Rogers RO4000 series PCB materials are circuit materials designed for high-performance, high-frequency applications. They are commonly used in communication systems, high-reliability and complex multi-layer circuits, and wireless communication equipment. Here are some key parameters and characteristics of Rogers RO4000 series PCB materials:

Dielectric Constant (Dk): 

The RO4003C material in the RO4000 series has a dielectric constant Dk of 3.38 +/- 0.05, which provides tightly controlled dielectric constant and low loss characteristics.

Dielectric Loss (Df): 

RO4003C has a Df value of 0.0027 at 10 GHz, exhibiting low dielectric loss, which is very important for high-frequency signal transmission.

Coefficient of Thermal Expansion (CTE): 

RO4003C material has a Z-axis coefficient of thermal expansion of 46 ppm/°C, which helps maintain dimensional stability in thermal shock applications.

Glass Transition Temperature (Tg): 

RO4000 series materials have a Tg greater than 280°C (536°F), ensuring thermal stability within the circuit processing range.

Processing Compatibility: 

RO4000 series materials are compatible with traditional PCB manufacturing technologies such as FR-4, but at a lower cost.

PCB-36

Flame Retardant Rating: 

RO4003C material is not brominated and therefore cannot meet the UL 94V-0 flame retardant rating standard. For applications requiring a UL 94V-0 flame retardant rating, RO4835™ and RO4350B™ materials are available.

Other Models: 

In addition to RO4003C, the RO4000 series also includes other models such as RO4350B™, which has a UL 94 V-0 flame retardant rating, and other materials with different Dk and Df properties.

Data Sheet: 

Rogers Company provides a data sheet for RO4000 series high-frequency circuit boards, which contains detailed technical specifications and performance data.

Product Series: 

The RO4000 series includes a variety of materials, such as RO4000® LoPro® laminate, RO4360G2™ laminate, RO4400™/RO4400T™ series adhesive sheets, etc., which have different characteristics to meet different design needs.

Copper Foil Options: 

CU4000™ and CU4000 LoPro® copper foils are compatible with RO4000 Series laminates, providing additional design flexibility and performance.

Material Composition: 

The RO4000 Series are glass-reinforced hydrocarbon and ceramic (non-PTFE) laminates designed for performance-sensitive, high-volume commercial applications.

Design Specifications: 

The design specifications for RO4003C are 3.55 dielectric constant and RO4350B is 3.66. These are values at specific frequencies and conditions.

Copper Peel Strength: 

The copper peel strength of RO4003C is 0.88 N/mm (5 plies), while RO4350B is 0.70 N/mm (4 plies), which is a measure of the bonding strength of the material to the copper layer.

Thickness and Size: 

RO4003C and RO4350B are available in various standard thicknesses, such as 0.008 inch, 0.012 inch, 0.016 inch, etc., and different standard panel sizes, such as 12" x 18", 24" x 18", etc.

Environmental Impact: 

Prolonged exposure to oxidizing environments may change the dielectric properties of hydrocarbon-based materials, which changes are faster at higher temperatures and are highly dependent on circuit design.

Product Advantages: 

The advantages of RO4000 series materials include FR-4-compatible manufacturing process, stable dielectric constant, high thermal conductivity, compatibility with lead-free soldering processes, low Z-axis CTE, optimized cost performance, and can reach UL 94 V-0 Options for flame retardant ratings.
