Essential PCB Layout Tips for Designing a Reliable Circuit Board

• Ensure proper spacing between traces to avoid short circuits during manufacturing.
• Achieve copper balance on both sides of the PCB for optimal performance.
• Minimize EMI by using closely spaced solid planar return paths for signal traces.

• Avoid 90-degree trace angles; opt for 45-degree angles for improved reliability.
• Widen power and ground traces to enhance current flow and reduce heat buildup.
• Utilize vias for heat dissipation and electrical connections between layers.
• Enhance EMI shielding and heat dissipation by using a solid copper layer for the power layer.
• Place the reference point on the same side as SMT components for accurate assembly.
• Use power planes to distribute power effectively across the PCB.
• Consider buried vias in dense designs for efficient use of space.
• Assign unique drill size symbols for different hole types to maintain clarity in design.
• Create a symmetrical stack by alternating signal and plane layers around the PCB centerline.
• Choose trace width that suits your manufacturer’s capabilities.
• Route critical signals along the shortest path with minimal vias.
• Connect test points to power and ground networks for easier testing.
• Avoid placing test points near tall components to simplify evaluation.
• Leave ample space between traces and mounting holes to prevent hazards.
• Adjust trace width proportionally to trace height to avoid erosion during manufacturing.
