3. Introduction to I-Tera MT40

I-Tera MT40 is a high-performance laminate specifically designed for modern high-speed digital and RF/microwave PCB designs. It boasts excellent thermal and electrical performance, making it a cost-effective alternative to PTFE and other high-end microwave laminates.

With a glass transition temperature (Tg) of 215°C and decomposition temperature (Td) of 360°C, it offers superior thermal stability, suitable for high-temperature manufacturing processes and harsh application environments. Its dielectric constant (Dk) of 3.45 and dissipation factor (Df) of 0.0031 ensure minimal signal loss, even at frequencies up to W-band. Unlike PTFE-based materials, I-Tera MT40 does not require special through-hole treatments, simplifying manufacturing and reducing costs. Available in both laminate and prepreg forms, it provides a complete material solution for multilayer, hybrid, and double-sided PCBs.

6. What is Single-Ended Impedance Control?

Single-ended impedance control refers to the process of designing PCB traces to maintain a specific impedance (50 ohm inthisproduct) between a single signal trace and its reference plane. It is critical for high-speed signal transmission, as impedance mismatches can cause signal reflection, distortion, and loss.thistop layer uses 5 mil traces to achieve 50 ohm single-ended impedance, ensuring stable signal integrity and minimizing interference in high-frequency applications.

7. Why Edge Plating?

Edge plating (metalized board edges) is essential forthis PCB for three key reasons: First, it enhances mechanical strength, preventing edge damage during assembly and use. Second, it improves electrical performance by providing a continuous ground path, reducing electromagnetic interference (EMI) and crosstalk. Third, it facilitates reliable soldering and grounding when the PCB is mounted in enclosures, ensuring consistent connectivity and stability in harsh operating environments.

This product meets international industry standards, with strict quality control and optimized design to deliver consistent, reliable performance for high-end electronic applications. It perfectly balances performance, cost, and manufacturability, making it an ideal choice for engineers and enterprises pursuing high-quality PCB solutions.
