Introduction to IT-180
IT-180ATC is an advanced high Tg (175°C by DSC) multifunctional filled epoxy known for its high thermal reliability and CAF resistance. This material is suitable for a wide range of applications and can withstand 260°C lead-free assembly processes, making it ideal for modern electronic designs.
RO4003C laminates are available in various configurations, using both 1080 and 1674 glass fabric styles, all meeting strict electrical performance specifications. The material is non-brominated and not UL 94 V-0 rated.
