The Rogers RO4450F™ and RO4460G2™ Bondply materials are designed for use in multi-layer PCB constructions, particularly when paired with RO4000 series laminates. These materials are particularly suited for applications requiring high reliability and compatibility with lead-free soldering processes. The RO4450F™ bondply offers improved lateral flow capabilities, making it an excellent choice for designs with challenging fill requirements. On the other hand, the RO4460G2™ bondply provides a higher dielectric constant (Dk) of 6.15, which is beneficial for certain high-frequency applications while maintaining low z-axis expansion to ensure reliability of plated through-holes.

When designing a PCB stackup using these materials, consider the following guidelines:

• Ensure compatibility with other materials in the stackup, particularly if using RO4000 series laminates like RO4003C, RO4350B, among others.
• Account for the thermal properties of the bondply, especially the glass transition temperature (Tg) and the coefficient of thermal expansion (CTE), which are crucial for thermal management and reliability during the PCB's operational life.
• Utilize the materials in applications that benefit from their specific properties, such as backhaul radios, power amplifiers, and other communication systems where high-frequency performance and thermal reliability are critical.

Additionally, the RO4450F™ and RO4460G2™ materials are recognized for their flame retardant capabilities with a UL 94 V-0 rating and are compatible with sequential lamination processes, which is advantageous for complex multi-layer designs requiring multiple lamination cycles. This makes them suitable for advanced electronic applications where safety and performance are paramount.
