What is The Shengyi S1150G Laminate?
Shengyi S1150G laminate is a halogen-free, high-reliability laminate that balances thermal performance with environmental sustainability. It is engineered for high-density, lead-free compatible applications and offers strong reliability in harsh conditions.
Specifically, the TD value of Shengyi laminate is 355°C, and its TG value is approximately 155°C. Based on this TG value, S1150G is classified into the Mid-TG category. If an application demands a laminate with a higher TG value than that of S1150G, then S1150G laminate may not be the most suitable choice for such an application.
Not only is Shengyi S1150G free from halogen, but it also contains no toxic substances or hazardous residues. Moreover, this laminate is renowned for its lead – free property, mechanical process compatibility, and outstanding thermal resistance. As a result, it meets the requirements of RoHS compliance and other environment – related certifications.
The laminate can be applied in a wide range of applications and different types of boards. Here, we present some of the boards that are compatible with this laminate, including lead – free and halogen – free smartphone, Xbox, automotive, and laptop circuit boards.

Features of The Shengyi S1150G Laminate
Glass Transition Temperature (Tg)
The laminate features a glass transition temperature of 155 degree Celsius. Therefore, this PCB material will be unstable once it works beyond 155 degrees Celsius. This Tg value helps to determine the limit of temperature operation.
Dielectric Constant (Dk)
With a dielectric constant (4.5 @1GHz), the Dielectric Constant (Dk) of Shengyi material is a measure of its ability to store electrical energy in a capacitor-like manner. The material maintains a stable dielectric constant, which is essential for high quality pcb boards.
Dissipation Factor (Df)
With a dissipation factor (0.011 @1GHz) translates to reduced dielectric loss, ensuring minimal heat generation during signal transmission, which is crucial for applications that require efficient performance in thermally challenging environments.
Anti-CAF Capability
One of the standout features of Shengyi laminate is its advanced anti-CAF formulation, which significantly reduces the risk of internal failures due to moisture absorption and electrochemical migration—ensuring long term reliability even in harsh environments.
