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.

During the last week in April, the 26th Interconnection Techniques in Electronics (TIE) show was held at the Gheorghe Asachi Technical University in Iasi, Romaina, a wonderful hill town not unlike Rome. The event, a convention for the Romanian electronic packaging community, included a series of actions designed to draw smart young students to the electronics industry, which is clearly growing. Participants had only four hours to create this PCB design, which was generated by a team of professionals from Continental Automotive Romania Timisoara.

Throughout my decades-long career in PCB design, I have been fortunate. I’ve only had to search for a job out of desperation once. I had no idea my IPC Certified Interconnect Designer credentials would come in handy when I hit the pavement. It also helped that I am known to "work well on a team." It turns out that being able to play well with others is a real plus in the PCB design community.

Speaker John Stine, VP of operations at Summit Interconnect’s Anaheim facility, gave a presentation on flex and rigid-flex design and fabrication. At least 75 electronics professionals listened as Stine, an expert in flex and rigid-flex technologies, discussed proper trace geometries, grounding, cover lay, adhesives, signal integrity, impedance control, book-bindings and much more in his 80-minute presentation.
