As operating frequencies continue to rise in AI servers, networking equipment, automotive radar, and high-speed communication systems, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) have become some of the biggest challenges in PCB development. Many engineers attempt to solve EMI issues after prototype testing, but by then, redesigns can be expensive and delay production schedules. A better approach is to integrate Design for Manufacturability (DFM) principles during the PCB design stage. Proper DFM doesn't just improve manufacturability—it also significantly enhances signal integrity, reduces electromagnetic emissions, and increases product reliability. In this article, we'll explore how DFM practices help solve EMI and EMC problems in high-frequency PCB designs.

The rapid growth of artificial intelligence (AI), machine learning, and high-performance computing is creating unprecedented demand for faster and more efficient memory technologies. For decades, DRAM (Dynamic Random Access Memory) has been the foundation of modern computing. However, as AI models become larger and require massive amounts of data processing, traditional DRAM is facing challenges in bandwidth and power efficiency. This has accelerated the adoption of HBM (High Bandwidth Memory) — a next-generation memory technology designed specifically for AI accelerators, GPUs, and advanced computing systems. Understanding the differences between DRAM and HBM is essential not only for semiconductor engineers but also for PCB designers and manufacturers involved in high-speed electronic systems.

In modern electronic systems, inductors are often overlooked because of their simple structure. However, they play a critical role in ensuring power stability, signal integrity, and electromagnetic compatibility in nearly every electronic device. From smartphones to high-performance computing systems, inductors are essential building blocks in power and RF circuit design.

Materials are quietly moving up again Nothing dramatic happened on June 30 in the PCB world, but if you’re actually in the supply chain, you can feel it pretty clearly: cost pressure is building again. Not panic-level, but enough that most quotes are starting to shift.

Recent developments across the global electronics manufacturing ecosystem indicate that the printed circuit board (PCB) industry is no longer operating in a traditional cyclical recovery phase.
