What is the high Tg TU-768 PCB material?
TU-768 / TU-768P laminate / prepreg materials are crafted from high-quality woven E-glass fibers that are impregnated with an advanced epoxy resin system. This specialized resin system not only enhances the mechanical properties of the laminate but also provides several key performance benefits.
One of the standout feature of TU-768/TU-768P materials 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 (PCBs) and other electronic components that must endure severe thermal cycling or undergo extensive assembly work, both of which can place significant stress on materials.
Due to these outstanding attributes—thermal cycling resistance, low CTE, chemical resistance, thermal stability,and CAF resistance—TU-768 and TU-768P laminates are ideal choices for demanding applications such as automotive electronics, telecommunications, industrial control systems, and other high-reliability sectors where the durability of the PCB is critical to the overall performance and longevity of the product.
The features of high Tg TU-768 PCB material.
High Tg characteristics
The high Tg of 180 °C (DSC) TU-768 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.
High Thermal Reliability
The TU-768 PCB material is classified as high thermal reliability due to its exceptional performance and specific characteristics. This material is renowned for its ability to withstand extreme temperature variations and maintain its structural integrity and electrical conductivity. It has been rigorously tested and evaluated under various thermal stress conditions, consistently demonstrating outstanding stability and reliability. The unique composition and manufacturing process of the TU-768 PCB material contribute to its superior thermal performance, making it an ideal choice for applications where high thermal reliability is a critical requirement.
Excellent moisture resistance
The TU-768 PCB material is known for its excellent moisture resistance, which makes it an ideal choice for various applications in environments where humidity and moisture exposure are prevalent.This characteristic ensures that the integrity of the printed circuit board is maintained over time,reducing the risk of corrosion and other forms of degradation that can occur when materials are exposed to damp conditions.
Lead free processing compatible
Materials meet lead-free assembly requirements and meet RoHS standards. The TU-768 PCB material works fine with lead-free laminate materials. This makes them much safer when using them. This also means that you will make use of the TU-768 PCB material without having to worry about environmental pollution or hazardous substances.
Anti-CAF capability
This is another great property of TU-768 PCB material, this PCB laminate is CAF resistant. Conductive anodic filament (CAF) causes failures in PCB’s, and TU-768 PCB material is resistant to CAF and prevents failure in circuit board. The risk of CAF occurs when a metallic filament is formed from an electrochemical migration process.
