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. Tape 9703 can be applied as die cut
parts or in roll form and has good adhesion to common EMI/RFI substrates such as
aluminum, stainless steel, and smooth gasket materials.
