Reading time ( words)
Many aspects of a PCB’s performance are determined during detailed design, e.g., making a trace a specific length for timing reasons. Timing issues are also affected by temperature differences between components. Thermal issues with the PCB design are largely locked in during the component (i.e., chip package) selection and layout phases.
After this point only remedial actions are possible if components are found to run too hot. We advocate a top-down approach starting at the system or enclosure level in order to understand the flow environment for the electronics, which is critical for air-cooled electronics. Assumptions made about the uniformity of the airflow in early design that subsequently proves unachievable can have a disastrous impact on the commercial viability of the product and meeting the market window.
This handy “how to” guide provides an overview of the key considerations in PCB thermal design and how to optimize the thermal layout.

Electronics companies are always under great pressure to continually grow and innovate. In addition to navigating ever-accelerating design cycles, they must also address and overcome generational complexities associated with their products, the underlying components they use, and the human capital accountable for delivering on time and on budget. Electronics firms can ill afford the time and resource inefficiencies associated with manually correcting design errors, poor library data integrity, or other inconsistencies leading to missed deadlines or even costly re-spins.

Hard to believe that a year ago, I was getting ready to attend DesignCon and IPC APEX EXPO and wondering if this Novel Coronavirus was going to cut into attendance from the Pacific Rim. Now, we’re accustomed to virtual trade shows. They’re not ideal, but they’re the best we can do while meeting in person is not possible. We’ve learned to adapt.
