TMM4: The High-Performance Thermoset Microwave Material


Are you in need of a reliable and versatile material for your high-frequency applications? Look no further than Rogers TMM4, a thermoset microwave material designed to deliver exceptional performance in strip-line and micro-strip applications, ensuring high plated-thru-hole reliability.


TMM4 combines the best of both worlds, offering the mechanical and chemical properties of ceramics and traditional PTFE laminates, all without requiring specialized production techniques. This makes it a cost-effective and practical choice for a wide range of applications.


Let's take a closer look at the features and benefits that set TMM4 apart:

Impressive Properties:

  • Dielectric Constant (Dk): With a Dk of 4.50 +/- .045, TMM4 ensures precise signal propagation and impedance control, ensuring optimal performance in high-frequency circuits.
  • Low Dissipation Factor: TMM4 boasts a dissipation factor of only .0020 at 10GHz, minimizing signal loss and maximizing efficiency.
  • Thermal Stability: With a thermal coefficient of Dk of 15ppm/°K, TMM4 remains stable even under challenging temperature variations, providing reliable performance in demanding environments.
  • Thermal Expansion Matched to Copper: The coefficient of thermal expansion (CTE) of TMM4 is carefully matched to copper, reducing the risk of delamination or stress-related issues.
  • High Decomposition Temperature: TMM4 can withstand temperatures up to 425°C (TGA), ensuring its reliability in demanding applications.
  • Excellent Thermal Conductivity: With a thermal conductivity of 0.7 W/mk, TMM4 offers efficient heat dissipation, preventing thermal issues in high-power applications.
  • Low Moisture Absorption: TMM4 exhibits moisture absorption of 0.07%-0.18%, ensuring stability and reliability in humid environments.


Versatile Construction:

TMM4 is available in a thickness range of .0015 to .500 inches (+/- .0015”), allowing you to select the ideal thickness for your specific application needs. Its compatibility with common PWB processes makes it easy to integrate TMM4 into your existing manufacturing workflows.


Reliable PCB Stackup:

For a 2-layer rigid PCB, TMM4 is an excellent choice as the core material. With a thickness of 0.635 mm (25mil), it provides the necessary stability and electrical performance for your circuit design. Copper layers of 35 μm on either side ensure efficient signal transmission.


Comprehensive PCB Construction Details:

The TMM4-based PCB boasts a finished board thickness of 0.8mm, with a 1oz (1.4 mils) outer layer copper weight. The minimum trace/space is 6/8 mils, and the minimum hole size is 0.35mm. Via plating thickness is 20 μm, and the surface finish is immersion gold. The top solder mask is green, while the top silkscreen is white. The PCB undergoes 100% electrical testing before shipment, ensuring its quality and reliability.


Applications and Beyond:

TMM4 finds its application across a wide range of industries and technologies. Some typical applications include RF and microwave circuitry, power amplifiers and combiners, filters and couplers, satellite communication systems, Global Positioning Systems antennas, patch antennas, dielectric polarizers and lenses, as well as chip testers.


Accepted Standards and Availability:

The TMM4-based PCB adheres to the IPC-Class-2 standard, ensuring its quality and reliability. It is readily available worldwide, making it easily accessible for your manufacturing needs.


In conclusion, Rogers TMM4 offers a reliable, versatile, and cost-effective solution for high-frequency applications. Its exceptional dielectric properties, thermal stability, and compatibility with common manufacturing processes make it a top choice for a wide range of industries. Experience the benefits of TMM4 and take your designs to new heights of performance and reliability.
