Rogers FR4 PCB: Types, Properties, And Many Other Things

The Rogers FR4 PCB is a printed circuit board that utilizes the FR4 laminates. The majority of the PCBs are created from FRA or Flame-Retardant Level 4. FR4 is not the actual name of the material, but it’s the grade of the material. Here, level 4 is known as the 4th grade of the retardant material.

The composition of this specific material contains epoxy resin and fibers of glass. Moreover, the Rogers FR4 PCB is said to carry anti-flame properties, mainly because of the FR4 material. Also, the composition of the FR4 material is according to the UL94V – 0 standards.

Since it’s created with the FR4 material, the Rogers FR4 PCB gets equipped with high performance and strength. It will also carry an excellent ratio between weight and strength. These printed circuit boards cannot absorb water and contain outstanding insulating properties.

What are the Various Kinds of Rogers FR4 PCB?

When it comes to the Rogers FR4 PCB, you will come across various types. Each is different and has its benefits, usage, and features. Some of the most vital ones are:

1. Single Side

The single side rogers FR4 printed circuit boards are created from PCB containing epoxy resin and copper foil on the side.

All its components are also pasted on one side. The size of these types of PCBs comes with a height of 1.5mm, a width of 70mm, and a length of 100mm.

The challenging production process with all the new machinery has made all the products expensive in today’s digital world.

But the single side Rogers FR4 PCB is available in the form of affordable and advanced printed circuit boards.

2. Double Side

The double-sided PCB has copper foil pasted on both sides. Besides, they also have components that are found on both sides of this double-sided PCB. The presence of copper makes these kinds of boards excellent for conduction. Furthermore, the components pasted on both sides provide the path of traces to cross one another.

3. Multiple Layers

The multi-sided FR4 PCB has over two layers. This means this printed circuit board contains 3-layer material for conduction. The core material gets laminated under high temperatures and high pressure to create multi-layer printed circuit boards. When it comes to the components, you will find them pasted on both sides of the rogers FR4 PCB properly.

4. Rigid-Flex

These are another type of printed circuit board that comes with a flexible and rigid core material. Due to such reasons, they are called the rigid-flex rogers FR4 PCB by many people.

The PCB has a flexible circuit, and thin boards are used during their creation because they are much more vulnerable to heat and are flexible. During the soldering process, it can be easily bent to put it into a desirable angle.

Important Things to Know About the Rogers FR4 PCB

All FR4 PCBs can be used with plastic materials with the UL94-0 standard. Here, code 94-0 is written for all the FR4-made PCBs, which displays the guarantee to offer protection to the device from fire propagation during the time when the material gets burned.

Remember, the Rogers FR4 PCB comes with numerous layers of the FR4 pasted right between the dual thin layers of the laminate copper plate. It’s mainly because bromine is utilized for its production, which is called the ‘Halogen Element.’ The standard for the FR4 printed circuit boards is resistance to heat.

During production, these boards get laminated with the help of copper layers within a particular temperature. Besides that, it’s also excellent for board supports that have no laminated copper and insulation. These boards contain a much higher TG, which is about 180 Degree Celsius.

Factors You Should Consider for Rogers FR4 PCB

When you’re thinking of purchasing or opting for these types of printed circuit boards, there are some things you must put under your consideration.

1. The Sheet’s Thickness

Here, the thickness will depend heavily on what you wish to make. If you wish to design printed circuit boards, you will require the thinnest boards for the job. These thin boards will lessen the stress, and when it comes to FR4 material, you will need a thickness of 1 inch to 3 inches.

2. Matching the Impedance

Within the electronic equipment, the matching of the frequency or impedance is highly crucial for high-frequency or low-frequency printed circuit boards. You must pay proper attention to all those points as it will help the boards to run safely. Moreover, it will also tell you about the capacitance within the multiple-sided boards.

3. Spacing

During the design work for the rogers FR4 PCB, space-saving is viewed as one of the vital factors. For all the Bluetooth accessories and USB connectors, the spacing is pretty compulsory, and it will be much better if you go for the thinnest boards when designing the printed circuit boards.

4. Flexibility

Thinner boards are said to be a lot more flexible when compared with thicker ones. The majority of PCB manufacturers utilize thinner boards rather than thicker ones because of this reason. When using the FR4, if the substrates that are utilized are pretty thin and the FR4 PCB area of dimension much more, it will be a great risk. Be sure to check the material and all the other things before taking the next step.

5. Component’s Compatibility

These types of FR4-made printed circuit boards come in various spacing and thicknesses and can also tell you about those components and devices that can be used in the FR4 PCB.

Just like the THT devices are pretty different from all the other devices and need a thinner printed circuit board design, when designing FR4 PCB, you need it’s matching components. Doing so will function and perform perfectly well without causing many problems.

Ending Note

The Rogers FR4 printed circuit boards have become extremely popular across various sectors. They are used in numerous applications, and it’s well-known for their thermal management and flexibility. You will also find these types of PCB boards available in various types in the market. They are carefully created by all the PCB manufacturers, and each of them is double-checked before they are made available to the public.
