Circular Motor Control PCB Design
Budget: ₹12,500 – ₹37,500 INR
The job is to design a 4-layer circular PCB that can deliver a steady 40 A at up to 60 V for a motor-control application. The layout will host a mix of through-hole power devices and fine-pitch SMD logic parts, so pad sizing, clearances, and assembly access all matter.
Key technical points
• Current handling: wide copper pours, appropriate copper weight, via stitching, and thermal reliefs that still meet the 40 A spec.
• Safety at 60 V: adequate creepage and clearance, sensible layer stack-up, and controlled-impedance where needed for gate-drive or feedback lines.
• Form factor: the board is circular, so component placement, mounting holes, and edge-connector positioning must respect that geometry while keeping trace lengths short for low EMI.
• Mixed assembly: footprints must match both through-hole power stages (e.g., TO-220/247, large capacitors) and SMD control circuitry.
Deliverables
– Complete schematic capture (Altium, KiCad, or comparable professional tool)
– Layer stack-up and impedance notes
– PCB layout files and manufacturing Gerbers/ODB++
– Bill of materials with reference part numbers
– Assembly drawing and fabrication notes
The design will be considered finished when the above files pass standard DRC/ERC checks and a quick pre-production review with my manufacturer.
When you respond, focus on your experience with high-current motor controller boards, circular or irregular geometries, and mixed-technology layouts. Links or screenshots of similar work are welcome; a detailed proposal isn’t necessary at this stage.
