4-Layer Consumer Electronics(Energy Meter) PCB Design
Budget: ₹1,500 – ₹12,500 INR
I’m developing a smart energy meter for consumer deployment and now need an experienced PCB designer to take the design from schematic refinement through to production-ready 4-layer PCB files. The board must be compact, electrically robust, and capable of safely handling 240V AC with current ranges up to 60A, while maintaining proper isolation and signal integrity.
The design will involve a mixed-signal environment, where accurate metering, stable power delivery, and noise-sensitive digital communication must coexist without interference. The multi-layer stack will be critical to ensure clean grounding, separation of high-voltage and low-voltage domains, and EMI control.
Core requirements :
• Integration of an energy metering IC and microcontroller (exact components will be shared at project start).
• High-voltage input stage supporting 240V AC, 10–60A range, with proper protection and isolation.
• Stable and efficient low-voltage power supply (3.3V / 5V rails) derived from mains.
• Clear separation between high-voltage and low-voltage sections, including isolation boundaries.
• Provision for communication interfaces (UART/SPI/I2C or wireless module headers if needed).
Deliverables:
1. Clean and well-structured schematic (Altium, KiCad, or Eagle — with full source files).
2. Defined a 4-layer stack-up and optimized PCB layout considering EMI/EMC and safety standards.
3. Complete fabrication package: Gerber files, NC drill, fabrication drawings, and Pick-and-Place data.
4. Brief design note explaining grounding strategy, isolation approach, and power routing decisions.
Acceptance criteria :
• Design passes DRC as per manufacturer constraints (to be shared).
• Proper creepage and clearance maintained for high-voltage sections.
• Solid ground plane strategy with minimal noise coupling into sensitive analog/digital circuits.
• High-current traces sized appropriately with thermal considerations.
• All signals are correctly labeled and consistent with the schematic.
For NCR location only
