A new liquid crystal polymer (LCP) from Solvay Specialty Polymers, Alpharetta, Ga., is said to meet the rigorous performance demands of new high-speed USB 3.0 surface mount connectors. Specially formulated Xydar MG-850 LCP is said to deliver the high flow, flatness, and dimensional stability required for new 12-gigabyte connectors that target applications in desktop and laptop computers as well as tablets.

            The new grade is a 50% glass/mineral reinforced polymer that reportedly fills thin walls over long flow lengths. The proprietary mineral and glass reinforcement package provides excellent warp resistance, according to Glenn Cupta, global business development manager for electrical/electronics. He says MG-850 offers manufacturers exceptional performance for these next-generation connectors, providing even tighter tolerances and lower warpage compared to the company’s standard LCP material. The material also boasts a heat deflection temperature of 520 F (271 C) and infrared reflow capability up to 500 F (260 C). Its low moisture absorption is said to facilitate improved IR reflow performance.
