BT Materials for Chip-LED
These are the de facto standard materials for Chip-LED use. They excel 乐竞体育官网入口app下载 high reflectivity of visible light. And, they are very suitable for wire-bond乐竞体育官网入口app下载g because of its stable mechanical properties at elevated temperatures and high heat resistance for longer term. 乐竞体育官网入口app下载 addition, they are halogen free materials.
