Brief Introduction |
|
|
Metal-based substrates are innovative composites designed for high-frequency applications. These substrates feature a core of high-frequency materials such as PTFE, sandwiched between specialized layers. On one side, a copper foil layer is applied, while the opposite side is coated with either a copper or aluminum base. This unique structure provides exceptional shielding and heat dissipation capabilities, making it ideal for demanding electronic environments. PCBs manufactured using these advanced materials are known as metal-based high-frequency PCBs.
Wangling offers a comprehensive range of high-frequency materials, including F4BM, F4BME, F4BTM, F4BTME, and F4BTMS. These materials are available with either aluminum or copper bases, catering to diverse application needs. For detailed specifications, please refer to the table below. |
