Introducing the Wangling TP PCB, a revolutionary high-frequency thermoplastic circuit board designed to meet the demanding needs of modern electronic applications. Utilizing a unique composite of ceramics and polyphenylene oxide resin (PPO), the TP material offers exceptional dielectric performance while eliminating the need for fiberglass reinforcement. This innovative design allows for precise adjustments to the dielectric constant, making it an ideal choice for a wide range of applications, including GPS antennas, missile-borne systems, fuzes, and miniaturized antennas.
Key Features
The Wangling TP PCB boasts a versatile dielectric constant that can be tailored from 3 to 25, depending on circuit requirements. This flexibility enables engineers to achieve stable performance across various applications, with common dielectric constants including 3.0, 4.4, 6.0, 6.15, 9.2, 9.6, 10.2, 11, 16, and 20. Notably, the dielectric loss remains low, with minimal variation even at frequencies up to 10 GHz, ensuring reliable signal integrity.
Designed for extreme environments, the TP material exhibits a long-term operating temperature range from -100°C to +150°C. While it excels in low-temperature resistance, care must be taken at temperatures exceeding 180°C, as deformation and copper foil peeling may occur, potentially affecting electrical performance.
Available in a minimum thickness of 0.5 mm, the Wangling TP PCB can be customized in various thicknesses to suit specific design needs. It is also resistant to radiation and features low outgassing properties, making it ideal for aerospace and defense applications. The adhesion between the copper foil and dielectric is more reliable than traditional ceramic substrates with vacuum coating, enhancing overall durability.
