Dive into the details below to discover the key features and benefits of the TMM4 20mil PCB.


Unmatched Material Composition:

The TMM4 high frequency PCB is built with Rogers TMM4 hydrocarbon ceramic thermoset polymer composites, ensuring superior performance and durability.


Precision Stackup:

Our TMM4 20mil PCB features a 2-layer rigid construction, providing a robust foundation for your electronic designs. The copper layers, each measuring 35 μm, ensure efficient current conduction and allow for high-density circuit designs. The TMM4 0.508 mm substrate offers excellent stability and insulation properties, contributing to the overall reliability and performance of the PCB.



Superior Construction Details:

The TMM4 20mil material PCB boasts precise construction details that cater to your specific needs. With board dimensions of 94mm x 90mm, accurate to within +/- 0.15mm, this PCB offers ample space for your components and circuits. The minimum trace/space of 5/5 mils allows for intricate designs and ensures optimal signal integrity. With a minimum hole size of 0.4mm and no blind vias, the PCB simplifies assembly and enhances reliability. The finished board thickness of 0.63mm, 1oz finished copper weight on outer layers, and a via plating thickness of 20 μm reinforce the PCB's durability and electrical performance.


Reliable Finish and Testing:

To ensure the highest quality standards, the TMM4 20mil PCB undergoes rigorous testing. It features an immersion gold surface finish, providing excellent solderability and corrosion resistance. Moreover, the PCB is subjected to a 100% electrical test prior to shipment, guaranteeing optimal functionality and reliability.


Comprehensive Statistics:

With a total of 57 components and 112 pads, the TMM4 20mil PCB offers versatility and flexibility for your electronic designs. It features 76 thru-hole pads, 31 top SMT pads, and 5 bottom SMT pads, accommodating various component types and connections. With 96 vias and 7 nets, you have the freedom to create complex circuitry and achieve desired functionalities.


Dielectric Constant: Precision and Consistency

The TMM4 PCB boasts a dielectric constant (εProcess) of 4.5±0.045 at 10 GHz, with an impressively tight tolerance. This indicates the exceptional precision and consistency of the PCB's performance across various frequencies. When designing high-frequency circuits, having a stable dielectric constant is crucial to minimize signal loss and ensure reliable signal transmission.


Dissipation Factor: Low Loss, High Efficiency

With a dissipation factor of only 0.002 at 10 GHz, the TMM4 20mil PCB exhibits an exceptionally low loss characteristic. This low dissipation factor allows for efficient energy transfer and helps maintain signal integrity, ensuring optimal performance of your electronic designs.


Thermal Coefficient of Dielectric Constant: Stability in Any Environment

The TMM4 PCB offers a thermal coefficient of dielectric constant (TCDK) of +15 ppm/°C from -55°C to +125°C. This low TCDK value indicates exceptional stability of the dielectric constant across a wide temperature range. This stability ensures that the dielectric constant remains consistent, even in challenging environmental conditions, resulting in reliable performance and accurate signal transmission.
