What are the Properties of the Shengyi S7439G PCB Material?
The Shengyi S7439G PCB Material has lots of great properties, which has made it useful for different pcb needs. Let’s consider them.
Temperature for glass transition (Tg)
The Tg value for the Shengyi S7439G PCB Material stands at 189 degrees centigrade under the DMA condition. While for the DSC condition, it stands at 181 degrees centigrade.
This value is high. The Tg value describes the temperature at which this material changes from a solid state to something rubber-like. Therefore, when the Shengyi S7439G PCB Material’s Tg goes higher than 189 degrees centigrade, then there is a high risk of fire.
Decomposition Temperature (Td)
The Shengyi S7439G PCB Material has a decomposition temperature of 405 degrees centigrade. This is with the condition of 5% weight loss.
The decomposition temperature of a PCB material decomposes chemically. This temperature is very important whenever you are fabricating a circuit board. Shengyi decomposition temperature is above 320 degrees Celsius. Therefore, the Shengyi S7439G PCB Material has a great decomposition temperature.
The Shengyi S7439G PCB Material has a thermal stress of 100s. This is under the condition of 288 degrees centigrade and a solder dip. With this value, you can be sure that this material will achieve robustness of physical boards, thermal reliability, as well as long life for the multilayer printed circuit boards.
Coefficient of Thermal Expansion
The coefficient of thermal expansion (CTE) of the Shengyi S7439G PCB Material is 45 ppm/℃ before glass transition temperature. The Coefficient of thermal expansion of a PCB material measures how its size changes relating to temperature variations. If the temperature of a material rises beyond its Tg, the CTE will also increase. The Shengyi S7439G PCB Material features a great coefficient of thermal expansion.
Furthermore, the coefficient of thermal expansion (CTE) of the Shengyi S7439G PCB Material is 225 ppm/℃ after the glass transition temperature. Also, the CTE at 50 to 260 degrees stands at 2.5%.
There are several dissipation factors for this material. One at 1GHz, with a value of 0.0043. The other one is at 10GHz at a value of 0.0060, while another, also at 10GHz has a value of 0.0070. This value indicates how the Shengyi S7439G PCB Material will perform in different environments as well as applications.
Furthermore, dissipation factor indicates a material’s inefficiency to act as an insulator or hold energy. From the value above, the Shengyi S7439G PCB Material has a low dissipation factor; therefore its insulator system is more efficient.
The Shengyi S7439G PCB Material has a volume resistivity of 9.0 x 108 MΩ.cm. This value measures the electrical resistance and insulation of the Shengyi S7439G PCB Material. Once this value rises, the circuit will experience a less movement of electric charge.
The Shengyi S7439G PCB Material has a surface resistivity of 2.0 x 107 MΩ. At this value, you can measure the insulation or electrical resistance of the Shengyi S7439G PCB Material. Furthermore, it is affected by temperature and moisture.
