3M™ Anisotropic Conductive Film (ACF) 7371-30 is heat bondable, electrically conductive adhesive film. The unbonded film is slightly tacky at room temperature and consists of a thermoset-elastomer and thermoplastic adhesive matrix randomly loaded with conductive particles. These particles allow interconnection of circuit lines through the adhesive thickness but are spaced far enough apart for the product to be electrically insulating in the plane of the adhesive. The application of heat and pressure causes the adhesive to flow and bring the circuit pads into contact by trapping the conductive particles. The adhesive rapidly cross-links at modest bonding temperature and pressure. 3M ACF 7371-30 may be used to bond a flexible printed circuit to another flexible printed circuit or to a plastic touch screen or plastic flat panel display device.
