Electronics & Semiconductor Grade PPA
Electronics & Semiconductor Grade PPA is a high-performance material specifically developed for the electronics, electrical, and semiconductor industries, featuring excellent electrical insulation properties, high CTI (Comparative Tracking Index) values, and superior high-temperature resistance. This material performs exceptionally well in SMT (Surface Mount Technology) reflow soldering processes, withstanding lead-free soldering temperatures above 260°C without deformation or performance degradation. Low moisture absorption and high dimensional accuracy make it an ideal choice for precision electronic connectors and semiconductor packages.
