Low‑loss Arlon PCB for high‑speed signal transmission

Arlon is a well-regarded manufacturer of high-performance, high-reliability specialty copper-clad laminates (CCL). Its products are widely used in demanding electronic applications within aerospace, defense, high-speed/high-frequency, and harsh environment industries.

Material Series and Characteristics

Arlon offers several material series, each targeting specific application needs:

◈ 1.High-Frequency/High-Speed Materials (RF/Microwave)
This is Arlon's most renowned area. Its materials feature very low dielectric constant (Dk) and dissipation factor (Df), enabling high signal transmission efficiency with low distortion.
Representative Products:
● AD Series (e.g., AD250C, AD300C): Ceramic-filled PTFE composites. They offer stable dielectric constants and good mechanical properties, widely used in aerospace and defense for phased array radars and satellite communications.
● CuClad Series: PTFE-based materials offering a range of dielectric constants for demanding microwave circuits.
Applications: Radar systems, satellite communications, point-to-point radios, 5G infrastructure, automotive collision avoidance radar.

◈ 2. High-Temperature, High-Reliability Materials
These materials can operate continuously at temperatures far exceeding standard FR-4 and offer excellent long-term thermal stability.
Representative Products:
● 85N Series: Modified epoxy/ceramic materials with a glass transition temperature (Tg) as high as 250°C and thermal decomposition temperature over 400°C. This is one of Arlon's flagship products, renowned for its exceptional thermal reliability and processability.
● 25N/25FR Series: Polyimide-based materials designed for high-reliability multilayer boards in harsh environments, offering high temperature resistance and chemical resistance.
Applications: Aircraft engine controllers, downhole oil drilling electronics, automotive under-hood control modules, high-power power supplies.

◈ 3. Metal-Clad/Thermal Management Materials
Designed specifically for power electronics and LED applications requiring efficient heat dissipation.
Representative Products: Thermal Clad series, which bonds an electrically insulating but thermally conductive dielectric layer to an aluminum substrate.
Applications: High-power LED lighting, automotive power converters, motor drives, power modules.

◈ 4. Halogen-Free/Flame Retardant Materials
Meet environmental and safety regulatory requirements.
Representative Products: E-glass reinforced modified epoxy resins, etc., compliant with UL94 V-0 flame retardancy and halogen-free.
Applications: Electronics for rail transportation and aerospace requiring RoHS compliance and strict flame retardancy.
