Hi everyone,

Welcome back to our channel.Today we’re talking about high frequency PCB built on RO3006 material.

Rogers RO3006 printed circuit boards are ceramic-filled PTFE composites designed to offer exceptional electrical and mechanical stability at competitive price, intended for use in commercial microwave and RF applications

Now let’s take a look at the data sheet to learn more the properties of RO3006.

Firstly, RO3006 has a dielectric constant of 6.15 +/-.15. The high dielectric constant enable designers to design the circuit board smaller. So we can miniaturize our circuit size using RO3006. The DK is stable over a wide range of temperatures, so this eliminates the step change in Dk that occurs for PTFE glass materials near room temperature.

The next issue would be the dissipation factor. It’s a very low loss, 0.002 dissipation factor when it’s tested in 10 GHz. And that’s very low loss which helps power amplifier for high gain.

The third one we need to mention is the thermal conductivity. RO3006 material is very good for thermal conductivity. It’s got a number of 0.79 W/m-K, that’s considered very high for thermal conductivity and that does really help thermal management issue for power amplifiers.

Lastly, the coefficient of thermal expansion (CTE). Ideally that should be at 17 ppm/℃because that’s the value of CTE of copper. As you can see the coefficient of thermal expansion of RO3006 on X and Y axis is 17 ppm/℃ which is matched to copper and Z-axis is as low as 24 ppm/℃. This allows for more reliable surface mounted assemblies, it’s ideal for applications sensitive to temperature change. That’s considered pretty good for the plated through holes reliability and excellent dimensional stability.

For RO3006 PCBs, we can provide you with single layer board, double layer board, multi-layer board and hybrid types. RO3006 PCBs have wide thickness. These are the standard thickness such as 5 mils, 10 mils, 20 mils, 25 mils and 50mils etc.

Finished copper on PCB can be 1oz, 2oz and 3oz. Our maximum PCB size on high frequency materials is 400mm by 500mm, it can be a single board in the sheet and also can be different designs in this panel.

Solder mask of green, black, blue, red and yellow etc is available in house. There’s immersion gold, HASL, immersion silver, immersion tin, bare copper etc. for pads surface finish.

We can see its typical applications in GPS antennas, power amplifiers and antennas, patch antennas for wireless communications and direct broadcast satellite etc.

RO3006 PCB also has very low water absorption at 0.02%. The manufacturing process is similar to standard PTFE PCB, so we can get volume manufacturing process and economical pricing to win the market.
