Material suppliers are enhancing and developing new materials to help manufacturers produce eco–friendly system components. A key element is the elimination of hazardous chemicals and substances to comply with regulations such as the European Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) directives. Removal of lead from E/E components has forced manufacturers to move to lead–free soldering processes which require temperatures usually above 260°C. This presentation will focus on (LCP) Liquid Crystal Polymer and PPS (Polyphenylene Sulfide) as these engineering polymers can withstand these higher temperatures and maintain extremely tight dimensional tolerances, both during the molding process and in the soldering phase. Also discussed will be the effect that Non–governmental organizations such as Greenpeace are having on consumer electronic OEMs regarding the restrictions and use of certain brominated flame retardants in their products. Both LCP and PPS are rated V–0 per UL94 and are inherently flame resistant without additives. More and more companies realize being "green" is good, and are increasing the use of these high–temperature polymers in their products.
