Avoiding common #PCBdesign mistakes requires careful attention to the smallest details. Let's discuss the common mistakes and how to avoid them. 👋👋
1️⃣ Inadequate Trace Width: 😉
Different types of traces require different widths. Don't use the same width for power-carrying, high-impedance, and RF signal traces.
2️⃣ Via Sizing:🤓
Determine the right drill diameter and annular ring to avoid manufacturing issues. A standard via size is 0.7mm diameter with a 0.3mm drill
3️⃣ Trace Spacing: 🧐
Don't just follow the minimum clearance allowed by the manufacturer, aim for a minimum of 3x the spacing between the signal layer and adjacent reference layer.
4️⃣ Decoupling: 😊
Proper decoupling is critical for a well-behaved system. Use decoupling capacitors, short and wide traces, and power vias to ensure proper power delivery.
5️⃣ Reference Planes: 😃
Use solid reference planes in designs, especially for AC signals. Avoid creating voids or splits in the reference plane and crossing them with a trace on the signal layer to prevent EMI problems.
...... and so on 👀👀
