Optimizing PCB Layout for Enhanced Performance

• Ensure complete isolation between AC input and DC output for improved safety.
• Maintain a minimum distance of 5 mm between input and output terminals.
• Differentiate layout for control circuit and main power circuit for clarity.
• Avoid running high current/voltage wires parallel to measurement/control lines.
• Maximize copper utilization on PCB for efficient conductivity.
• Minimize long-distance wire connections for high current/voltage applications to reduce interference.
• Consider multi-layer boards with dedicated power/ground layers to reduce EMC effects.
• Utilize large copper areas in the work area to combat interference.
• Avoid noticeable loops in shielding ground wiring to prevent interference.

Enhancing Ground Wire Design

• Choose a suitable combination of single-point and multi-point grounding.
• Isolate digital circuits from analog circuits for optimal performance.
• Utilize the thickest feasible ground wire for better conductivity.
• Form the ground wire into a closed loop to minimize interference.

Effective Electromagnetic Compatibility Design

• Select appropriate wire width to enhance signal transmission.
• Implement a suitable wiring strategy to minimize interference.
• Consider a grid-pattern wiring structure to reduce wire inductance and crosstalk.
• Avoid long-distance equal routing to mitigate crosstalk and interference.
• Maximize spacing between wires and insert grounded traces between signal lines to reduce crosstalk.

Decoupling Capacitor Configuration for Noise Suppression

In DC power supply circuits, load variations can introduce noise. Strategic placement of decoupling capacitors helps suppress noise from load changes, ensuring reliable PCB design.
