Rogers PCB Material Handle Heat Dissipation
PCBs need to be able to dissipate heat from their components, so they can perform at optimal levels. Rogers PCB material handles this with high thermal conductivity and low outgassing, making it a good choice for many applications. However, it’s important to understand the environmental factors that play a role in this process to ensure your Rogers circuit boards meet your specific requirements.
For example, FR-4 isn’t ideal for space applications because it isn’t outgassing tolerant. In these environments, trapped gases can penetrate the surface of the laminates and degrade them. rogers pcb laminates are designed to reduce outgassing, which makes them an excellent choice for space-based applications. Another factor is the glass transition temperature, which is the point at which a material starts to expand and soften as it warms up. This is a common problem for PCBs, but Rogers materials have a lower glass transition temperature than traditional PCBs, which prevents them from softening and warping.
The low moisture absorption and coefficient of thermal expansion properties of Rogers PCB material also improve dimensional stability. This helps them retain their shape under different conditions, which is critical for high-frequency applications.
How Does Rogers PCB Material Handle Heat Dissipation?
In addition, the low outgassing and glass transition temperature of Rogers PCB materials help them withstand environmental changes and maintain their structural integrity. This enables them to be used in a wide range of industries, including aerospace and automotive applications. Rogers IsoClad laminates are especially well suited for these applications, as they have low dielectric constants and broad frequency ranges, enabling them to handle both RF and EMI signals.
As with other PCB materials, choosing the right Rogers laminate is a crucial step in the process of creating a high-performance circuit board. The right laminate has the right combination of dielectric constant, loss tangent, and thermal conductivity to meet your design requirements. It’s also important to account for the material’s coefficients of expansion and shrinkage.
After fabrication, the resulting circuit boards are tested to confirm their continuity, resistance, and performance matches specifications. These boards are then packaged and shipped to product manufacturers for assembly and integration into electronic systems.
Rogers FR-4, IPC 6012, and UL 94-0 certified laminates are all suitable for high-performance printed circuit boards. They are available in a variety of thicknesses and sizes, and they can be custom cut to order. However, they aren’t suitable for all projects. You’ll want to select a fabricator with extensive experience designing and fabricating PCBs made from this type of material. Twisted Traces, for example, offers PCBs fabricated from Rogers material, and they have over 30 years of experience.
For best results, choose a PCB material that passes various certifications and meets military and IPC standards. It should also have an UL 94-0 flammability rating and an IPC 6012 automotive specification. It should also have a low moisture absorption rate and low outgassing. It should also have a low glass transition temperature, and it should be able to pass a chemical process for panel and pattern processing.
