RO4350B High Frequency PCB
|
|
|
|
|
|
Introduction |
|
|
Rogers RO4350B laminates are a proprietary blend of woven glass reinforced hydrocarbon/ceramics that offer electrical performance comparable to PTFE/woven glass and the manufacturability advantages of epoxy/glass. |

Features |
|
|
One of the key features of RO4350B is their low dielectric constant of 3.48 at 10 GHz. A low dielectric constant is desirable in high-frequency applications as it aids in minimizing signal loss and improving signal integrity. |
|
|
|
|
|
RO4350B exhibits a dissipation factor of 0.0037 at 10 GHz. A low dissipation factor is crucial for minimizing signal loss and maintaining high signal quality in high-frequency circuits. |
|
|
|
|
|
Another advantage of RO4350B is?its excellent dimensional stability. It has a low Z-axis coefficient of thermal expansion at 32 ppm/°C. The expansion coefficient is similar to that of copper, which make the board's dimensions remain consistent even under varying temperature conditions. |
|
|
|
|
|
RO4350B materials also have a high glass transition temperature (Tg) of over 280°C (536°F). The high Tg ensures that the PCB retains its structural integrity and dimensional stability even during the elevated temperatures experienced during the circuit assembly process. |

PCB Capability |
|
|
For RO4350B PCBs, we can offer single-sided, double-sided, multi-layer, and hybrid boards. |
|
|
|
|
|
The available thicknesses include standard options like 10 mils, 20 mils, 30 mils, and 60 mils, as well as non-standard thicknesses like 4 mils, 6.6 mils, 13.3 mils, and 16.6 mils. |
|
|
|
|
|
The finished copper on the PCBs can be either 1oz or 2oz. |
|
|
|
|
|
The maximum PCB size we can provide is 400mm by 500mm. |
|
|
|
|
|
Additionally, we offer a range of solder mask colors, including green, black, red, and yellow etc. |
|
|
|
|
|
For pads plating, we offer various options of bare copper, HASL, immersion gold, immersion silver, immersion tin, OSP, ENEPIG, pure gold and so on. |
