An electrically conductive adhesive is a glue that is primarily used for electronics. The electric conductivity is caused by a component that makes ca. 80% of the total mass of an electrically conductive adhesive. Electrically conductive adhesive transfer tape (ECATT) 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 the ECATT 9703 easy to use in assembly operations. Electrically connects and mechanically bonds medium pitch flexible circuits with other flexible circuits (flex), rigid printed circuit boards (PCB), or LCD screens. It is also electrically conductive and offers good adhesion to common PCB substrates such as copper, gold, FR-4 epoxy, DuPont™ Kapton™ polyimide, and polyester films. Stable electrical performance in any flexible circuit interconnection application may require mechanical reinforcement (clamping). Electrically Conductive Adhesive Transfer Tapes eliminate the need for secondary grounding solutions like screws and fasteners. EMI shielding tape offers design flexibility, improved antenna performance, reduced cross talk and enhanced ESD protection. The adhesive can’t carry significant current but it is very handy for sensing applications where you don’t want to solder the copper tape. We’ve seen such tape used for EMI shielding, working with EL, making capacitive touch pads, ultra-thin wiring needs, etc. An electrically conductive adhesive is a glue that is primarily used for electronics. The electric conductivity is caused by a component that makes ca. 80% of the total mass of an electrically conductive adhesive. This conductive component is suspended in a sticky component that holds the electrically conductive adhesive together. The particles of the conductive component are in contact to each other and in this way make electric current possible.
