This material is a high-performance PCB material that offers numerous advantages for high-frequency PCB applications. Its unique properties, such as low dielectric loss, high thermal stability, and excellent electrical properties, make it an ideal choice for high-frequency PCBs.
The advantage of using it in high-frequency PCB applications is its ability to maintain signal integrity, which is crucial. The material has low signal loss and excellent high-frequency performance, allowing for more accurate transmission of signals over long distances.
This rating indicates that Shengyi SF202 has excellent flame-retardant properties and can self-extinguish within 10 seconds of exposure to a vertical flame. The VTM-0 rating also means the material does not drip or produce flaming particles during combustion, minimizing the fire risk.
The UL94-VTM-0 rating makes it a preferred material for applications that require high levels of safety and reliability, such as in the aerospace and medical industries.

Yes, it is a double-sided adhesiveless copper-clad laminate. It is a composite material made by laminating a layer of copper foil onto a substrate, which in the case of SF202, is made of polyimide or polyester.
The absence of an adhesive layer between the copper and substrate allows for a thinner and more uniform copper layer, which can result in improved electrical performance. Being adhesiveless can also simplify the production process and reduce the potential for delamination during use.
Yes, this material is halogen-free. It uses a resin system containing no halogenated compounds known to release toxic fumes when burned.
This material is ideal for applications where safety and environmental concerns are prioritized. In addition to being halogen-free, this complies with other environmental standards, including the European Union’s Restriction of Hazardous Substances (RoHS).
