TG150 PCB Board

When engaging in circuit board design, one cannot overlook the significance and role of FR4, commonly referred to as the epoxy substrate. This material not only provides structural support for the circuit but also serves as a platform for circuit construction. The choice of printed circuit board material is a critical decision among various other components of a PCB. PCBs can be designed as multi-layer, single-layer, or double-layer, with different materials such as FR4 TG150, FR4 TG170, FR4180, RF4 TG130, RF4 TG260, and more.

In this article, we will focus on understanding the characteristics and advantages of TG150 PCBs as a substrate type for printed circuit boards. This discussion will provide valuable insights into TG150 and why it is worth considering when procuring PCB substrates.

Definition of TG150 PCBs

The term “TG150 printed circuit board” refers to a circuit board that is manufactured using a TG150 substrate material. In the context of printed circuit boards, TG stands for glass transition temperature, which denotes the gradual and reversible transformation of an amorphous material from a solid and rigid state (referred to as “glassy”) to a rubbery and viscous state when exposed to higher temperatures. It is important to note that the TG value is typically lower than the melting temperature of the corresponding crystalline material state.

Materials with glass transition temperature properties are often chosen for their burn resistance and ability to deform or melt within specific temperature ranges. In the case of TG150 PCBs, they utilize a medium TG material, which means that the glass transition temperature falls above the range of 130 degrees Celsius to 140 degrees Celsius but remains below the threshold of 170 degrees Celsius or higher. It is worth mentioning that the higher the TG value of a substrate, typically composed of epoxy, the greater the stability of the printed circuit board.

By utilizing TG150 PCBs, designers and manufacturers can ensure that the circuit boards can withstand higher temperatures and maintain their structural integrity and performance. This makes TG150 an appropriate choice for applications where thermal stability is a critical factor.

Properties and Advantages of TG150 PCBs

1.Thermal Stability:

TG150 PCBs exhibit excellent thermal stability, making them suitable for applications that involve elevated temperatures. The material can withstand higher operating temperatures without significant degradation, ensuring reliable performance even in demanding thermal environments.

2.Mechanical Strength:

TG150 PCBs offer robust mechanical strength and durability. They have high resistance to warping, bending, and mechanical stress, ensuring the integrity and longevity of the PCBs. This property is particularly important in applications where the PCB may undergo physical stress or vibration.

3.Electrical Performance:

TG150 PCBs provide good electrical performance, including low signal loss and controlled impedance. They have low dielectric loss and high insulation resistance, allowing for efficient signal transmission and reliable operation of electronic components.

4.Flame Resistance:

TG150 material is inherently flame-resistant, making TG150 PCBs suitable for applications where fire safety is crucial. The material has excellent self-extinguishing properties, which helps prevent the spread of fire in case of electrical faults or accidents.

5.Chemical Resistance:

TG150 PCBs exhibit good resistance to various chemicals, including solvents, acids, and bases. This property ensures that the PCBs can withstand exposure to different substances without experiencing significant degradation or performance issues.


TG150 PCBs offer a good balance between performance and cost. They provide many of the desirable properties of higher-grade materials while being more affordable. This makes TG150 PCBs a cost-effective choice for applications that require enhanced thermal stability without the need for more expensive materials.

7.Availability and Compatibility:

TG150 material is widely available in the PCB industry, and many manufacturers offer TG150 PCB fabrication services. The material is compatible with standard PCB manufacturing processes, making it easy to incorporate into existing production workflows.

By leveraging the properties and advantages of TG150 PCBs, designers can develop reliable and high-performance circuit boards suitable for a wide range of applications, including those with demanding thermal and mechanical requirements.

Industries That Benefit from TG150 PCBs

TG150 PCBs, with their higher glass transition temperature (Tg) and improved thermal properties, are beneficial in various industries where high-temperature applications and reliability are crucial. Here are some industries that can benefit from TG150 PCBs:

●Aerospace and Defense
●Industrial Electronics
●Energy and Power Systems
●Oil and Gas
●Medical Devices
●Research and Scientific Instruments

These are just a few examples of industries that can benefit from TG150 PCBs. The higher Tg and improved thermal properties of TG150 materials make them suitable for applications where temperature resistance and reliability are critical factors.

Comparison of TG150 with Other FR4 Materials

TG150 is a specific type of FR4 material with a higher glass transition temperature (Tg) compared to standard FR4. Let’s compare TG150 with other FR4 materials to understand their differences:

1. Tg Value: The Tg value of TG150 is typically around 150°C or higher, while standard FR4 materials generally have a Tg value of around 130-140°C. The higher Tg of TG150 indicates a greater ability to withstand elevated temperatures without significant changes in its properties.

2. Thermal Stability: TG150 offers improved thermal stability compared to standard FR4. It can handle higher temperatures and thermal cycling without experiencing delamination, warping, or degradation of electrical properties. Standard FR4 may be more prone to thermal stress and dimensional changes under extreme temperature conditions.

3. Mechanical Strength: TG150 typically exhibits better mechanical strength and dimensional stability compared to standard FR4. It maintains its structural integrity even under thermal stress and can withstand higher levels of vibration and mechanical strain.

4. Electrical Performance: The electrical performance of TG150 and standard FR4 can be similar, depending on the specific material formulations. Both types of materials offer good electrical insulation properties, low dielectric loss, and high breakdown voltage. However, TG150 may have a slight advantage in maintaining consistent electrical performance at higher temperatures.

5. Cost: TG150 materials are often more expensive than standard FR4 due to their enhanced properties and specialized formulations. The higher Tg and improved thermal stability of TG150 come with increased manufacturing costs.

When choosing between TG150 and standard FR4 materials, it’s essential to consider the specific requirements of your application. If your design operates under elevated temperatures or requires improved thermal stability, TG150 may be a better choice. However, for applications with lower temperature requirements and cost-sensitive considerations, standard FR4 can still provide satisfactory performance. Consulting with PCB material suppliers or manufacturers can help determine the most suitable choice for your specific needs.

TG150 and TG170 Which One is Better?

In the field of PCB manufacturing, it is not uncommon for individuals unfamiliar with the industry to be confused about the differences between Tg 150 and Tg 170. To provide some clarity, Tg refers to the glass transition temperature of a material. For FR4, a commonly used PCB substrate material, the typical Tg range is between 130°C and 140°C. Medium Tg materials have a Tg value above 150°C, while high Tg materials can reach 170°C or even higher, such as 180°C.

When it comes to PCB manufacturing, it is crucial to ensure that the boards are resistant to burning during the manufacturing process and maintain dimensional stability (X, Y, Z). As a general rule, selecting a higher Tg material is preferable. However, it is important to strike a balance, as excessively high Tg values can increase the difficulty of mechanical processing and lead to higher raw material and manufacturing costs. Therefore, it is advisable to choose a substrate that offers both a high Tg value and ease of processing.

The primary consideration when deciding between Tg 150 and Tg 170 PCB materials is the working temperature. If the working temperature is below 130°C/140°C, Tg 150 material would be suitable for your PCB. However, if the working temperature is around 150°C, it becomes necessary to opt for Tg 170 material.
