What is the Mid-Tg S1151G pcb material?
Shengyi S1151G is based on a mid-glass transition temperature (Tg) FR4.0 resin system, that TG is 155°C and providing a balanced thermal performance.The moderate Tg ensures stability and durability in environments where moderate to high temperatures are present. Its stability under temperature variations makes it a reliable choice for applications that experience consistent thermal cycling or are exposed to elevated temperatures during operation. The laminate has a CTI≥600 value, that CTI measures how the insulating material of the circuit board can withstand unintended current to transmit between traces on the PCB.S1151G laminate is a high-quality, versatile PCB material designed for applications that demand excellent thermal reliability, mechanical strength, and environmental sustainability.
The PCB material has a dissipation factor of 0.011 at 1GHz, this value is considered low, the dissipation factor of a material specifies the ability of a material to act as an insulating material. Also, a low dissipation factor indicates low power loss. The Td of S1151G laminate is 380 degrees Celsius at 5% weight loss.The decomposition temperature of a PCB material decomposes chemically. The decomposition temperature is very crucial when fabricating a circuit board. The CTE of laminate is 220 ppm/℃ before glass transition temperature.The CTE of a PCB material measures how its size changes in relation to temperature variations. Moreover, the laminate is compatible with lead-free soldering processes, making it suitable for modern, environmentally-conscious manufacturing environments that adhere to industry standards for lead-free products.Suggested for multilayer <8L and <2oz with through hole construction.

The features of the Mid-Tg S1151G PCB material
Glass Transition Temperature (Tg)
Shengyi S1151G 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 (4.6 @1GHz), the Dielectric Constant (Dk) of Shengyi S1151G 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.
Lead-Free Compatibility
The S1151G laminate is compatible with lead-free soldering processes, making it suitable for modern, environmentally-conscious manufacturing environments that adhere to industry standards for lead-free products. Fully compatible with lead-free soldering processes, aligning with RoHS compliance and promoting environmentally friendly manufacturing practices.
The S1151G material has a CTI≥600, this property is very significant. This is because it offers a quantitative metric by which different materials can be compared. CTI measures the extent at which a PCB material can withstand the unwanted flow of current between traces on the circuit board.
