Key Features of WL-CT338 for PCB Manufacturing

1. Superior Dielectric Performance

High-frequency applications demand materials that provide consistent and stable electrical properties. WL-CT338 excels in this domain:

• Dielectric Constant (Dk): WL-CT338 maintains a stable Dk of 3.38 ± 0.05, ensuring excellent frequency stability over a wide range of 0.5 GHz to 25 GHz. This stability is crucial for reducing signal distortion and ensuring predictable circuit behavior in RF and microwave designs.
• Dissipation Factor (Df): The ultra-low Df of 0.0029 minimizes energy loss during high-frequency signal transmission, making WL-CT338 ideal for applications where signal clarity is paramount, such as phased array antennas and radar systems.

2. Exceptional Thermal Properties

WL-CT338 is designed to withstand harsh thermal environments, ensuring long-term reliability in high-power applications:

• High Glass Transition Temperature (TG): With a TG exceeding 280°C, WL-CT338 maintains dimensional stability and electrical performance even under extreme heat conditions, such as those experienced in power amplifiers and satellite communication systems.
• Low Thermal Expansion Coefficient (CTE):
  • X/Y Direction: Matches copper foil with a CTE range of 11–18 ppm/°C, minimizing the risk of delamination between layers during thermal cycling.
  • Z Direction: Offers minimal expansion of 31–50 ppm/°C, ensuring plated through-holes (PTH) remain reliable and mechanically stable.

3. Processing Advantages

One of the standout features of WL-CT338 is its compatibility with existing PCB manufacturing processes:

• FR4-Like Processability: Unlike PTFE materials, which require specialized handling, WL-CT338 can be processed using standard FR4 manufacturing techniques. This simplifies fabrication, reduces production costs, and accelerates time-to-market for advanced designs.
• Advanced Machinability:
  WL-CT338 exhibits excellent machinability for fine lines, dense vias, and multilayer PCBs, making it suitable for compact, high-density circuit designs.

4. Moisture Resistance and Thermal Conductivity

High-frequency PCBs often operate in environments exposed to humidity or extreme temperatures. WL-CT338 addresses these challenges with:

• Low Water Absorption: With absorption rates as low as 0.02%–0.15%, WL-CT338 maintains its dielectric properties and structural integrity in humid conditions, making it ideal for outdoor telecommunications and automotive radar systems.
• High Thermal Conductivity: Ranging from 0.41 to 0.72 W/mK, WL-CT338 efficiently dissipates heat, supporting high-power applications such as amplifiers, power modules, and RF components.

Why WL-CT338 Materials Are Ideal for PCB Manufacturing

1. Consistent Performance at High Frequencies
WL-CT338 materials are known for their ability to maintain a stable dielectric constant (Dk) of 3.38 ± 0.05 and an ultra-low dissipation factor (Df) of 0.0029. These properties ensure minimal signal loss and reliable frequency performance in applications operating between 0.5 GHz to 25 GHz, making it ideal for advanced RF and microwave circuit designs. This stability is crucial for telecommunications, satellite communication, and radar systems.

2. Exceptional Thermal Stability and Durability
WL-CT338 features a high glass transition temperature (TG) of over 280°C, ensuring dimensional stability and durability in high-temperature environments. Its low coefficient of thermal expansion (CTE) prevents delamination and ensures reliable plated through-holes (PTH) in multilayer PCBs, even during rapid thermal cycles. This makes WL-CT338 an excellent choice for aerospace electronics, automotive radar systems, and other thermally demanding applications.

3. Manufacturing Efficiency and Versatility
Unlike PTFE laminates, WL-CT338 is compatible with FR4-like PCB manufacturing processes, simplifying fabrication and reducing production costs. Its advanced machinability supports dense circuit layouts and fine line designs, enabling manufacturers to produce compact, high-performance PCBs efficiently. These features ensure smooth scalability for both small-batch prototypes and high-volume production.

4. Reliability in Challenging Environments
The material’s low water absorption (0.02%–0.15%) and resistance to environmental stress ensure consistent performance in humid, high-radiation, and vacuum conditions. WL-CT338 is highly suitable for outdoor base stations, marine systems, and industrial IoT devices, where long-term reliability is critical. Its durable properties minimize maintenance requirements, reducing overall operational costs for mission-critical applications.
