Comparison of Epoxy Sheet Materials: Differences in Temperature Resistance between G10 and FR4

As a versatile engineering material that plays an important role in the electronics and electrical industries, G10 and FR4 epoxy sheets, two common types of epoxy sheets, differ significantly in their temperature resistance properties, which directly affects their suitability for specific application scenarios.

G10 epoxy sheets are known for their excellent temperature resistance, often able to remain stable at higher temperatures, with heat resistance up to 155°C or higher. This high-temperature stability makes G10 board ideal for insulating components in high-voltage electrical equipment, transformers and motors. In these applications, G10 board is able to withstand prolonged thermal stress without losing its physical or electrical properties.

In contrast, FR4 epoxy boards, while widely used in the electronics industry to manufacture printed circuit boards (PCBs), typically have lower thermal performance than G10 boards.FR4 boards, which typically have a thermal resistance of around 130°C, are suitable for most commercial and industrial electronics applications, but may not be the best choice in more extreme temperature conditions.

When it comes to material selection, engineers need to decide whether to use G10 or FR4 epoxy board based on the specific temperature requirements of the application. If the project needs to operate in a high temperature environment, the high heat resistance of G10 board will be a key factor. However, for cost-sensitive applications with not particularly high temperature requirements, FR4 boards may provide adequate performance while being more cost-effective.

Furthermore, in addition to temperature resistance, G10 and FR4 epoxy boards differ in terms of electrical insulation properties, mechanical strength and processability. the high mechanical strength of G10 boards makes them suitable for larger mechanical loads, while FR4 boards are widely used in PCB manufacturing because of their good processability.

To summarize, G10 epoxy boards and FR4 epoxy boards each have their advantages and limitations. Understanding the differences in their temperature resistance properties will help engineers and designers make a more appropriate material choice based on the specific needs of the project.

FR4, full name FR-4 epoxy fiberglass sheet, is a high-performance composite material. The following will be a detailed introduction from the definition of FR4, characteristics, applications, and the selection of processing tools.

First, FR4 material introduction

FR4, that is, FR-4 epoxy glass fiber board, is a composite material made of epoxy resin and glass fiber cloth. FR4 is the substrate used in PCB, is a category of sheet material. The “FR” stands for Flame Resistant, and the “4” indicates the performance grade. It has excellent electrical insulation properties, flatness and mechanical strength, as well as good heat and moisture resistance. Therefore, FR4 has been widely used in the electronic field, such as for the production of PCB test fixtures, electrical equipment insulation spacer, transformer insulation board.

Second, the characteristics of FR4 material

1. Stable electrical insulation performance: FR4 material has a high resistivity, can effectively prevent current leakage, to ensure the safe operation of electronic equipment.

2. good flatness: FR4 material has a flat surface, which is conducive to the precise installation and stable operation of electronic components.

3. High mechanical strength: FR4 material has high mechanical strength and can withstand certain external forces and impacts.

4. Good heat and moisture resistance: FR4 materials can maintain stable performance in high temperature and high humidity environment, suitable for a variety of harsh working environment.

Third, the application of FR4 materials

Due to the excellent performance of FR4 material, it has a wide range of applications in the electronic field. For example, it can be used as PCB test fixtures, electrical equipment insulation spacer, transformer insulation board, motor insulation parts. In addition, FR4 material can also be used to make precision vernier gears, precision test plates and other high-precision parts.

Fourth, FR4 processing tool selection

When processing FR4 materials, it is crucial to choose the right tool. Common processing methods include drilling, cutting and milling. For drilling, the general use of drills and drilling machines for processing; cutting can use special cutting tools; and milling requires the selection of suitable milling cutters. These tools need to be characterized by high hardness, high wear resistance and high precision to ensure processing quality and efficiency.

For the processing of FR4 material, it is recommended to use carbide tools or high-speed steel tools. These tools have high hardness and wear resistance and can effectively machine FR4 materials. At the same time, according to the specific processing needs and process requirements, you can also choose different shapes and sizes of tools to meet the actual needs.

V. Summary

As a high-performance epoxy glass fiber composite material, FR4 has a wide range of application prospects in the field of electronics. Understanding its material properties, application areas and the selection of processing tools is crucial to ensure the quality and efficiency of processing.
