AI Overview
), and excellent solderability for fine-pitch components.
Key Features & Advantages
- Substrate (PTFE): Teflon (PTFE) provides a very low dielectric constant () and low dielectric loss, minimizing signal energy loss.
- Surface Finish (ENIG): Provides a flat,, solderable, corrosion-resistant surface (nickel + gold) ideal for BGA and complex components.
- High Performance: Suited for demanding environments, offering thermal stability and high-frequency stability (up to millimeter-wave).
- Applications: Widely used in 5G/6G communication, radar, aerospace, and high-frequency, high-speed designs.
Fabrication Considerations
- Cost: Higher expense due to complex processing and raw material costs.
- Difficulty: PTFE is soft and flexible, requiring specialized drilling, routing, and fabrication techniques to prevent deformation or misalignment.
- Quality Control: Strict monitoring of nickel and gold thickness is essential to ensure solderability.
