In today’s fast-paced technological landscape, machine learning and artificial intelligence (AI) have emerged as transformative forces across various industries. These intelligent systems rely on advanced hardware and software to process vast amounts of data and make accurate predictions or decisions. While much attention is often given to the software algorithms powering these applications, the hardware component plays an equally crucial role. Customized printed circuit board (PCB) design tailored specifically for machine learning and AI applications is essential for optimizing performance, scalability, and efficiency. This article explores the significance of custom PCB design in building intelligent systems and the key considerations involved.
