What is the high temperature TU-900 Tg260 laminate?
TU-900 Tg260 material is made of BT-like high performance resin system and E-glass fabric. This halogen-free material is engineered to possess both high elastic modulus and high reliability, as well as low Dk/Df characteristics for minimal electrical loss. The TU-900 laminate and TU-900P prepreg are specifically designed for high reliability multilayer substrates, SiP, radio frequency, and ultra-thin HDI board applications. These materials are ideal for boards requiring stringent X-Y dimensional stability, minimal board distortion, and the ability to withstand harsh environmental conditions.
This material is provide superior protection against moisture absorption, ensuring stable electrical properties even in humid environments. Complies with strict environmental regulations, promoting safer disposal and recycling practices. Additionally, TU-900 materials exhibit superior chemical resistance, high rigidity, low thermal expansion, and excellent long term reliability and CAF performance.
Features of the high temperature TU-900 datasheet
TU-900 Tg260 laminate is a high performance material designed for advanced applications, particularly where high reliability and thermal stability are paramount. This material is characterized by several key features that make it highly suitable for use in challenging environments.
Ultra High Tg Characteristics
One of the standout features of TU-900 Tg260 laminate is its ultra-high glass transition temperature (Tg) of 260°C. This elevated Tg makes it ideal for use in applications requiring enhanced thermal stability and long term durability under high temperature conditions. It ensures that the material maintains its mechanical properties even when exposed to extreme temperatures, making it a reliable choice for demanding applications.
Low-Loss Category Material
TU-900 is classified as a low-loss material, which means it has minimal signal attenuation and energy dissipation during electrical signal transmission. This makes it especially valuable in high frequency and high speed applications, where signal integrity is crucial for optimal performance.
Low Coefficient of Thermal Expansion (CTE)
The laminate’s low coefficient of thermal expansion (CTE) ensures that the material expands and contracts minimally when subjected to temperature fluctuations. This reduces the risk of material failure due to thermal stress, making it suitable for applications in which thermal cycling is a concern.
Halogen-Free and Antimony and Red Phosphorous-Free
TU-900 Tg260 is halogen-free and does not contain antimony or red phosphorous. This makes the material environmentally friendly, ensuring that it does not release harmful substances in the event of a fire, thereby meeting stringent environmental and safety standards.
Anti-CAF Capability
The laminate exhibits excellent anti-CAF resistance. This property prevents the formation of conductive filaments that could lead to short circuits or failures in electronic systems. This makes TU-900 Tg260 a preferred choice for high reliability applications, particularly in the electronics industry.
Excellent Moisture Resistance
TU-900 laminate also excels in moisture resistance, preventing degradation in humid or wet conditions. This makes it ideal for use in environments where exposure to moisture is inevitable, such as outdoor or marine applications.
Applications of the high temperature TU-900 Tg260 laminate
TU-900 Tg260 laminate’s unique combination of properties makes it suitable for a wide range of applications, particularly in fields that demand exceptional performance and reliability under extreme conditions.
Substrate
Ideal for printed circuit boards requiring high thermal stability and mechanical strength. These designs require materials that can withstand high temperatures, maintain signal integrity, and remain stable under harsh conditions.
HDI & ELIC Design
Suitable for high density interconnect (HDI) and extremely low inductance circuits (ELIC) designs, where miniaturization and performance are critical. The high thermal stability, low-loss properties, and excellent moisture resistance of TU-900 make it an ideal substrate for HDI and ELIC designs.
Aerospace & Military – Harsh Environments
The laminate’s low-loss and anti-CAF capabilities make it a solid choice for use in the consumer electronics industry, where devices need to function reliably in a variety of conditions. Essential for aerospace and military applications that demand exceptional durability and reliability in extreme conditions, such as high altitudes, harsh weather, and thermal cycling.
Advantages of the high temperature TU-900 Tg260 laminate
TU-900 Tg260 laminate not only offers outstanding performance in application but also provides several key advantages when it comes to processing.
Maximum Operating Temperature: 150°C
TU-900 laminate can operate at a maximum temperature of 150°C, making it compatible with high temperature applications that require consistent performance without degradation. This allows manufacturers to use the material in systems that experience long term elevated temperatures.
Lead-Free Processing Compatibility
With the industry’s push for environmentally friendly solutions, TU-900 Tg260 laminate is fully compatible with lead-free processing technologies. This ensures that it can be used in the production of electronic components that meet environmental standards, such as RoHS and other sustainability regulations.
Excellent Electrical Properties
The laminate boasts excellent electrical properties, such as low dielectric constant and low dissipation factor, which are essential for high frequency signal applications. These properties ensure that electrical signals are transmitted with minimal interference, making TU-900 ideal for high performance circuits.
Environmental Friendliness
As mentioned, TU-900 is halogen-free, antimony-free, and red phosphorous-free, which makes it an environmentally friendly material that aligns with the growing trend toward sustainability in electronic manufacturing. By eliminating harmful substances, it ensures the health and safety of both users and manufacturers.
Conclusion
