Isotropically conductive adhesives for electronic manufacture of flexible printed circuit boards

The use of polyester as flexible printed circuit board substrates implies t hat alternative low temperature curing conductive materials are required fo r assembling electronic circuits. In addition, conductive adhesives are use d as a solution which eliminates the environmental problems encountered wit h solder materials. The combination of Polymer thick film (PTF) technology on polyester films and the use of isotropic conductive adhesives as joining material provide a cost effective and environmental friendly manufacture m ethod. Polymer materials comply with recycling concepts.
