Technical Data April 2011 3M Electrically Conductive Adhesive Transfer Tape 9703 Product Description 3M Electrically Conductive Adhesive Transfer Tape 9703 is a pressure sensitive adhesive PSA transfer tape with anisotropic electrical conductivity. The PSA matrix is filled with conductive particles which allow interconnection between substrates through the adhesive thickness the “Z-axis” but are spaced far enough apart for the product to be electrically insulating in the plane of the adhesive. The PSA tack properties and lack of any thermal curing make tape 9703 easy to use in assembly operations. Tape 9703 electrically connects and mechanically bonds medium pitch flexible circuits with other flexible circuits flex , rigid printed circuit boards PCB or LCD screens. Electrically conductive tape 9703 offers good adhesion to common PCB substrates such as copper, gold, FR-4 epoxy, Kapton polyimide and polyester films. Stable electrical performance in any flexible circuit interconnection application may require mechanical reinforcement clamping . Tape 9703 also electrically connects and mechanically bonds EMI/RFI shield and gaskets to metal frames and enclosures. The low contact resistance and tape construction result in good EMI performance.
