3MTMAnisotropic Conductive Film For Touchscreen Applications Enhancing Design Flexibility * Electrically conductive film * Low temperature bonding to most plastic flex circuits * Fast cure time with low pressure * Flex-to-flex or flex-to-board 3M Anisotropic Conductive Film for Touchscreen Applications TM Advanced adhesive technology for today's plastic screens Electronic devices continue to get smaller, lighter, thinner and faster. They also have dramatically increased functions: watch TV, take a picture, listen to music, make a phone call, surf the Web or answer e-mails, all on a single device. The serious challenge for product designers is how to enable the user to access all that functionality with a simple, easy-to-use interface. One solution is the use of touch screens. 3MTM Anisotropic Conductive Films (ACF) enable designers to use new touch-sensitive display materials like ITO-coated PET. These heatbondable, electrically conductive adhesive films consist of a thermoset-thermoplastic adhesive matrix randomly loaded with conductive particles which allow interconnection of circuit lines through the adhesive thickness, but spaced far enough apart to be electrically insulating in the plane of the adhesive. Application of heat and pressure causes the adhesive to flow and to bring the circuit pads into contact by trapping the conductive particles. The low-temperature and low-pressure cure and short bond time of these adhesives make them the ideal choice for the demanding applications of flex-to-board, flex-to-flex and flex-to-ITO-coated plastic.
