3M™ Electrically Conductive Adhesive Transfer Tape 9705
Product Description
3M™ Electrically Conductive Adhesive Transfer Tape (ECATT) 9705 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
9705 easy to use in assembly operations.
Tape 9705 electrically connects and adhesively bonds medium pitch flexible circuits with other flexible circuits (flex),
rigid printed circuit boards (PCB) or LCD screens. Tape 9705 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 added mechanical reinforcement (clamping or compressing) in the bond area.
Tape 9705 also electrically connects and adhesively bonds EMI/RFI shield and gaskets to metal frames and enclosures. The
low contact resistance and tape construction result in good EMI performance. Tape 9705 can be applied as die cut parts or in
roll form and has good adhesion to common EMI/RFI substrates such as copper, stainless steel, and smooth gasket materials.
