What are the differences between different Rogers board models in PCB?

High frequency boards produced by Rogers Corporation are widely used in the PCB industry, mainly because of their excellent electrical properties, especially in high-frequency applications. Based on the information collected, the following are the differences between several Rogers plate models:

RO4000 Series: 

This series of plates is known for its low loss characteristics and FR-4-like processing technology. They are commonly used in designs in the microwave and millimeter wave bands and have stable dielectric constant (Dk) and low dissipation factor (Df). RO4000 series materials have a coefficient of thermal expansion (CTE) similar to copper, helping to provide excellent dimensional stability.

RO4003C™: 

RO4003C is a glass cloth-reinforced, ceramic-filled hydrocarbon composite material that has the electrical properties of PTFE/glass cloth and the processability of epoxy resin/glass. It has strict process control, stable dielectric constant and loss characteristics, and the cost is much lower than traditional microwave laminates.

RO4350B™: 

RO4350B material is a glass cloth reinforced, ceramic/hydrocarbon composite material with low dielectric constant and low loss characteristics. It is processed the same as standard epoxy/glass, requires no special through-hole processing, is lower cost, and achieves a UL 94 V-0 flame retardant rating.

RO4835™: 

Offering excellent high temperature stability and oxidation resistance, RO4835 laminate is a low-loss material suitable for applications with low insertion loss requirements. It is available with Rogers' proprietary LoPro® reverse-treated copper foil and is RoHS compliant and UL 94 V-0 flame retardant.

RO4835IND™ LoPro®: 

This material is suitable for 60-81 GHz short-range industrial radar applications, providing low loss and stable RF performance. It has excellent dielectric constant uniformity and low insertion loss.

RO4835T™: 

RO4835T is an extremely low-loss material used for the inner circuit core boards of multilayer boards (MLB). It has high performance properties and can be processed using standard FR-4 processes.

RO4360G2™: 

RO4360G2 laminate is a material with extremely low loss properties that provides a good balance between performance and processability, and is a high dielectric constant (Dk) thermoset laminate.

RO4500™: 

The RO4500 series of high frequency laminates are cost-effective and designed to meet the needs of the antenna market and are fully compatible with traditional FR-4 processing and high-temperature lead-free soldering processes.

RO4700™: 

The RO4700 series antenna-grade laminate is a highly reliable, high-performance, low-cost product that can replace traditional PTFE laminates and can be plated through holes without special processing.

RO3003™ Series: 

Rogers' PTFE composites containing special ceramic fillers for commercial microwave and RF applications. This series provides a variety of different dielectric constant (Dk) values while maintaining consistent mechanical properties, suitable for multilayer board designs with different single layers.

RO4000® LoPro® Laminate: 

Proprietary technology allows the inversion of copper foil to be matched to standard RO4000 series materials, reducing conductor loss and improving insertion loss and signal integrity.

RO4360G2™ Laminate: 

It is the first high dielectric constant (Dk) thermosetting laminate. The processing process is similar to FR-4. It has extremely low loss characteristics and can improve the processing performance of multi-layer board structures.

RO4830™ Laminate: 

Ideal for price-sensitive millimeter wave applications such as 76-81 GHz automotive radar sensors. It can be manufactured using standard FR-4 processes and has extremely low insertion loss and high reliability.

RO4835™ Laminate: 

has excellent stability under high temperature conditions and significant oxidation resistance, suitable for applications requiring low insertion loss, enabling low-cost circuit manufacturing.

RO4835IND™ LoPro® Laminate: 

Provides low loss and stable RF performance with excellent dielectric constant uniformity for 60 to 81 GHz short-range industrial radar applications.

RO4835T™ Laminate: 

As a supplement to RO4835™ laminate, when the design and processing of multilayer boards (MLB) require thinner laminates, it can be used as the inner circuit core board of the multilayer board.

RO4700™ Antenna-grade Laminate: 

It is a highly reliable, high-performance, low-cost product that can replace traditional PTFE laminates and can be plated through holes without special processing.

RO3000 Series: 

This is a PTFE (polytetrafluoroethylene) composite material offered by Rogers, specifically designed for commercial microwave and RF applications. They are available in a variety of different dielectric constant (Dk) values, maintaining a stable dielectric coefficient over a wide temperature range.

RO4000 Series: 

In addition to the previously mentioned RO4003C and RO4350B, the RO4000 series also includes other materials, which are characterized by low loss and excellent high-frequency performance, and are suitable for applications such as satellite TV LNB, microstrip lines, and cellular base station antennas.

RO5000 Series: 

It is also a PTFE composite material with low dielectric constant (Dk) and low loss, which is very suitable for high frequency/broadband applications. They maintain consistent electrical characteristics over a wide frequency range and are easy to form.

RO4500™ Laminates: 

This family of materials is designed for the antenna market and is cost-effective. They are compatible with traditional FR-4 processing and high-temperature lead-free soldering processes without the special processing required by traditional PTFE materials.

RO4700™ Antenna-Grade Laminates: 

This series provides reliable, high-performance materials that can be used as a replacement for traditional PTFE laminates. They are also compatible with FR-4 and high temperature lead-free soldering processes.

RO4835™ Laminate: 

This material offers excellent high temperature stability and oxidation resistance, making it suitable for applications requiring low insertion loss.

RO4835IND™ LoPro® Laminate: 

Suitable for 60-81 GHz short-range industrial radar applications, providing stable RF performance and low loss.

RO4835T™ Laminate: 

Inner circuit core board for multi-layer board designs with the properties of a high-performance material at an affordable price.

RO4360G2™ Laminate: 

A high dielectric constant (Dk) thermoset laminate with extremely low loss characteristics and similar processing technology to FR-4.

The common advantages of these materials include process compatibility similar to FR-4 materials, low loss characteristics, stable electrical properties, and good thermal properties. Different models of Rogers plates cover different dielectric constant ranges from low to high, as well as different levels of loss factors to meet the needs of different high frequency applications.

When selecting the correct Rogers high frequency board, design engineers need to consider the circuit's operating frequency, required electrical performance, cost budget, processing technology compatibility, and compliance with environmental regulations. Each material has its own unique properties and is suitable for specific application scenarios.
