3MTM Z-Axis Adhesive Film 5303R adheres and provides an interconnection of the flexible printed circuit to the printed circuit board.
Application Description
3M Z-Axis Adhesive Film 5303R represents an alternative to many lead-based interconnections systems such as solder. Electrically connects and mechanically bonds flexible printed circuit--including TAB (Tape Automated Bonding) circuits--to a variety of electronic substrates and metallizations, including printed circuit boards, glass substrates (LCD displays) and flex circuits.

Benefits/Advantages To Customer
Fine pitch interconnection: Bonds to pads as small as 100 mil²; pitch as fine as 5. 5 mils. [. . . ] The adhesive film is supplied on a cleanroom compatible poly release liner for easy handling and is provided via plastic reel. Electrical interconnection is made by contact between conductive particles in the adhesive (0. 5 mil diameter or smaller) and circuit lines on the substrates. During the heat bonding operation (which cures and crosslinks the adhesive), pressure is applied and maintained until the system is cooled. As the temperature declines, the adhesive contracts to a greater degree than the particles. The circuits are pulled together against the particles and held there. Low electrical resistance bonds capable of withstanding most burn-in and thermal cycle tests, including -55º C/125º C (-67ºF/257ºF) thermal cycling or 85º C (185ºF)/85% relative humidity aging for 1000 hours with less than 10 milliohms change in contact resistance. Repairability can be achieved by application of heat to separate the circuits followed by solvent clean-up of the site.
