FR4 tg is a proprietary organic high-performance thermoset polymer laminate. Its formulation meets the unique needs of semiconductor manufacturing. Tg on PCB measures how well heat moves through the material compared to the generated speed. It is an essential property for thermal management and heat transfer.
Ways of classifying fr4 tg
- We measure Thermal conductivity per unit thickness
- Thermoset organic polymer
- High-Performance thermoset polymer laminate
- We formulate FR4 tg has to meet the unique needs of semiconductor manufacturing
Thermal conductivity per unit thickness
As a BGA package moves through the wafer, it generates heat inside the package. Generally, the wafer itself will not lose much heat to the surrounding atmosphere over a relatively short period. But, after separating the package from a wafer and exposing it to the atmosphere, it will lose heat.
This is due to surface-to-surface thermal conduction. The amount of heat lost will depend on the heat generation rate in the package and the rate it will take away. FR4 tg allows increased heat throughput through the BGA package. It will also help maintain normal production cycle times.
Thermoset organic polymer
The Tg on PCB of FR4 tg was about 80°C, and the Tg on PCB of FR4 tg was about 70°C. The improvement in thermal performance of FR4 tg was due to better Tg on PCB.
FR4 tg is a proprietary organic high-performance thermoset polymer laminate. Its design helps in meeting the unique needs of semiconductor manufacturing.
High-Performance thermoset polymer laminate
FR4 tg can meet the unique needs of semiconductor manufacturing. The FR4 tg is a proprietary thermoset polymer laminate. This laminate is a product of different components. Such as POX and Epoxy resin, creating a high-performance thermoset resin used in BGA packaging applications. The Thermoset polymer laminate chemically binds with an oxygen-cured monomer. It uses a process similar to casting/molding.
FR4 tg can meet the unique needs of semiconductor manufacturing
Due to the inherent weakness in FR4, it changes into a glass-reinforced epoxy laminate. We use this glass-reinforced material for high-power applications, such as Aerospace, Automotive, and Defense markets. There are some advantages to using these materials beyond the performance properties of FR4 tg. FR4 tg is practical in BGA packaging applications. Because of its ability to heat and reform over multiple cycles while maintaining the same optical properties.
Is FR4 a PTFE?
FR-4 is not PTFE (polytetrafluoroethylene) but is instead a polyimide. The first FR-4 circuit boards used glass cloths impregnated with resin. Since the glass cloths used to make FR-4 are product quartz, it has some conductivity properties. Later on, the epoxy glass replaced the glass cloth, which further increased the conductivity of FR-4 circuit boards.
The high dielectric constant value of FR-4 allows it to conduct signals at high frequencies. After the replacement of glass cloths with epoxy glass, they created the FR-4 TG circuit board. It has a much higher temperature rating than that of other FR-4 circuit boards due to its anisotropy.
What are the different types of FR4 tg?
We can classify FR4 tg by material thickness, type of substrate, or construction methods. There are two main FR4 tg on the market that we commonly use in semiconductor processing: high-density polyethylene (HDPE) and Metal-coated Polyimide (MPI).
HDPE FR4 tg is the most popular type of FR4 tg in the industry. It has a thicker film than MPI FR4 tg, making it more resistant to wear and tear. However, because it is thicker, HDPE FR4 tg takes longer to dry than MPI FR4.
MPI fr4 has superior thermal properties to HDPE FR4. Because MPI fr4 is thinner than HDPE fr4, it is easier to laminate and dry faster than HDPE FR4. However, it is more susceptible to wear and tear than HDPE FR4.
FR-4 TG Construction:
We can construct the substrate of FR-4 TG can by two methods. Thermoplastic Substrate/Thermoset Substrate and Laminated Layer/Thermoset Layer.
- Thermoplastic Substrate/Thermoset Substrate Method
The substrate of this method is a thermoset that can be thermally cured, for example, epoxy resin. Bonding layers construct the laminate. We call it top and bottom films of FR-4 TG to the substrate by chemical or physical vapor deposition (CVD) or solvent casting (SNC).
- Laminated Layer/Thermoset Layer Method
The use of adhesive or welding forms laminated layers of the laminate.

FR-4 TG is an abbreviation for FR-4 Thermoset. It is the generic name for Polyimide printed circuit board material. The Tg of FR-4 TG is between 190°C and 210°C, making it suitable for high-temperature applications. FR-4 TG provides space to deliver high power signals with minimal impedance. It makes it ideal for fast, low impedance power transmission lines.
Tg is a property that helps us to understand the thermal properties of a material. The Tg changes as the temperature changes for any given material. Circuit board material makers should consider this information when choosing boards. You should avoid High tg PCB in applications where you expect high temperatures because they will not tolerate high temperatures and low Tg PCBs. FR4 High TG circuit boards are also known as high-temperature board insulation materials.
What is the difference between G10 and FR4?
FR-4 and G10 are both Polyimide materials. But we make FR-4 using two different methods, making it suitable for different applications. The advantage of FR-4 TG (FR4 TG) over the other FR-4 material is that it is thinner. It also has a high dielectric strength by construction. This makes it possible to get rid of the anisotropy during manufacture and transport. FR4 TG circuit boards are helpful in high-speed digital circuits.
High TG PCB
When considering the temperature of the circuit layers, the electrical connections fail more at high temperatures. The high temperature also causes damage to electronic circuits. Especially in industrial applications, people must take care of the time of delivery, which means that it is often more important to consider the time until failure than reliability. It is essential that you go to reliable companies such as RayMing PCB and Assembly to ensure that you get expert services to your satisfaction.
High-Temperature PCB (HT PCB)
A high polymer module (semiconductor) causes more heat that causes damage to electronics. It also causes heating up of various FPGA chips.
FR-4 TG PCB is useful in circuit boards designed for high-speed digital circuits. The FR-4 TG PCBs are anisotropic with a dielectric constant between 4.7 and 5.2. This means they transmit signals better than other circuit boards at high frequencies. Because the FR-4 TG PCB is a thermoset, its temperature stability is essential to its performance.
We can achieve the best performance of FR-4 TG PCB when we operate it at temperatures between -40°C and 125°C. If the circuit board operates outside of this temperature range, we should design for these temperatures. The FR-4 TG circuit board has a lower impedance than other types of FR-4 due to its high dielectric constant (k). When designing boards for high-speed digital circuitry, the FR-4 TG circuit board gives faster edge rates and faster rise times. It improves reliability because it drops less voltage.
FR-4 TG circuit boards can help designers meet their functional and reliability requirements. It is why they are best in high-speed digital circuit design.

Essentials for High-Temperature PCB
Materials used to make FR-4 TG circuit boards include copper, nickel, and gold. The copper is best as the signal conductor and the circuit board material we choose based on the transmission frequency. Gold is one of the best materials for high-frequency transmission due to its low resistivity. We can efficiently manufacture FR-4 TG circuit boards by the thermoset injection molding (TIM) method.

The use of FR-4 TG circuit boards in automotive or medical applications is high. Because they are suitable for cleaning flammable chemicals, it is easy to get rid of any dust and dirt because they are resistant to heat due to their use in these environments.
Circuit boards with FR-4 TG properties are useful in electronic devices that operate at high temperatures. High temperatures cause problems with the electrical connection of the circuit board and can lead to failures in the device.

FR-4 TG, FR-4, G10, G11 boards are all polyimide-based materials. The material comes from two glass cloth sheets, first impregnated with wax and then coated with a gummy substance called resin. We heat the first layer to 65°C and the second layer to 250°C. Place the two layers together and put on a hot plate at 400°C. The resin melts, and the glass sticks together and forms one solid plate.
FR-4 TG circuit board is an anisotropic circuit board made on a thermoset, which means it does not require any additional etching process. The anisotropy of the FR-4 TG circuit board consists of two technical characteristics, low impedance, and high k value. Also, the impedance is lower due to the high dielectric constant in the board. The low impedance of the FR-4 TG circuit board allows it to transmit high frequencies.
You will find that the k value of polyimide circuit boards is quite high. The higher the value, the more capacitance in a particular length. If two FR-4 TG circuit board lengths with different k values, they will appear as one length with great capacitance. It is ideal for transmission at low frequencies.

The higher the frequency, the higher the dielectric constant required to transmit the frequencies. FR-4 TG circuit board has a slightly lower dielectric constant than FR4. But because its operating temperature is much lower, it will transmit lower frequencies. The FR-4 TG PCB circuit board has a k value of 4.4, higher than FR-4 circuit boards.
This type of FR-4 TG is similar to FR-4, but we make it with a lower dielectric material. High-temperature resistance of the material makes it suitable for use in high-temperature electronics.
