3M(TM) Z-Axis Electrically Conductive Tape 9703, 1 in x 36 yd, 9 per case Bulk Pressure sensitive adhesive (PSA) transfer tape with anisotropic electrical conductivity through the Z-axis. Designed for grounded EMI/RFI shielding attachment or interconnection of silver ink/polyester based flexible circuits. Provides stable electrical performance at moderately high temperatures and good adhesion to metallic and other commonly used surfaces, including polyimide and polyester flex circuit materials, FR-4 board, copper, steel, aluminum and more. It is a permanently tacky system consisting of a PSA matrix with aligned conductive particles. These particles allow electrical conduction through the adhesive thickness ("Z-axis"), but not in the plane of the tape. The PSA properties of tape 9703 make it easy to handle and apply without need for thermal bonding. Tape 9703 is also repositionable and reworkable.
