This article explores the properties, benefits, manufacturing process, and applications of S1000 2M and why it is an ideal choice for high-temperature PCB applications

High Tg Material S1000-2M

What is S1000 2M?

S1000-2M is a high-Tg FR-4 material that offers excellent thermal resistance, mechanical stability, and electrical properties. It is widely used in multilayer PCBs, especially those subjected to harsh thermal and mechanical stresses. The high glass transition temperature (Tg) of S1000-2M enhances its ability to maintain structural integrity under elevated temperatures, making it ideal for high-performance electronics.

Key Properties of S1000 2M

1. High Glass Transition Temperature (Tg) – Tg ≥ 180°C, ensuring the material remains stable under high heat conditions.
2. Excellent Thermal Stability – Withstand high operating temperatures, reducing the risk of delamination.
3. Low Coefficient of Thermal Expansion (CTE) – Provides dimensional stability, preventing warping under thermal cycling.
4. High Decomposition Temperature (Td) – Ensures the material does not break down under thermal stress.
5. Superior Mechanical Strength – Enhances the durability and reliability of PCBs, especially in multilayer designs.
6. Good Dielectric Properties – Offers high insulation resistance and stable signal transmission, crucial for high-frequency applications.
7. Lead-Free Soldering Compatibility – Supports RoHS-compliant manufacturing processes.
