What is the TU-752 PCB Material?
TU-752/ TU-75P laminate / prepreg are made of high quality woven E-glass coated with the epoxy resin system, which provides the laminates with UV-block characteristic, and compatibility with automated optical inspection (AOI) process. These products are suitable for boards that need to survive severe thermal cycles, or to experience excessive assembly work. TU-752 laminates exhibit excellent CTE, superior chemical resistance thermal stability and anti-CAF resistance.
One of the standout features of TU-752 material is their UV-blocking characteristic, which is particularly important in applications where exposure to ultraviolet light could degrade the performance of the material or lead to premature failure. The UV resistance of the epoxy resin system helps to ensure that the laminate maintains its structural integrity and electrical properties over extended periods of time, even when exposed to harsh lighting or outdoor environments.
They are specifically engineered to meet the demanding requirements of applications where high thermal stability and durability are critical. These products are ideal for use in printed circuit boards and other electronic components that must endure severe thermal cycling or undergo extensive assembly work, both of which can place significant stress on materials.

The features of TU-752 PCB Material
High Tg characteristics
The high Tg of 180 °C (DSC) TU-752 PCB material which is known for its elevated glass transition temperature (Tg). so that it possesses enhanced mechanical properties at elevated temperatures compared to standard polymers.
Lead-Free Compatibility
TU-752 laminates are designed to perform reliably without the inclusion of lead, supporting sustainable manufacturing while maintaining the high standards required for advanced electronics. Fully compliant with RoHS and lead-free soldering requirements, TU-752 supports eco-friendly manufacturing without compromising thermal or mechanical stability.
Excellent Coefficient of Thermal Expansion (CTE)
TU-752 laminates exhibit an excellent Coefficient of Thermal Expansion (CTE), which makes them highly compatible with the thermal expansion characteristics of various electronic components. A CTE closely matched to copper (11-15 ppm/°C in the X/Y axis) minimizes stress during thermal cycling, preventing via cracking and ensuring long-term structural integrity.
Anti-CAF capability
The anti-CAF (Conductive Anodic Filament) capability of TU-752 laminates is another critical feature. CAF can cause electrical short circuits and board failures due to the migration of conductive filaments under certain conditions. TU-752’s resistance to CAF ensures that it performs reliably over time, even in harsh environments, making it a trusted choice for high-performance electronics and automotive systems.
Chemical and Thermal Resistance
TU-752 laminates offer superior chemical and thermal resistance, which makes them highly durable in extreme environments. Whether exposed to harsh chemicals or high temperatures, TU-752 maintains its structural and functional integrity, ensuring long-lasting performance in devices like automotive electronics, high-powered devices, and industrial equipment.
Fluorescence for AOI
The fluorescent properties of the material allow for better visibility during automated optical inspection, ensuring that any potential defects or irregularities are quickly detected. This capability improves the overall quality control process and reduces the likelihood of faulty boards reaching the end consumer.
UV-Blocking Optical Properties
TU-752 laminates also possess UV-blocking properties, which are important in preventing damage from ultraviolet radiation. Blocks harmful UV radiation, protecting sensitive components and preventing resin degradation in applications exposed to sunlight or UV-based processes.
High Interlayer Bonding Strength with Optimal Resin Flow
The high interlayer bonding strength of TU-752 ensures a strong, reliable bond between layers, contributing to the material’s structural integrity. The laminate’s optimum resin flow during manufacturing ensures uniform distribution of resin, further enhancing bonding and reducing the risk of defects such as delamination.
Low Moisture Absorption
TU-752 laminates are designed with low moisture absorption, which is crucial in maintaining the material’s performance over time. High moisture absorption can lead to swelling, warping, and degradation of the laminate, so minimizing moisture uptake helps ensure long-term stability and reliability, particularly in outdoor or automotive applications where environmental exposure is more intense.
