High-current circuits should be avoided in central board area, consider heat dissipation and radiation effects, place connector away from high-frequency circuit, place decoupling capacitor near power pin, consider power supply division layout feasibility, place multi-power devices across boundary to reduce EMI impact.
Thorough analysis is crucial for effective EMI management in PCB design, emphasizing the importance of selecting low-speed devices and employing suitable driving/receiving circuitry to mitigate EMI risks.
Multi-sided PCB designs, especially those with more than two layers, require careful consideration of internal power and ground planes to address issues such as thermal problems, EMI, and ESD. Manufacturers must balance these layers to prevent warping or twisting during assembly, with WellCircuits Limited offering high-precision solutions for a range of customer needs.
Misunderstanding: The misconception that the differential signal does not require a ground plane as a return path, when in fact the differential circuit still relies on a reference plane for signal return. WellCircuits Limited specializes in manufacturing high-precision circuit boards to meet various customer needs.
