PCB Core By Thickness

0.5 mm Core PCB

The 0.5 mm Core PCB is the minimum thickness we can offer for your applications. In addition, they are highly in demand for thinner devices, such as sensor cards and other chip-like devices. Additionally, it has a limited surface finish option.

0.8 mm Core PCB

The 0.8 mm Core PCB can be a suitable option for the compact size of electronic devices. However, selecting a thinner thickness can restrain your choices for its protective treatments. Moreover, we suggest going for one layer of core for this.

1.0 mm Core PCB

The 1.0 mm Core PCB may be applied to applications requiring signal transferring; however, it may not be possible in some cases. Therefore, we highly recommend telling us your specifications and purposes before choosing its thickness.

1.2 mm Core PCB

The 1.2 mm Core PCB can be your perfect option if your applications require a considerable number of layers since it can reduce the overall thickness of the board up to this size. In addition, it can already support almost all surface polish options.

1.6 mm Core PCB

The 1.6 mm Core PCB is the thickness we can recommend if you’re seeking a more cost-efficient alternative since it is the standard thickness in the market. Since using a non-standard thickness can increase production costs due to their specificities.

1.8 mm Core PCB

The 1.8 mm Core PCB can be ideal for applications that require heavier components incorporated into it since choosing a much thinner thickness can lead to breaking. However, it can be less flexible if compared to other thin thicknesses.

What is PCB Core?

To put it simply, a PCB Core is a rigid material; it acts as a hardcore foundation coated with one or two aspects of copper.

They are widely used in the fabrication of Single-Sided, Double-Sided, and Multilayer boards. In addition, it is composed of titanium epoxy laminates and copper traces that are mainly the elements of FR4 material.

Furthermore, it is referred to as an epoxy laminated glass-reinforced sheet. Moreover, its layers are bounded together through a prepreg material as the core gets heated.

It has been categorized by the expert as a core panel and a core in every circuit board manufacturing. Also, it comes with various copper, width, and firmness. Inquire today!

What is PCB Core?
Difference Between PCB Core and Prepreg Material

Difference Between PCB Core and Prepreg Material

Before we discuss their differences, we’d like to share with you the definition and purpose of a prepreg to further assess the two.

Basically, to create the proper insulation between the copper and the PCB core, engineers pack this conductive material (prepreg); it serves as a form of isolation.

In terms of distinctions between the core and laminate, they do not have that much of a difference. Since a core is composed of a prepreg laminate that is cured, hardened, and pressed using heat. Additionally, they coat it on both sides of the board using copper foil.

In essence, the prepreg laminate is what binds the core materials; hence, they are termed glue. Feel free to message us for further details concerning this.

Features of a PCB Core

We have the following distinct characteristics of a PCB Core:

  • TG Capability – It has a High TG value of 130°C up to 170°C.
  • High Decomposition Temperature – It possesses a value of up to 320°C.
  • CTE Value – It is categorized as high; it has several, about 10 to 70 ppm.
  • Thermal Conductivity – It falls under high distinction at 386 W/M-°C.
  • Flame Resistance – It has a value of 4.5 Er and is considered high.
  • Volume Resistivity – It has a value of 106 to 1010 MΩ/cm and is regarded as high.
  • Surface Resistivity – It has a value of 106 to 1010 MΩ/square.
  • Dielectric Tangent – It possesses a low value.

PCB Core Fabrication

What are the Dielectric Materials of PCB Core?

In simple terms, a dielectric material is deployed in every PCB with a hapless electricity pilot, referred to as an insulating layer.

The dielectric material primarily comprises porcelain, mica, silica, and other metal oxides. Also, minor loss of electrons leads to efficient dielectric.

Whenever the dielectric substance hits its highest potential, it will immediately start to transfer the currents through a voltage; thus, it becomes more powerful.

One factor that determines this phenomenon is the material’s dielectric constant. As for this particular board, it has a value of 4.5.

If you have any questions relating to this matter, kindly message us.

Advantages of PCB Core

Although there are only three (3) primary benefits of utilizing a core, it can significantly affect the overall performance and output of your PCB.

Firstly, it is a highly thermally conductive material; thus, it proposed a better efficiency. It wouldn’t be possible without the assistance of copper.

Secondly, it is more durable. The capability of the copper to have high heat absorption capability and less distortion rate brings more reliability to the overall performance.

Finally, it is renowned for being economical since copper is a natural substance that can be easily recycled, an ecological solution.
