High Frequency PCB Rogers 20mil 0.508mm RO4350B
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RO4350B hydrocarbon ceramic laminates are designed to offer superior high frequency performance and low cost circuit fabrication. The selection of laminates typically available to designers is significantly reduced once operational frequencies increase to 500 MHz and above. RO4350B material possesses the properties needed by designers of RF microwave circuits and matching networks and controlled impedance transmission lines. Low dielectric loss allows RO4350B material to be used in many applications where higher operating frequencies limit the use of conventional circuit board materials.
For RO4350B PCBs, we can provide you with single sided board, double sided board, multi-layer board and hybrid types. RO4350B PCBs have wide thickness. There are the standard thickness such as 10 mils, 20 mils, 30 mils, 60mils etc. and non-standard thickness such as 4 mils, 6.6 mils,13.3 mils and 16.6 mils etc. Finished copper on PCBs is 1oz and 2oz.
Our maximum PCB size on high frequency materials is 400mm by 500mm, it can be a single board in the sheet and also can different designs in this panel. Solder mask of green, black, red and yellow etc is available in house.
There’s immersion gold, HASL, immersion silver, immersion tin, bare copper etc. for pads plating.
