Semitron® ESd 520HR has an industry first combination of electrostatic dissipation (ESd), high strength and heat resistance. This new ESd material is ideal for making nests, sockets and contactors for test equipment and other device handling components. The key features of 520HR are its unique ability to resist dielectric breakdown at high voltages (>100V). The graph below demonstrates the electrical performance of plastic materials commonly used in automated test handlers. Typical carbon fiber enhanced products become irreversibly more conductive when exposed to even moderate voltage.
Only Semitron® ESd 520HR maintains its performance throughout the voltage range, while offering the mechanical performance needed to excel in demanding applications.
- Surface resistivity: 1010 - 1012 ohms/sq
Semitron ESd 520HR is part of the Quadrant EPP family of products designed for use in the semiconductor industry, where electrostatic dissipation is a requirement. It is a compression-molded, static dissipative PAI that combines high heat and chemical resistance with incredible dimensional stability. It also offers consistent static dissipation that withstands exposure to higher voltages without dielectric breakdown.
