Designing a perfect PCBA (Printed Circuit Board Assembly) requires consideration of many aspects, from circuit design to component selection, to production and testing. The following are some of the difficulties and key points in PCBA design and how to achieve a perfect design.

PCB design is a complex and delicate process, involving circuit schematic design, component layout, routing rules, power supply and grounding design, EMI/EMC design, manufacturing and assembly, etc. Each link requires the designer to consider it in detail in order to design a circuit board with excellent performance, stability and reliability. Through the summary of this article, I hope to provide some reference and guidance for PCB designers to improve the quality and efficiency of PCB design.
