RO4350B LoPro High Frequency PCB 10.7mil Rogers Reverse Treated Foil Circuit Board With Immersion Gold

(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)


Product Description

RO4350B LoPro laminates utilize proprietary technology from Rogers that enables reverse treated foil to bond effectively with standard RO4350B dielectric. This results in a laminate characterized by low conductor loss, enhancing insertion loss and signal integrity while retaining all the desirable attributes of the standard RO4350B laminate system.



Features and Benefits

RO4350B materials consist of reinforced hydrocarbon/ceramic laminates featuring very low profile reverse treated foil, offering several advantages:

Lower Insertion Loss:Enhances signal transmission efficiency.
Low Passive Intermodulation (PIM):Improves overall performance in RF applications.
Increased Signal Integrity:Ensures clearer and more reliable signal transmission.
High Circuit Density:Supports complex circuit designs without compromising performance.


Thermal and Design Characteristics

Low Z-axis Coefficient of Thermal Expansion:Facilitates multi-layer board capability and design flexibility.
Lead-Free Process Compatible:Supports high-temperature processing and complies with environmental regulations.
CAF Resistant:Enhances reliability in challenging environments.


Typical Applications

1.Digital applications such as servers, routers, and high-speed backplanes
2.Cellular base station antennas and power amplifiers
3.LNBs for direct broadcast satellites
4.RF Identification Tags
