M6 High Speed PCB Low Loss Multilayer 2mm Impedance Circuit Board

We are pleased to introduce a high speed PCB with Megtron 6 (M6)laminates,which is specifically engineered for applications in 5G communication, millimeter-wave radar, high-speed servers, and high-performance computing (HPC). With its exceptional electrical and thermal properties, the M6 laminate ensures superior performance in high-frequency signal transmission, making it an ideal choice for advanced electronic devices.

Key Features of Megtron 6 (M6)
The M6 laminate stands out in the market due to its unique combination of properties, making it a preferred material for high-frequency and high-speed applications. Here are some of its standout features:

1. Low Dielectric Loss (Df):

Dissipation Factor: 0.002 at 1GHz/23°C, 0.0037 at 13GHz

Ensures minimal signal loss, making it ideal for high-frequency applications.

2. Stable Dielectric Constant (Dk):

Dk: 3.4 at 1GHz/23°C, 3.34 at 13GHz

Provides consistent signal transmission across a wide frequency range.

3. Excellent Thermal Reliability:

High Tg value: >185°C (DSC method), 210°C (DMA method)

Thermal Decomposition Temperature (Td): 410°C (TGA method)

Ensures stability under high-temperature conditions, making it suitable for demanding environments.

4. Low CTE (Coefficient of Thermal Expansion):

X/Y axis: 16 ppm/°C, Z axis: 45 ppm/°C

Reduces the risk of warping or delamination during thermal cycling.

5. Compatibility with FR-4 Processing:

No special equipment required, reducing production costs and simplifying manufacturing.

6. RoHS and Halogen-Free Compliance:

Meets global environmental standards for green manufacturing.

7. Flammability Rating: UL 94V-0

Ensures safety and reliability in high-temperature and high-stress environments.
