Driven by Moore's Law, the electronics industry continues to develop products with ever-increasing functionality and integration.
Driven by Moore's Law, the electronics industry is witnessing ever-increasing functionality, higher integration levels, faster signal rates, and shorter product development cycles. As electronic products continue to become smaller, more precise, and faster, PCB design not only needs to accomplish the wiring connections among various components but also must address the myriad challenges posed by high speed and high density. PCB design will thus exhibit the following trends:
1. The R&D cycle is continuously shortening. PCB engineers need to adopt first-class EDA tools and software; they should strive for success on the first board, comprehensively considering all relevant factors and aiming for a single-pass success rate; multiple engineers should work in parallel, dividing tasks and collaborating effectively; modular reuse should be emphasized, and technical accumulation must be given high priority.
2. Signal rates are continuously increasing. PCB engineers need to acquire certain high-speed PCB design skills.
3. The board density is high. PCB engineers must stay abreast of industry trends, keep up with new materials and processes, and adopt first-class EDA software that can support high-density PCB design.
4. The operating voltage of logic gates is becoming increasingly lower. Engineers need to carefully design the power supply paths—not only to meet current-carrying capacity requirements but also to reduce power-ground impedance and minimize power-ground noise by appropriately adding decoupling capacitors and, if necessary, adopting a closely coupled approach with adjacent power and ground planes.
5. SI, PI, and EMI issues are becoming increasingly complex. Engineers need to possess basic skills in SI, PI, and EMI design for high-speed PCBs.
6. The use of new processes and new materials will promote the adoption of buried resistors and buried capacitors.
