Frequently Asked Questions

Thermal Dissipation PCBs

• Why is thermal management important in PCB design?


  Excessive heat can damage components, reduce signal integrity, and shorten product lifespan. Effective thermal management ensures stable performance, reliability, and long-term durability.

• What materials are best for thermal performance?


  High-conductivity dielectrics such as PTFE, ceramic-filled laminates, and specialized resin systems outperform standard FR-4 by conducting heat away from critical components.

• How do thermal vias improve heat dissipation?


  Thermal vias transfer heat vertically through the board into copper planes or heat sinks, significantly lowering component temperatures and spreading heat more evenly.

• What is copper coin technology?


  Copper coins are embedded or bonded inserts that act as localized heat sinks under hot components, providing highly efficient thermal transfer without increasing board thickness.

• How does Summit support customers with thermal management?

  Summit partners with engineers early in design, recommending materials, via structures, and heat-sinking strategies to ensure manufacturable, reliable, and cost-effective thermal solutions.
