20mil Dual Layer PCB


0.6mm TMM3 PCB

Introducing our latest shipment of PCBs based on TMM3: the ultimate solution for high-reliability strip-line and micro-strip applications. The Rogers TMM3 thermoset microwave material combines the best features of ceramic and traditional PTFE microwave circuit laminates, all without the need for specialized production techniques. With TMM3 laminates, you can enjoy the benefits of exceptional performance and reliability while avoiding pad lifting or substrate deformation during wire-bonding.


The TMM3 substrates offer exceptional performance and reliability. With a dielectric constant (Dk) of 3.27 +/- .032 at 10GHz and a dissipation factor as low as .0020 at 10GHz, these PCBs ensure consistent signal performance and excellent signal integrity. They also feature a thermal coefficient of Dk of 37 ppm/°K for stability across temperature variations and a high decomposition temperature (Td) of 425°C TGA for thermal stability. Additionally, the PCBs have a copper-matched coefficient of thermal expansion and a thermal conductivity of 0.7W/mk for enhanced reliability and efficient heat dissipation. Available in a thickness range of .0015 to .500 inches (+/- .0015”), these PCBs provide versatility to meet various design requirements.

1. Mechanical properties resist creep and cold flow, ensuring long-term stability.
2. Resistant to process chemicals, reducing damage during fabrication.
3. No sodium napthanate treatment required prior to electroless plating.
4. Reliable wire-bonding due to the thermoset resin base.


This PCB has specifications supplied to meet diverse needs. It's a 2-layer rigid PCBs with a copper layer thickness of 35 μm on each side. The Rogers TMM3 Core has a thickness of 0.508 mm (20mil), providing structural integrity. These PCBs come in a compact size of 51mm x 25mm (1PCS), with a tolerance of +/- 0.15mm. They offer a minimum Trace/Space of 4/7 mils, allowing for precise circuit design, and a minimum Hole Size of 0.4mm to accommodate various component placements. With a finished board thickness of 0.6mm, a finished Cu weight of 1oz (1.4 mils) on outer layers, and a via plating thickness of 20 μm, these PCBs are optimized for reliable interconnection and optimal conductivity. They feature an immersion gold surface finish, green solder mask on both top and bottom layers, and undergo a 100% electrical test prior to shipment to ensure their quality.
