High TG PCB Series
FR-4 refers to a grade of epoxy fiberglass material where the FR stands for “flame retarding”. The TG130 refers to the glass transition temperature and indicates that this material will begin to deform at 130 ℃. FR-4 is the most common substrate material for rigid PCBs, particularly prototypes. In the PCB, the pre-preg and core will be made of this material.
The general median Tg is greater than 150-160 centigrade, As a general rule the higher the Tg, the more stable the material is during the PCB manufacturing process and assembly. If you are not sure about what material you should specify, ask your PCB manufacturer. They know their process and they know what they are capable of.
FR-4 materials with higher glass transition temperatures are available in the Advanced PCB service. High TG FR-4 (TG170) boards can withstand deformation at higher temperatures of up to 170 ℃ and are suitable for extreme temperature applications. If you want to make multi-layers (more than 10 layers) with blind & buried via.
The typical FR4 TG175 material is Nelco N4000-6, which is a high-Tg epoxy laminate and prepreg system that provides a wide range of performance versatility and ease of processing for demanding high-layer count applications. It has excellent electrical properties for a standard loss material, supporting advanced technology PWB designs, and is suitable for high-layer count, sophisticated PWB designs.
PCBMay manufactures PCBs with Tg value of up to 180°C. Normally the High TG180 PCB is ITEQ 180 and 370HR. When you need high class items, use ITEQ IT180A (TG 180) which is also RoHS compliant. ITEQ IT180A (TG 180) is comparable in quality and to Isola 370HR (TG 180), which are made using a patented high performance 180°C Tg FR-4 multi-functional epoxy resin system.
PTFE materials are suited for high-frequency applications. At RF and Microwave frequencies, the dielectric constant of standard FR-4 Material (approx. 4.5) is often too high, resulting in significant signal loss during transmission across the PCB. Fortunately, PTFE materials boast dielectric constant values as low as 3.5 or below, ideal for overcoming high-speed FR-4 limits.

High TG PCB: The Ultimate FAQ Guide
The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from hard, glassy material to a soft, rubbery material.
We understand that discriminating buyers like you require this information.
As a result, we’ve put up this FAQ guide to assist you, our most valued client, in learning everything there is to know about high Tg PCBs.
Circuit board material must be flame-resistant, it can’t be burned at a certain temperature and only be softened. The temperature point is called the glass transition temperature (Tg).
The higher Tg point means a higher temperature requirement during lamination.
And the boards will be hard and crisp, which will affect the hole and the electrical properties.
In recent years, there are more and more customers requested to manufacture PCB with high Tg, in the following we would like to describe what is high Tg PCB.
Tg is the glass transition temperature of a Printed Circuit Board. It is that temperature at which the base material of a PCB starts to transform from a brittle condition to a soft, elastic one.
A PCB whose glass transition temperature (Tg) is greater than 170 ℃ is known as a High Tg PCB. Generally speaking, Tg values for PCBs is between 130 and 170 ℃.
High TG PCB is the transition temperature of the PCB at which the brittle and hard material of a PCB starts to melt into a softer and delicate material.
It is an important property in PCBs.
The demand for High TG PCB in the PCB industry has suddenly increased.
The PCB has a temperature higher than 170 is termed as High TG PCB.
All the PCBs have manufacturing of a different material.
Some are harder than the other is. Therefore, the values of transition temperature for every kind are different.
Usually, the high transition temperature lies between 120 to 170 degrees.
The High TG PCB
If your product is working at 130 degrees or higher, you will need a High TG PCB.
For a High TG board, there is a need for higher temperature. During lamination, while processing a printed circuit board.
When making a printed circuit board at the TG temperature, it is hard and crisp. In addition, it has better electrical properties.
The printed circuit boards of low quality deform and melt at higher temperatures. They lose their electrical and mechanical properties.
The higher the transition temperature of a High TG printed circuit board, the better the quality like heat resistance, chemical resistant, mechanical stability, and much more.
Here is some popular High Tg board raw material in the market:
- S1170 & S1000-2: Shengyi Technology
- FR406, FR408, IS410 & DS370HR: Isola
- IT180: ITEQ
- MCL-E-679: Hitachi
- N4000-6 & N4000-11: Nelco
Every PCB has a different Tg value based on its substrate. If the operating temperature of the board exceeds its Tg value, the board will begin to change its state which will have an adverse effect on the functionality of the PCB.
High Tg boards perform better at high temperatures with better stability as the substrate provides better heat resistance, chemical, and mechanical stability to the board.
When selecting a PCB, the Tg value should be at least 20-25 degrees Celsius higher than the expected operating temperature of the device in which the PCB is used. For instance, if you have a PCB with a Tg value of 130 degrees Celsius then the working temperature of the device should be lower than 110 degrees Celsius.
Withstand High Power Density Designs: If a device has high power density with a very high heat generation rate then High Tg PCB is a good solution for heat management.
Reduction in the heat generation of a regular PCB can be accomplished by using a larger PCB, changing the design and power requirements of a device.
Alternatively, a high TG board can be used.
Ideal for Multilayer & HDI PCBs: Multilayer & HDI PCBs are more compact and have very dense circuits which can result in high levels of heat dissipation.
High Tg boards are often used in these kinds of PCBs to ensure reliability during operation.
Higher Stability: If the Tg of a PCB substrate is increased then it will automatically increase the heat resistance, moisture resistance, chemical resistance, and stability of the device.
We can manufacture High-Tg PCBs with a Tg value of up to 180°C.
The following table lists some of our commonly used materials for High-Tg PCB production.
| Material | TG (DSC, °C) | Td (Wt, °C) | CTE-z (ppm/°C) | Td260 (min) | Td288 (min) |
| S1141 (FR4) | 175 | 300 | 55 | 8 | / |
| S1000-2M (FR4) | 180 | 345 | 45 | 60 | 20 |
| IT180 | 180 | 345 | 45 | 60 | 20 |
| Rogers 4350B | 280 | 390 | 50 | / | / |
There are many advantages of using a High TG PCB instead of a simple printed circuit board.
These are as follows:
- Higher stability:
If the TG value of the printed circuit board increases, it will increase the stability of the device. The higher the TG value, the higher the stability.
- It is Good for high power density designs:
If your device has a high power density, it will automatically produce high heat. It would be great to use High TG PCB for it as a solution.
You can go for a printed circuit board of larger size to change the power requirements of the printed circuit board when producing high heat.
- In Multilayer PCBs:
The multilayered PCBs are complex ones having multilayers. The heat generation in them is greater as well. Therefore, it is best to use High TG PCB in such cases.

The Designing of the High TG PCB
The chemical features play an important role in the functioning of a High TG board.
You must determine the chemical features before you select the material for the PCB.
Its humidity resistance can withstand high moisture.
Even a lot of moisture cannot cause damage to the High TG circuit board.
The moisture absorption directly affects the working of the High TG board.
The other chemical feature is methylene chloride resistance.
It measures the resistance towards methylene chloride.
The chemical features of High TG PCB directly affect the electrical and mechanical properties of High TG PCB.
When you are subject to higher temperatures, they withstand these high temperatures.
You will need a High TG PCB when your product is operating at a temperature greater than 130 degrees.
It would be safe to use High TG PCB at this temperature compared to a simple printed circuit board.
You will need a high transition temperature printed circuit board for your device when your circuit board is experiencing temperature 25 degrees below than normal transition temperature value.
However, the main reason you need a High TG PCB, is the movement towards RoHS printed circuit board.
So whenever the device has a temperature that is exceeding 130 degrees Celsius, make sure to use High TG PCB in it.
Use high TG PCB rather than a normal printed circuit board.
Stability means that it can withstand any fluctuation.
High TG PCBs operate at temperatures greater than 130 degrees Celsius and they can range up to 170 degrees Celsius.
They are extremely stable and have great mechanical strength.
They are thermally stable. They are thermal stress-resistant and can bear very high temperatures.
They have the stability of their dimensions. It can resist any pressure applied to it as well due to mechanical strength.
They have electrical stability and strengthening as well. They can withstand any voltage changes that occur in any application.
They are chemically stable and have great stability against moisture in its surrounding.
They also have stability against methylene chloride. Excess methylene chloride can cause damage to the High TG PCB. However, they resist it.
The depiction of High TG PCB thermal stability
TG value stands for the transition temperature at which the material starts to lose its original state.
In the case of High TG PCB, It is the temperature at which the High TG PCB starts to lose its brittles, hardness and starts to melt, and becomes softer and elastic.
As a result, the High TG PCB loses its functioning and working.
High TG PCB becomes mechanically unstable.
For a transition temperature value of any material, there is an upper value. At this temperature, the resin decomposes, and the delamination process occurs.
If the working temperature of your device is higher than 130 degrees Celsius, then there is a need of using a High TG PCB.
Also during the lamination process, the higher is the transition temperature, the higher is the temperature requirement.
Therefore, during lamination, higher temperatures will cause the circuit boards to be crisp and hard.
Moreover, with the immense increase in technology, the requirement for High TG PCB in the printed circuit board industry has increased exponentially.
The High TG PCB transition temperature (TG)
Some features directly affect the working and functioning of the High TG PCB.
The High TG PCB is chemically stable.
It means that it can withstand any chemical being present in its environment.
It can absorb any moisture present in its environment.
The presence of moisture can affect the working of the High TG circuit board.
Therefore, moisture present in the surrounding High TG circuit board could be damaging to its working and functioning.
However, the High TG PCB has great moisture absorption capability.
You need to make sure, that no excess moisture is present when you are using the High TG PCB.
No humidity present in the environment is the ideal state for the working of High TG PCB.
In addition, in case you want to remove the moisture present in your High TG PCB, you can use the baking method to remove moisture.
During this process, moisture is forced out of the printed circuit boards. Therefore, it can prevent further damage.
The effect of moisture on High TG PCB
The High TG PCB material is one that can withstand very high temperatures. It can range from 130 degrees Celsius to 170-degree Celsius.
Usually, the manufacturers chose high Tg material to make higher layers of PCB.
When it comes to the selection of material for the making of High TG PCB. You must choose materials that have a high transition temperature value.
This high transition temperature will make it very stable.
Therefore, a very high temperature i-e greater than 170 degrees Celsius would be required to deform or melt it.
Generally, the transition temperature (TG) material used in High TG PCB is FR4.
The transition temperature for FR4 usually lies within 130 degrees Celsius to 140 degrees Celsius.
The higher the transition temperature value of any material, the better is the working and the performance of any circuit board.
The high Tg material is used in almost all high technology devices.
It has its uses in computers, LED lights, radar systems, the aerospace industry, and for military purposes.
If the Tg value is higher, a greater amount of energy and temperature would be required to degrade it.
The FR4 Material Used for High TG PCB
The manufacturing process is very crucial and requires great precision.
The first step in manufacturing is the designing of the High TG PCB.
In this step, make the design of a High TG board and then finalize it.
Make the design of the High TG PCB and make sure it is ready to use.
You can use any software for designing the High TG PCB.
Once you finalize the design, check for the frequency of the signals that are required to use in the manufacturing of High TG PCB.
Once it is determined, gather all the components.
Start routing connections on the board. Determine every component that is going to be used.
Start the assembly of the components.
Determine all the grounds like the ground plane and power plane.
Check for all the high-frequency signals and signal return paths.
In this way, perform the manufacturing of the High TG PCB.
The manufacturing process of High TG PCB
The High TG circuit board has the ability to withstand very high temperatures.
The range of temperature that a High TG PCB can withstand, lies within 130-degree Celsius to 170 degrees Celsius.
After this temperature, the High TG PCB starts to deform and melt.
It loses its hardness and brittleness after this temperature.
The temperature requirement at which it loses its state is known as the Tg temperature i-e, the transition temperature of the High TG PCB.
The greater the transition temperature of the printed circuit board, the greater is its working.
It means that it is one of the best circuit boards. Compared to the ordinary circuit board.
Ordinary circuit boards have lower transition temperature values, which means lesser heat stability.
Its demand has increased immensely over the past few years in the printed circuit board industries.
Due to its high thermal stability properties, it has its uses in almost all kinds of devices, making it one of the printed circuit boards that have ever existed.
Aerospace, telecommunication, defense and military, and automobile industries have great use of High TG PCB.
The Maximum Temperature of the High TG PCB
The printed circuit boards have a temperature limit at which they can work and function properly.
However, if they exceed the temperature limit, the printed circuit board loses its state and starts to deform.
In addition, when the circuit board melts, it loses all its mechanical and electrical properties.
The usual hard form of the printed circuit board is gone, due to excessive temperature administered on it.
It is known as the temperature limit of the printed circuit board.
Usually, the temperature range for it is below 130 degrees Celsius.
However, in the case of High TG PCB, when the temperature is applied above 130 and below 150 degrees, the High TG PCB keeps its integrity and state.
Nevertheless, when the temperature exceeds 170 degrees Celsius, it starts to lose its brittleness and hardness. It is known as the transition temperature for High TG PCB.
Due to the higher transition temperature of the High TG PCB, it has well know physical features that make it an outstanding printed circuit board.
