What is the difference between RO4003 & FR4 Material?

Typical ro4003 and PCBs differ significantly in one key respect. What this concern is how they are put to use. Ordinary printed circuit boards can only be used within a certain frequency range. The ro4003 range and similar Rogers materials are greater than this.

Above 500 MHz, the RO4003 shines in situations calling for extremely high frequencies. Regularly printed circuit boards, in contrast, can’t get used for frequencies that high. When submerged in liquid, your PCB material of choice should have a water absorption value of zero. In general, compounds have absorption values between 0.01 and 0.20 percent.

The thermal and electrical properties of the material have a direct bearing on the absorption percentage. The impact on the material’s thermal and electrical properties grows proportionally with the absorption percentage. As a result, productivity and efficiency will increase.

In contrast to other common printed circuit boards, the RO4003 has the lowest absorption value. Due to this, they prove to be helpful in hazardous and unsteady settings. The ro4003 is well-suited for use in aerospace and defense applications. In low-exhaust regions such as typical switchboards, the more common PCBs can be advantageous.

There is a difference between ro4003 and regular PCBs in terms of cost. In comparison, the ro4003 is quite pricey. Because of its superior quality, of course. Rogers’s content also ranks highest in terms of how well it performs. The quality and quantity of the materials you use directly affect the final pricing.

What is the difference between Rogers 4003 & Roger PCB Series?

The Rogers 4003 PCB series is slightly different from the rest of Roger’s PCB offerings. The criteria and effectiveness are at play here.

Even though the Rogers ro4003 and 4350B are very similar, there are some minor changes in how they work. The UL 94V-0 flame resistance standard is the most eye-opening.

Since Rogers 4350 incorporates flame-resistant technology, it has been awarded the UL 94V-0 standard’s highest rating. This innovation guarantees that the product is RoHS-compliant. Although it meets all other UL requirements, the Rogers 4003 does not have a UL 94V-0 rating.

When heated, this material immediately catches fire. In contrast to the Roger 4350B printed circuit board, however, the Rogers 4003 gets built using non-hazardous components. These materials are also free of harmful halogens.

Is Multilayer circuit board feasible with Rogers 4003?

Rogers 4003 can be used to create multilayer PCBs. This is conditional on the specifications of your infrastructure. The multilayer printed circuit board is manufacturable from either 100% Roger 4003 laminates or from a hybrid of several materials, like FR4 and Roger 4003.

This combination will produce a high-performance PCB at a reduced cost compared to full-layer Roger 4003 boards. It’s important to route the signal through the center of the PCB rather than on the prepreg’s surface.


The Rogers RO4003 PCB has fantastic TC for use in radio frequency systems. It plays an important role in the automotive, aerospace, and telecommunications sectors and is the favored choice of RF radio circuit designers due to its broad frequency range. For a professional electronic designer to make a useful IC using this component, they need to study its design and its advantages.

The Rogers RO4003C has many benefits, including its low price and simple manufacturing process. Its construction, composed of hydrocarbon-based components, is the single major flaw. These can burn slowly yet are extremely reactive to oxygen. The Rogers RO4003 also lacks fireproofing. Therefore it would be foolish to use it around open flames. In addition, its CTE is forty-six ppm/C, which is rather low for PCBs of this class.
