Key Features
- Halogen-free, antimony-free, red-phosphorous-free for full environmental compliance
- High-Tg 170C (DSC) / 180C (DMA) with exceptional Td 390C
- T260 and T288 both >60 min for extreme reflow durability
- Anti-CAF capability for fine-pitch HDI reliability
- Lower Z-axis CTE (2.3%) than standard high-Tg materials
Applications
Shengyi S1170G is proven in production for: server and data center boards, automotive ECU modules requiring halogen-free, high-layer networking equipment, 5G base station digital boards, medical diagnostic equipment.
How It Compares
S1170G is the halogen-free upgrade to S1000-2. It achieves V-0 without halogens and delivers higher Td (390C vs 355C). Compared to S1150G (Tg 150C), S1170G offers 20-30C higher Tg. Against Isola 370HR, S1170G is the halogen-free alternative with comparable performance at lower cost.
