Modern consumers are more enthusiastic about pursuing and accepting new technologies than ever before. As devices such as smartphones, smart watches, tablets and wearable fitness bracelets are updated, their performance expectations for each new generation of new products will also increase. They not only demand enhanced functions, but also expect devices to become smaller, faster, and run longer than previous generation products.
Although this strong desire for the latest products promotes the business development of technology companies, it also poses challenges to the engineers responsible for new designs. In order to create high-density circuits and increase runtime, efficiency must also increase. However, as the electronic components in the design become more compact and densely packed, it becomes more and more important not to cut corners on electromagnetic interference (EMI) related issues.
