 High Frequency PCB Made on RO4350B | Rogers RO4350B RF PCB

Hi,

Good day. Hope this email finds you well.

 

RO4350B PCBs are hydrocarbon ceramic boards which are designed to offer superior high frequency performance and low cost circuit fabrication. We benefit from its low dielectric tolerance and low loss, stable electrical properties, low thermal coefficient of dielectric constant, low Z-axis expansion and low in-plane expansion coefficient.

 

Our PCB Capability (RO4350B)

PCB Material:	Glass reinforced hydrocarbon ceramic laminates
Designator:	Rogers RO4350B
Dielectric constant:	3.48  ±0.05 (process)
	3.65 (design)
Layer count:	1 Layer, 2 Layer, Multilayer, Hybrid type (Mixed)
Copper weight:	0.5oz (17 µm), 1oz (35µm), 2oz (70µm)
Laminate thickness:	10mil (0.254mm), 20mil (0.508mm), 30mil (0.762mm), 60mil (1.524mm)
PCB size:	≤400mm X 500mm
Solder mask:	Green, Black, Blue, Yellow, Red etc.
Surface finish:	Bare copper, HASL, ENIG, Immersion Silver, Immersion tin,  OSP,etc.

 

Hybrid PCB

In order to save production cost but not reduce signal loss in high frequency environment, combining with FR-4 came into being. The high frequency material is used in signal layer and FR-4 glass fiber material is used in other layers.

 

We are able to provide you with prototype, small batches and mass production service. If you are interested in RO4350B high frequency PCB, please feel free to write back with your requirement, we are willing to share our price with you.

 

Best regards
