What is the Taconic TLE-95 laminate?
TLE-95 laminates are specifically engineered to deliver optimal electrical and mechanical properties, fulfilling the stringent requirements of complex microwave and high speed digital applications. The Dk exhibits minimal change over temperature. TLE-95 is typically offered with a 2.95 DK ± 0.05. The low Z-axis coefficient of thermal expansion (CTE) ensures exceptional reliability for plated-through holes, while the low thermal expansion characteristics in the X and Y planes enhance reliability in surface mount applications.
TLE-95 laminates are dimensionally stable, exhibit virtually no moisture absorption during processing and are generally ordered clad on one or both sides with 0.5, 1 and 2 oz. electrodeposited copper.
TLE-95 laminates achieve a flammability rating of V-0, as tested and verified according to the standards specified in IPC-TM 650. Every shipment of TLE-95 laminates is accompanied by a certificate of compliance that includes comprehensive test data, thereby confirming their conformity to industry requirements.

Features of the Taconic TLE-95 laminate
Controlled Dimensional Stability
This property is crucial for maintaining the integrity of intricate circuits and components. TLE-95 laminate exhibits minimal warping, even under thermal and mechanical stresses. The material maintains structural integrity across diverse operating conditions, critical for precision components.
Low and Stable Dielectric Constant
The material’s consistent dielectric properties contribute to a predictable and stable electrical performance, which is essential for high speed and high frequency applications. A consistent Dk (2.95+/-0.05) across frequencies and temperatures guarantees predictable signal propagation, vital for RF and microwave designs.
Low Dissipation Factor
With a low dissipation factor, TLE-95 minimizes energy losses in high frequency applications, making it ideal for RF and microwave circuitry where signal integrity is paramount. A minimal loss tangent (typically 0.0026 at 10GHz frequencies) ensures efficient signal transmission, reducing energy loss in high frequency circuits.
Low CTE Value
With a low coefficient of thermal expansion (CTE), TLE-95 minimizes dimensional changes under temperature fluctuations, ensuring reliability in high-heat scenarios. A low coefficient of thermal expansion ensures that the material remains stable under temperature fluctuations, minimizing the risk of deformation and ensuring reliable performance in precision applications.
High Flexural Strength
TLE-95 laminate offers robust mechanical performance, providing high resistance to bending and mechanical stresses, which is key for the durability and longevity of electronic assemblies. Robust mechanical properties enable durability in rugged applications and multilayer PCB designs.
UL 94 V-0 Rating
Safety is a major concern in electronics. Achieving a UL 94 V-0 rating means that TLE-95 is highly flame retardant, reducing the risk of fire in critical applications. Superior flame resistance enhances safety in electronics, meeting stringent regulatory standards.
