Isola IS410

IS410 is a high-performance FR-4 epoxy laminate and prepreg system designed to support the printed circuit board industry’s requirements for higher levels of reliability and the trend to use lead-free solder. Isola’s IS410 has a glass transition temperature (Tg) of 180C and is specially formulated for superior performance through multiple thermal excursions., passing 6x solder tests at 288C. IS410 is optimized for enhanced drilling performance allowing high aspect ratio holes of <= 10 mils. Its unique resin chemistry provides CAF resistance with the benefit of long term reliability of boards built wth small feature designs.
