PCB Material Fr4 Substrate PCB Board Manufacturing Service

As you know, the Printed Circuit Board plays a vital role in electronic products, so you need to consider how to choose the right material in your PCB Manufacturing. JHYPCB can offer you the lowest possible costs and the very finest in high-quality PCB fabrication and high-quality PCB Assembly. However, there are many different types of PCB materials, such as FR-4 material, HDI material, Rogers PCB material, and so on. In general, we use the standard FR-4 material for the Printed Circuit Boards to reduce product costs, which is a good option because FR-4 material is affordable and useful for many applications. However, FR-4 material is not the only type of PCB material; comparing to PCB material, FR-4 material, and Rogers material is essential.


Fr4 PCB Material
PCB Material Fr4


What is FR4?



FR4 is a standard defined by the NEMA (National Electrical Manufacturers Association) for a glass-reinforced epoxy resin laminate.

"FR" indicates the material is flame-retardant, and the "4" indicates woven glass-reinforced epoxy resin. Single or double-sided PCB structures consist of an FR4 core and top and bottom copper layers. Multilayer PCB boards have additional prepreg layers between the center core and top and bottom copper layers. The core consists of a substrate with copper covering, also referred to as a copper-clad laminate(CCL). The core, laminate, and prepreg may all be FR4 with the copper sheets between the signal and ground layers. FR4 is the most common material grade that comprises fabricated circuit boards.

FR-4 or FR4`s properties and characteristics make it very versatile at an affordable cost. Before the explosion of multilayer PCBs, there were many alternative board materials to FR4. These included FR2, CEM 1, and CEM 3, which were paper-based. However, the strength of FR4, especially for multilayer PCB boards, was a significant factor in separating it from alternatives to become the industry standard. Therefore, Most PCBs are made using FR4 as the base material.


FR4 materials and characteristics



Its glass transition (TG) is 115°C to 200°C for the High TGs or HiTGs, depending on the manufacturing methods and the resins used. A standard FR-4 PCB will have a layer of FR-4 sandwiched between two thin layers of laminated copper.

FR-4 uses bromine, a so-called halogen chemical element that is fire resistant. It replaced G-10, another less resistant composite, in most of its applications.

FR4 has the advantage of having an excellent resistance-weight ratio. It does not absorb water, keeps high mechanical strength, and has an excellent insulating capacity in dry or humid environments.


Examples of FR-4



  • Standard FR4: as its name indicates, this is the standard FR-4 with heat resistance of the order of 140°C to 150°C.
  • High TG FR4: this type of FR-4 has higher glass transition (TG) of around 180°C.
  • High CTI FR4: Comparative Tracking Index higher than 600 Volts.
  • FR4 with no laminated copper: ideal for insulation plates and board supports.
  • There are more details of the characteristics of these different materials later in the article.


Factors to consider when choosing the thickness



  • Compatibility with components: even though FR-4 is used to produce many types of the printed circuit, its thickness affects its components. For example, THT components are different from other components and require a thin PCB.

  • Space-saving: space saving is essential when designing a PCB, particularly for USB connectors and Bluetooth accessories. The thinnest boards are used in configurations in which space-saving is crucial.

  • Design and flexibility: most manufacturers prefer thick boards to thin ones. Using FR-4, if the substrate is too thin, it would be at risk of breaking if the board dimensions were increased. On the other hand, thicker boards are flexible and make it possible to create V-grooves.

  • The environment in the PCB that will be used must be considered. For an electronic control unit in the medical field, thin PCBs guarantee reduced stress. Boards that are too thin - and therefore too flexible - are more vulnerable to heat. They can bend and take on an undesirable angle during the component soldering steps.

  • Impedance control: the board thickness implies the dielectric environment consistency, in this case, FR-4, which facilitates impedance control. When impedance is an essential factor, the board thickness is a determining criterion to be taken into account.

  • Connections: the type of connectors used for a printed circuit also determines the FR-4 thickness.

The Difference Between FR-4 Material and Rogers Material


1. FR-4 material is cheaper than Rogers material.
2. Comparing to FR-4 material, Rogers material is great with high frequencies.
3. FR-4 material has a high Df or dissipation factor than Rogers material, suffering more signal loss.
4. In impedance stability, Rogers material has a wider range of Dk values than FR-4 material.
5. For dielectric constant, FR-4 features a Dk of about 4.5, which is lower than Rogers material with around 6.15 to 11.
6. In temperature management, Rogers material has a less variation comparing to FR-4 material.


When is FR4 Not the Best Material For Your Board?


FR4 is indeed a good standard or default option for your board material in most cases. However, there are cases where FR4 is not the best material for your board, as listed below.

  • If lead-free soldering is required

If your boards will be distributed in Europe and must adhere to The Restriction of Hazardous Substances Directive (RoHS) or your client necessitates that lead-free soldering be used, then you may want to explore other material options. This is due to the fact that reflow temperatures for no-lead PCBA(Lead-free PCB Assembly) may reach as high as 250°C, which substantially exceeds the Tg for many versions of FR4.

  • If high-frequency signals are used

At high frequencies, FR4 boards are not able to maintain a constant impedance and reflections may occur that negatively impact signal integrity. This is a consequence of the relatively high value for dk.

  • If the board will be exposed to extremely high temperatures during operation

It is also ill-advised to use FR4 if the PCB will be required to operate in an environment under extremely high temperatures. An example would be near the engine compartment of an aerospace vehicle.


FR4 is rightly the most used material in PCB construction. Boards made from FR4 are strong, water resistant, and provide good insulation between copper layers that minimizes interference and supports good signal integrity. However, at high frequencies and in environments, FR4 is not the best material to use for your boards. At JHYPCB, the industry leader in fast, high-quality PCB Prototype and low-volume manufacturing, we are capable to meet your board material needs for any case. We will work with you to help you select the materials that will best implement your design intent.
