What is the high-frequency TLY-5 laminate?
TLY-5 laminates are made from lightweight woven fiberglass, offering superior dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven structure of the TLY-5 material provides enhanced mechanical stability, making it well-suited for high-volume manufacturing. Its low dissipation factor ensures reliable performance in automotive radar applications operating at 77 GHz, as well as in other millimeter-wave frequency antenna designs.
Comparative OEM testing at 77 GHz of lightly reinforced TLY-5 vs. its closest chopped fiber reinforced competitor has shown “drop in”/equivalent insertion losses/dielectric properties. The primary benefit is much higher manufacturing yields. The dielectric constant range is 2.17 to 2.40. For most thicknesses, the dielectric constant can be specified anywhere within this range with a tolerance of +/- 0.02. In the low dielectric constant range, the dissipation factor is approximately 0.0009 at 10 GHz. Typical applications include satellite communications, automotive radar, filters, couplers, avionics and phased array antennas.
Features of high-frequency TLY-5 laminate for PCBs
Benefits of high-frequency TLY-5 laminate for PCBs
TLY-5 is a workhorse in the RF microwave substrate world where the fiberglass offers mechanical reinforcement. And this material meets UL 94 V-0 Rating.
Uniform, Consistent Dk and Lowest Df
The TLY-5 laminate is a specialized material that provides low and stable dielectric constant (Dk) values, as well as very low dissipation factor (DF). These properties are essential for applications in high-frequency electronic devices, where maintaining signal integrity is crucial. The low Dk ensures minimal signal loss and reduced crosstalk between adjacent layers, which enhances the overall performance of printed circuit boards (PCBs) and other electronic components.
High Peel Strength
The TLY-5 laminate is widely recognized for its high peel strength, which is a critical performance attribute, especially in applications requiring robust adhesion between layers or substrates. This characteristic ensures reliable bonding and durability in multilayer PCB designs and other advanced electronic assemblies. The high peel strength of TLY-5 minimizes the risk of delamination during manufacturing processes, as well as under challenging operational conditions, such as thermal cycling or mechanical stress. As a result, TLY-5 is an ideal choice for high-performance applications, particularly in environments where structural integrity and long-term reliability are paramount.
Dimensionally Stable
The TLY-5 laminate is characterized by its dimensional stability, which is a critical property for ensuring the reliability and performance of electronic components. Dimensional stability refers to the material’s ability to maintain its shape and size under varying environmental conditions, such as changes in temperature and humidity. This characteristic is particularly important in applications where precision and accuracy are paramount.
Laser Ablatable
The TLY-5 laminate is recognized for its laser ablatable properties, making it an excellent choice for precision manufacturing processes that require fine patterning or etching. Laser ablation allows for highly accurate and controlled removal of material, enabling the creation of intricate geometries without the need for chemical etching or traditional mechanical methods. This property makes TLY-5 particularly valuable in advanced applications such as the fabrication of high-frequency antennas, RF circuit boards, and other electronic components where precision and minimal material disruption are essential.
Low Moisture Absorption
The TLY-5 laminate is designed with advanced materials that provide a range of beneficial properties, one of which is its low moisture absorption capability. This characteristic ensures that the laminate remains stable and maintains its structural integrity even in environments with varying humidity levels. By minimizing moisture uptake, the TLY-5 laminate helps to prevent issues such as warping, swelling, or delamination that can occur in other materials when exposed to moisture over time. In summary, the TLY-5 laminate’s low moisture absorption not only enhances its reliability but also expands its usability across various industries and applications where material stability is critical.
Applications of high-frequency TLY-5 laminate for PCBs
TLY-5 is increasingly favored in industries like aerospace, automotive radar, and telecommunications, where advanced manufacturing techniques are needed to meet the stringent performance and reliability standards of next-generation electronic systems.
The TLY-5 laminate is made from lightweight woven fiberglass and is primarily used in aerospace applications. This composite material is known for its excellent strength-to-weight ratio, making it ideal for use in the design and construction of aircraft components. Its durability, thermal resistance, and corrosion resistance further enhance its suitability for demanding aerospace environments. The TLY-5 laminate is commonly utilized in the manufacturing of structural parts, interior components, and other critical systems where performance and weight efficiency are paramount.
Automotive Radar
The TLY-5 laminate is widely used in automotive radar applications, owing to its exceptional dielectric properties and high dimensional stability at millimeter-wave frequencies, particularly around the 77 GHz range used for radar systems. Automotive radar technology plays a crucial role in enabling advanced driver-assistance systems (ADAS), such as adaptive cruise control, collision avoidance, and autonomous driving capabilities. These radar systems require high-performance materials that can maintain signal integrity, support high-frequency operation, and withstand harsh environmental conditions over extended periods.
TLY-5’s low dissipation factor (approximately 0.0009 at 10 GHz) is key to ensuring minimal signal loss, which is critical in maintaining the accuracy and reliability of radar signals, particularly in complex automotive environments with high electromagnetic interference (EMI). The laminate’s high thermal and mechanical stability further ensures consistent performance in automotive systems, which must operate reliably under varying temperature fluctuations, vibrations, and other demanding conditions.
Satellite & Cellular Communications
The TLY-5 laminate is extensively used in satellite and cellular communications systems, where its advanced dielectric properties and mechanical stability make it an ideal material for high-performance applications. In both satellite and cellular communication systems, reliable signal transmission, low signal loss, and precise signal integrity are crucial for maintaining high-quality performance, especially as frequencies move into higher millimeter-wave bands, such as those used for 5G, satellite uplinks, and other high-frequency communication technologies.
Power Amplifiers
The TLY-5 laminate is widely used in the design and manufacture of power amplifiers (PAs), particularly in high-frequency applications such as satellite communications, automotive radar, and 5G wireless systems. Power amplifiers play a crucial role in boosting signal strength for transmission over long distances or through challenging media, and the materials used in their construction must meet demanding performance standards for signal integrity, thermal stability, and mechanical robustness. TLY-5’s unique combination of properties makes it an ideal choice for these critical components.
LNBs, LNAs, LNCs, Ka, E and W band Applications
The TLY-5 laminate is used in LNBs (Low Noise Block converters), LNAs (Low Noise Amplifiers), LNCs (Low Noise Converters), and for various Ka, E, and W band applications due to its excellent electrical properties, thermal stability, and lightweight characteristics. These features make it a highly suitable material for high-frequency and high-performance electronic components, particularly in satellite communication, radar systems, and wireless communication technologies.
It is avionics & aerospace grade very low DK base material, and the TLY-5 pcb materials technology enable higher circuit densities, improved signal speed and integrity, and enhanced reliability in PCBs.
