3M™ Electrically Conductive Adhesive Transfer Tape 9709S is a pressure sensitive adhesive (PSA) transfer tape with isotropic electrical conductivity. The PSA matrix is filled with conductive fillers which allow interconnection between substrates through the adhesive thickness (the “Z-axis”) and also provides electrical conductivity in the plane of the adhesive (“X-Y Axis”). The PSA tack and adhesion properties allow for room temperature application and assembly processes.
FEATURES
- Tape 9709S has inherent EMI shielding capability.
- Tape 9709S provides an electrical connection and adhesively bonds EMI/RFI shields and gaskets to metal frames and enclosures.
- Can be applied as die cut parts or in roll form.
- Offers good XYZ electrical conductivity performance with good adhesion.
- Can offer lower contact resistance to “hard surfaces” or surfaces with oxide layers.
APPLICATONS
- To obtain maximum adhesion, the bonding surfaces must be clean and dry.
- Pressure must be applied to the bond line after assembly to wet the substrates with 3M™ XYZ/Electrically Conductive Adhesive Transfer Tape 9709S and to engage the conductive particles with the substrates to make electrical connection.
