what is FR4 PCB board?

FR4 PCB board is the standard name used in PCB manufacturing. FR stands for Flame retardant. The number 4 is regarded as a typical rating for the material. FR4 PCB boards are generally considered composite structures, and their fiberglass components play a vital role in providing the essential structural stability for FR4. Epoxy is essential because it provides the right rigidity for the FR4 PCB material.

FR4 PCB board material benefits

The FR4 PCB board material is water resistant, strong and has excellent insulation, reduced interference and excellent signal integrity. Other benefits of using FR4 PCB board are :

  1. 1. FR4 PCB board is a cheap material.

  2. 2. FR4 PCB board material has a strong dielectric signal.

  3. 3. FR4 PCB board material is light weight.

  4. 4. FR4 PCB board material has excellent electrical loss characteristics.

  5. 5. FR4 PCB board material color is light green or yellow, suitable for any household appliances.

what is FR4 PCB material?

FR4 PCB is a grade of flammability material code, and is also one of the commonly used boards. FR4 PCB material is a material specification that can self-extinguish resin material after combustion. FR4 PCB material is not a material name but a material class. FR4 PCB material is generally divided into FR4 PCB material rigid board and FR4 PCB material thin board. The technical indexes of FR4 PCB material include bending strength, peeling strength, thermal shock performance, flame retardant performance, volume resistance coefficient, surface resistance, dielectric constant, dielectric loss Angle tangent, glass transition temperature Tg, dimensional stability, maximum service temperature, warping degree, etc. When selecting FR4 PCB materials, pay attention to the thickness of the FR4 PCB board.

A suitable FR4 PCB material must be thin, facilitating the development of PCB boards with limited space. The reason for using the thin FR4 PCB material is because it can accommodate many fragile components and save space on large equipment. The thin flexible FR4 PCB material can be used in medical devices and automotive equipment products. The thickness of the FR4 PCB material affects the weight of the PCB board and component compatibility.

Differences between FR4 PCB material and Rogers pcb material

Many pcb manufacturers and suppliers will use a variety of materials in the production of PCB boards, among which FR4 PCB material and Rogers pcb material are the most used. The following is the difference between FR4 PCB material and Rogers pcb material.

1. FR4 PCB Price

FR4 PCB material and Rogers pcb material vary in price, the cheapest is FR4 PCB material, Rogers pcb material is twice the price. FR4 PCB material has low cost and is favored by pcb manufacturers because of its low processing cost.

2. FR4 PCB high frequency

FR4 PCB material is not suitable for manufacturing PCB boards for high frequency applications.

3. FR4 PCB Df/dissipation

FR4 PCB material and cost are not the only determining factors in assessing their value and performance. Df or loss factor is also a determining factor. FR4 PCB material and Rogers pcb material products have higher Df values, especially at high frequencies.

4. FR4 PCB impedance stability

Rogers pcb material is used where high frequencies and temperature variations are required.

5. FR4 PCB dielectric constant

Compared to the dielectric constant, Rogers pcb material has a dielectric value of 6.15 to 11, which is higher than FR4 PCB material's dielectric value of 4.5.

6. FR4 PCB space application

The materials used to make PCB boards for space exploration are the most important. FR4 PCB material and Rogers pcb material are two materials that are very different in this application. FR4 PCB material does not meet the requirements of space equipment in terms of manufacturability, cost, electrical stability and durability. Rogers pcb material is the right choice for space applications because of its low gas release properties.

FR4 PCB material properties

FR4 PCB material properties are as follows :

  1. 1. Vertical laminar bending strength of FR4 PCB material properties

  2. 2. Parallel layer impact strength of FR4 PCB material properties

  3. 3, FR4 PCB material properties insulation resistance after immersion

  4. 4. Vertical laminar electrical strength of FR4 PCB material properties

  5. 5, FR4 PCB material properties of parallel layer breakdown voltage

  6. 6. Relative dielectric constant of FR4 PCB material properties
