This comprehensive process guide will take you from start to finish:
Step 1: Prepare Your Design Environment
Before you begin, ensure your EasyEDA account is set up and you have familiarized yourself with the interface. If new to EasyEDA, consider running through basic tutorials to understand the tools and features available.
Key Considerations:
- Workspace Setup: Optimize your workspace for ease of access to tools and visibility.
- Component Libraries: Ensure access to EasyEDA’s comprehensive library for high-voltage components.
Step 2: Start with the Schematic
The first step in placing 120V power is to create a schematic that accurately represents your circuit.
Actions to Take:
- Component Placement: Add all necessary components that will operate at 120V, including switches, connectors, and other passive elements.
- Power Source Indication: Clearly indicate where the 120V power supply will connect to your circuit. Use the power symbol and label it accordingly to avoid confusion.
Step 3: Select Appropriate Components
Selecting the right components capable of handling 120V is crucial for safety and circuit performance.
Important Selection Criteria:
- Voltage Ratings: Ensure that all components can handle at least 120V.
- Certification: Prefer components that are certified for safety at high voltages.
- Thermal Management: Consider heat dissipation needs, as high-voltage components may generate more heat.
Step 4: Design the PCB Layout
Transferring your schematic into a PCB layout involves several critical steps to accommodate the 120V requirements.
Layout Guidelines:
- Trace Width: Calculate and adjust the trace width for 120V current loads to prevent overheating and ensure adequate current flow.
- Isolation: Maintain proper clearance and isolation between high-voltage and low-voltage parts of the circuit to prevent arcing and short circuits.
- Grounding: Implement robust grounding practices to enhance safety and circuit stability.
Step 5: Run Design Rule Checks (DRC)
Utilize EasyEDA’s DRC feature to automatically check your layout for errors that could lead to circuit failure or safety hazards.
Key DRC Settings for 120V:
Connectivity: Verify that all connections are secure and correctly routed, with no unintentional shorts.
Clearance: Check that clearances meet or exceed the minimum requirements for high-voltage applications.
Step 6: Prototype Your Board
Before finalizing your design, prototype your PCB to test and validate the functionality of the 120V elements.
Prototyping Tips:
- Use a Reliable Fabricator: Choose a PCB manufacturer experienced with high-voltage designs.
- Test Under Controlled Conditions: Perform initial testing using a variable transformer to gradually increase voltage to the design level to monitor behavior.
Safety Tips: Handling 120V Power
Working with 120V requires caution. Here are essential safety tips:
- Use Insulated Tools: Always handle high-voltage components with insulated tools to prevent accidental shocks.
- Wear Protective Equipment: Safety glasses and gloves are a must.
- Double-Check Connections: Ensure all connections are secure to avoid short circuits or loose connections that could lead to sparks.

Troubleshooting Common Issues with Your 120V Power Setup in EasyEDA
Learn how to identify and resolve common issues such as overheating, electrical noise, and intermittent connections in your 120V PCB designs.
1. Overheating Components: Components handling 120V may overheat due to insufficient trace width or inadequate thermal management. Check and adjust trace widths, and improve heat dissipation methods.
2. Voltage Drops: If you notice voltage drops across the circuit, it might be due to insufficient trace width or excessive load. Ensure that all traces are properly sized to handle the current without significant voltage drop.
3. Arcing or Short Circuits: High voltage can lead to arcing or shorts if clearances and creepage distances are not properly maintained. Review the PCB layout for adequate spacing between high voltage traces and other components.
4. Erratic Behavior or Noise: High voltage circuits can be susceptible to interference. Implement proper grounding and shielding techniques to minimize noise and ensure stable operation.
5. Component Failure: Components failing prematurely may be unsuitable for high voltages or could be defective. Verify component ratings and consider replacing them with higher-rated or more reliable alternatives.
6. Circuit Breaker Tripping: If the circuit breaker trips when your device is powered, there could be an issue with circuit design or a short circuit. Double-check the circuit design for any potential short circuit paths and ensure all components are correctly installed and not damaged.
