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 3M ECATT 9703 easy to use in assembly operations.
|Insulation Resistance||3.4 x 1014 ohms/square (estimated based on 3M™ Electrically Conductive Adhesive Transfer Tape 9703)|
