a similar type conductive adhesive product, such as 3M™ Electrically Conductive Adhesive Transfer Tape 9705. Tape 9704 is a more surface aggressive ECATT on many substrates which will allow a higher level of adhesion build as measured via a peel adhesion test method and as compared to the 3M™ Electrically Conductive Adhesive Transfer Tapes 9703 or 9705. As Tape 9704 is a more aggressive ECATT tape, it is generally not compatible with Indium Tin Oxide (ITO) coatings or other easily corroded surfaces.
