Introducing a newly shipped PCB based on TMM6 material. TMM6, the Rogers TMM 6 thermoset microwave material, is a cutting-edge ceramic thermoset polymer composite designed to provide reliability and performance for high plated thru-hole strip-line and micro-strip applications. Offering the advantages of both ceramic and traditional PTFE microwave circuit laminates, TMM6 eliminates the need for specialized production techniques typically associated with these materials. With a unique dielectric constant (Dk) compared to other materials in its product family, TMM6 sets a new standard in microwave PCB technology.
Key Features:
- Dielectric constant (Dk) of 6.0 +/- .08 at 10GHz ensures precise signal propagation.
- Dissipation factor of .0023 at 10GHz minimizes signal loss for optimal performance.
- Thermal coefficient of Dk of -11 ppm/°K provides exceptional thermal stability.
- Coefficient of thermal expansion matched to copper for reliable operation.
- Decomposition Temperature (Td) of 425 °C TGA ensures high-temperature resilience.
- Thermal Conductivity of 0.72W/mk enables efficient heat dissipation.
- Available in a thickness range of .0015 to .500 inches, offering versatility in design.
Benefits:
The TMM6 PCB offers a range of benefits that enhance its reliability and functionality:
- Mechanical properties resist creep and cold flow, ensuring long-term durability.
- Resistant to process chemicals, reducing damage during fabrication.
- Based on a thermoset resin, allowing for reliable wire-bonding.
- Compatible with all common PCB processes, making it versatile and easy to work with.

PCB Stackup and Construction Details:
This PCB features a 2-layer rigid PCB stackup, providing simplicity and versatility. The construction details are as follows:
- Copper_layer_1: 35 μm for efficient signal conduction.
- Rogers TMM6 Core: 0.635 mm (25mil) for optimal electrical properties.
- Copper_layer_2: 35 μm for consistent signal performance.
With a board size of 56.04mm x 53.18mm, each PCB is manufactured with a tight tolerance of +/- 0.15mm, ensuring consistent dimensions. The minimum trace/space capability of 4/4 mils allows for intricate circuit designs and efficient routing. The minimum hole size of 0.3mm provides versatility for component placement. The absence of blind vias simplifies the manufacturing process while maintaining structural integrity.
The finished board thickness of 0.7mm strikes a balance between durability and compactness. The outer layers feature a 1oz (1.4 mils) copper weight, ensuring excellent conductivity and signal integrity. With a via plating thickness of 20 μm, reliable electrical connections are established throughout the PCB. The surface finish of immersion silver enhances conductivity and protects against oxidation. While there is no top or bottom silkscreen or solder mask, this allows for a clean and unobstructed PCB surface.
To ensure the highest quality, each PCB undergoes a 100% electrical test before shipment, guaranteeing that it meets rigorous performance standards. With these outstanding specifications, the TMM6 Thermoset Microwave PCB is ready to empower your electronic designs with reliability, precision, and efficient signal transmission.
