Introduction
PCB board material is one of the most important components in the production of Printed Circuit Boards. The material that is used to manufacture PCB boards is an essential aspect of the whole process. From the design stage to the final manufacturing process, PCB board material plays a crucial role in determining the overall quality of the PCB board.
In this article, we will focus on PCB board material manufacturers and the parameters that one should consider when selecting a PCB board material for PCB production.
PCB board material manufacturers
There are many PCB board material manufacturers in the market. Choosing the right one is critical to the success of any PCB project. Some of the most popular and reputable PCB board material manufacturers are:
1. Rogers Corporation
2. DuPont
3. Isola Group
4. Ventec International Group
5. Shengyi Technology
6. Nanya PCB
7. Hitachi Chemical
8. Panasonic Electronic Materials
These companies offer a wide range of PCB board materials that are suitable for different types of PCB production.
PCB board material parameters
When selecting a PCB board material, there are certain parameters that one should consider. These parameters include:
1. Dielectric constant and loss tangent:
The dielectric constant and loss tangent of a PCB board material determine the signal speed and signal attenuation properties of the PCB board. It is essential to select a PCB board material that has a low dielectric constant and loss tangent to ensure optimum signal transmission.
2. Thermal conductivity:
The thermal conductivity of a PCB board material is crucial for heat dissipation. Selecting a PCB board material with high thermal conductivity ensures optimal heat dissipation properties of the PCB board.
3. Tg (glass transition temperature):
Tg is the temperature where the material changes from a glassy state to a rubbery state. Selecting a PCB board material with a higher Tg ensures that the PCB board can withstand higher temperatures during the manufacturing process.
4. CTE (coefficient of thermal expansion):
The CTE of a PCB board material determines the material’s expansion and contraction properties during temperature changes. Selecting a PCB board material with a low CTE ensures that the PCB board can withstand thermal stress that occurs during the manufacturing process.
5. Moisture absorption:
The moisture absorption property of a PCB board material is crucial for the PCB’s performance in humid environments. Selecting a PCB board material with low moisture absorption ensures that the PCB board can withstand humid conditions without affecting its performance.
Conclusion
In conclusion, PCB board material is a critical component in the production of PCBs. Selecting the right PCB board material is just as important as designing the PCB circuit itself. By considering the parameters discussed in this article, one can make an informed decision when selecting a PCB board material manufacturer and choosing the right material for PCB production.
