What Is a BT Epoxy PCB? A BT Epoxy PCB is a high-performance PCB built using BT epoxy resin (Bismaleimide-Triazine), a material widely used in IC substrate and semiconductor packaging applications. Compared to standard FR-4, a BT Epoxy PCB offers: Higher glass transition temperature (Tg) Lower dielectric loss Better dimensional stability Improved reliability under thermal...
