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.

Most Westerners know very little about Estonia. A former Soviet Bloc country, Estonia has come a long way since restoring its independence in 1991. Electronics companies are thriving in this tiny EU member country, and capital city Tallinn has been called “Silicon Valley on the Baltic Sea.” During productronica, I met with Arno Kolk, general manager of the Estonian Electronics Industries Association, and we discussed the explosion of new technology in this “Baltic Tiger” country?

EDA Technologies is a South African company that offers PCB design engineering services, mainly for the domestic electronics market, which makes up a surprising 12.5% of South Africa’s GDP. Barry Matties recently spoke to founder Nechan Naicker about the benefits of outsourcing to South Africa, the market segments they service there, and any advice he had to offer from his 20+ years in the industry.

I was recently given the opportunity to write an article for our publication. Being somewhat new to this industry, I figured it would be a good idea to write an introduction on how I got into electronics—specifically the part most people my age don’t give thought to.
