Fr4 tg 170 board is one kind of High Tg PCB.
High-Tg PCBs refer to circuit board materials with a relatively high glass transition temperature (Tg), typically above 170°C.
High-Tg materials offer excellent heat resistance, moisture resistance, chemical resistance, and dimensional stability.
Specification:
Shengyi FR4 Series – A mainstream choice that includes models such as S1170G (Tg 180°C) and S1000-2M (Tg 170°C), offering high heat resistance and excellent dimensional stability.
IT-8300GA – A high-Tg circuit board material with a glass transition temperature of 200°C, designed for 5G base stations, millimeter-wave antennas, and other RF (radio frequency) applications. It features a dielectric constant (Dk) of 3.0 and an extremely low loss factor (Df) of 0.0020.
Features:
1, High Thermal Conductivity
High-Tg circuit boards offer superior thermal conductivity, enabling more effective heat dissipation. This helps enhance the stability and reliability of electronic devices during operation.
2, Outstanding Mechanical Properties
With their high strength and rigidity, High-Tg circuit boards can withstand significant mechanical stress. They maintain stable performance even under harsh environmental conditions, making them ideal for military and aerospace applications.
3,Excellent Electrical Performance
High-Tg materials feature a low dielectric constant and low loss tangent, which improve signal transmission quality and electromagnetic compatibility (EMC). These properties make them particularly suitable for high-frequency and high-speed signal transmission applications.
4, High-Temperature Stability
High-Tg circuit boards maintain excellent performance and stability in high-temperature environments, providing a critical advantage for electronic devices that must operate under extreme thermal conditions.
5,Cost-Effectiveness
Compared with other high-end circuit board materials, High-Tg PCBs offer lower production costs, making them an attractive choice for manufacturers seeking a balance between performance and budget in high-temperature applications.
6,Strong Processability
Composed of glass fiber and aromatic epoxy resin, High-Tg circuit board materials demonstrate excellent processability and reliability. They are less prone to delamination or resin separation during manufacturing and assembly.
Application:
The application fields of high Tg circuit boards mainly include the following aspects:
1. Multilayer Printed Circuit Boards (MLBs)
High-Tg circuit boards are widely used in multilayer printed circuit boards, especially those with more than 10 layers. High-Tg materials - particularly Rogers 4350B PCBs - offer excellent heat resistance, moisture resistance, and dimensional stability, ensuring reliable performance in complex wiring and high-temperature environments.
2. Automotive Electronics
In the automotive industry, High-Tg circuit boards are used to manufacture high-performance electronic control systems. Vehicles generate substantial heat during operation, and High-Tg PCBs can withstand elevated temperatures, ensuring circuit stability and long-term reliability.
3. 5G Communication Base Stations
Equipment used in 5G communication base stations must operate continuously under high heat loads. High-Tg circuit boards - especially high-frequency boards - maintain signal integrity and communication efficiency by resisting thermal deformation and degradation in high-temperature environments.
4. Aerospace Equipment
Aerospace systems demand exceptional heat resistance and stability from their circuit boards. High-Tg PCBs can endure extreme temperature variations, ensuring the safe and reliable operation of critical aerospace components.
5. Industrial Control and Precision Instruments
Industrial control systems and precision instruments impose strict requirements on circuit board thermal performance and stability. High-Tg materials provide consistent and reliable performance in complex and harsh environments, ensuring the accuracy and longevity of these instruments.
6. Routers and Network Devices
Network equipment such as routers often operates under high load conditions, generating significant heat. High-Tg circuit boards help maintain stable performance and signal reliability even in high-temperature environments, ensuring continuous and efficient communication.
Customized product:
Most of our products are customized based on the original Gerber files provided by our customers.
After receiving the original Gerber files, we convert them into working Gerber files for production use.
During this conversion process, we adjust certain parameters-such as hole diameter, trace width, and trace spacing-to optimize manufacturability and ensure smooth production.
Package and warranty:
All our products are vacuum-packaged with desiccant to ensure optimal protection during storage and transportation.
The shelf life of vacuum-packaged circuit boards varies depending on the surface treatment process, typically ranging from 3 to 12 months. The details are as follows:
Shelf Life for Different Surface Treatment Processes
ENIG (Electroless Nickel Immersion Gold):
Can be stored for up to 12 months under vacuum packaging with desiccant protection.
Lead-Free HASL (Hot Air Solder Leveling):
When no special storage adjustments are made, the shelf life is typically about 3 months.
OSP (Organic Solderability Preservative):
Has a shelf life of 3–6 months under vacuum packaging with desiccant protection. However, if stored improperly (e.g., without desiccant or with insufficient vacuum sealing), the shelf life may shorten to around 3 months.
Immersion Gold (Chemical Gold Plating):
Shelf life can reach 6–12 months, provided that sealed packaging and desiccant are used.
Certification:
We are committed to delivering high-quality products through the continuous improvement of our quality management system.
Our products are certified to meet international standards, including ISO 9001, ISO 14001, ISO 13485, IATF 16949:2016, SGS, and CE.
