TLX-9 PCB 20mil--What Are the Advantages of TLX-9 PCB Compared to Other Materials?

  • March 20. 2024


Introducing TLX-9 PCB 20mil, a high-performance composite material that revolutionizes the world of printed circuit boards. Taconic TLX PCB combines PTFE/woven glass laminates with meticulously controlled electrical and mechanical properties, providing engineers and designers with a versatile and reliable solution for their most demanding applications. In this product description, we will delve deep into the advantages of TLX-9 PCB compared to other materials, highlighting its exceptional properties, construction details, and typical applications.

TLX-9 PCB offers several advantages compared to other materials. Here are some key advantages:

1.Low Dielectric Constant:

TLX-9 PCB has a low dielectric constant with 2.5 at 10 GHz, which means it exhibits low signal loss and improved signal integrity. This is especially important for high-frequency applications where maintaining signal integrity is critical.

2.Low Dissipation Factor:

TLX-9 PCB has a low dissipation factor with 0.0019 at 10 GHz, indicating minimal power loss. This helps in preserving the quality and efficiency of signals transmitted through the PCB.

3.Low Moisture Absorption:

TLX-9 PCB has a low moisture absorption rate of <0.02%, which makes it more stable and less prone to changes in electrical properties due to humidity. This characteristic ensures reliable performance in various environmental conditions.

4.High Dielectric Breakdown:

TLX-9 PCB exhibits a high dielectric breakdown strength of>60 kV, indicating its ability to withstand high voltages without electrical breakdown. This makes it suitable for applications that require high voltage operation.

5.Good Peel Strength:

TLX-9 PCB provides good peel strength of12 lbs./linear in., ensuring strong adhesion between the copper layers and the substrate. This contributes to the overall mechanical durability and reliability of the PCB.

6.Controlled Coefficient of Thermal Expansion (CTE):

TLX-9 PCB has a controlled CTE, meaning it expands and contracts at a predictable rate with temperature changes. This property helps to minimize stress and the risk of component failure due to thermal expansion mismatch.

7.High Flexural Strength:

TLX-9 PCB exhibits high flexural strength of 9-12 ppm/°C in X-Y CTE and  130-145 ppm/°C, both lengthwise and crosswise. This helps to prevent bending or warping of the PCB, ensuring its structural integrity and reliability.

8.Excellent Thermal Conductivity:

TLX-9 PCB has good thermal conductivity with0.19 W/m/K, allowing for efficient dissipation of heat generated by components on the board. This helps to maintain optimal operating temperatures and prolongs the lifespan of the PCB and its components.

Overall, TLX-9 Taconic RF PCB circuit board boardoffers a combination of electrical, mechanical, and thermal properties that make it suitable for a wide range of applications, especially those requiring high-frequency performance, reliability, and stability.
