- Topology and Timing Requirements:
Meeting the timing requirements is crucial for the normal and stable operation of the system. This is reflected in the PCB design through equal-length control of the traces. Understanding the timing requirements behind the equal length is essential for PCB design engineers. - Cabling Requirements for Power and Power Signals:
Effective filtering after protection should be prioritized in the power inlet circuit. Chip pins and filter capacitors should be kept as short and thick as possible for optimal performance. To minimize installation inductance caused by wiring, the energy storage capacitor should be placed strategically. Safety requirements dictate that voltage differences in the power network should be kept apart, and high-voltage network plug-in pins and vias should be hollowed out. - Thermal Considerations in Routing:
Considering the increasing power consumption and voltage drop in electronic design, the importance of PCB wiring in thermal design cannot be overlooked. Relevant electrical and thermal simulation tools should be used when necessary to assist in thermal design. It is vital to calculate the wiring channel strictly to meet current carrying requirements and pay attention to the current-carrying capacity of vias. Additionally, proper planning of the number and location of vias is essential. Heat dissipation issues can be addressed by adding copper to the ground in a large area under high-heat-generating chips and by strategically adding ground holes to enhance heat dissipation. Avoid running high-speed and sensitive signal lines in all layers in the projection area of high-power, heat-generating devices. Strengthening the wiring channel for long wiring paths of high-current power supplies can help reduce heat loss. Moreover, for heat-dissipating devices with added heat-dissipating pads, vias should be added to enhance heat dissipation.
In summary, PCB wiring is a complex, systematic project that requires design engineers to possess comprehensive knowledge across multiple disciplines and strong analysis and processing capabilities in order to achieve a good balance in all aspects of integration.
