3M™ Anisotropic Conductive Film (ACF) 7376-10 is an electrically conductive, heat-bondable adhesive film. The unbonded film is sticky at room temperature and is made of a thermoset-elastomer and thermoplastic adhesive matrix packed with conductive particles. These particles allow interconnection of circuits through the adhesive but are distanced apart for the product to be electrically insulating. Heat and pressure cause the adhesive to flow and to bring the circuit pads into electrical contact by pinning the conductive particles. The adhesive cross-links quickly at modest bonding temperature and pressure. The 3M ACF 7376-10 is used in bonding a flexible printed circuit to another flexible printed circuit or flexible printed circuit to polyester-based devices or a flexible printed circuit to camera module devices.
