Main Principles of PCB Wiring
- Start by wiring the power line and ground line first to ensure optimal electrical performance.
- Preferably, widen the ground wire more than the power wire, and prioritize the order as ground wire > power wire > signal wire.
- For high-frequency lines, wire them first and keep input and output ends apart to avoid interference.
- Ground the oscillator housing, keep clock lines short, and avoid excessive wiring of the clock line.
- Utilize 45-degree polyline wiring to reduce high-frequency signal radiation and avoid 90-degree polylines.
- Avoid loops on signal lines, keep them short and thick, and add protective ground on both sides of key lines.
- For sensitive signals, use a “ground wire-signal-ground wire” approach when transmitting through flat cables.
- Reserve test points for key signals for easy production and maintenance testing.
- After schematic wiring, optimize the layout, fill unwiring areas with ground wire, and consider using multilayer boards for power supply and ground wires.
