RT/duroid 6006 High Frequency PCB
RT/duroid 6006 high frequency PCBs are ceramic-PTFE composites which are designed for electronic and microwave circuit applications requiring a high dielectric constant.
?
RT/duroid 6006 PCB can provide us with high dielectric constant which is helpful to enable circuit size reduction. With low loss property, it is ideal for operating at X-band or below. Additionally, the tight Dk and thickness control deliver repeatable circuit performance.?
Now let’s look at the data sheet of RT/duroid 6006 laminates.
?
The first one is dielectric constant. It’s available with value of 6.15 at 10GHz with tolerance +/-0.15. The second parameter is dissipation factor. It’s available with a low value of 0.0027 at 10GHz. This is a very low value.
?
The next is thermal coefficient of dielectric constant (TCDk), the value is -410 ppm/℃, we know the absolute value is very high. That is to say RT/duroid 6006 is not suitable for millimeter wave area and the environments that temperature changes a lot.
?
Then Moisture absorption.
Moisture absorption is the total weight of the circuit board material absorbing external water, which is measured in percentage. At higher frequencies the smaller the better, with a typical value of between 0.1% and 0.2%. The water absorption of RT/duroid 6006 performs as low as 0.05%.
?
Thermal conductivity is 0.49 W/m/K. CTE in X and Y axis is good, Z-direction looks like a little bit higher. Decomposition temperature performs good at 500℃ with thermogravimetric analysis. ?
RT/duroid 6006 has a density of 2.7 g/cm3, a specific heat capacity of 0.97 J/g/K and copper peel of 14.3 pli.
Finally, RT/duroid 6006 material is flame resistant with UL94-V0 grade and environmently friendly.
?
For RT/duroid 6006 PCBs, we can provide you with single layer board, double layer board, multi-layer board and hybrid types.
?
RT/duroid 6006 PCBs have wide thickness. These are the standard thickness such as 10 mils, 25 mils, 50 mils and 75mils etc. Finished copper on PCB is 1oz and 2oz.
?
Our maximum PCB size on RT/duroid 6006 laminate 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 and yellow etc is available in house. There’s immersion gold, HASL, immersion silver, immersion tin, bare copper and OSP etc. for pads protection.
?
There is a type of 50mil RT/duroid 6006 PCB with immersion silver for patch antennas. RT/duroid 6006 PCBs can be used in applications of 8 to 40 GHz of telecommunications, aerospace and defence etc.
?We can also see their applications in aircraft collision avoidance systems, ground radar warning systems and satellite communications systems etc.
