FFC PCB Design for 5050 LED
0:00
Autopilot
Work completed:
- Project description updated to “Flexible 10×20 mm FFC RGB+WW LED Module.”
- System Architecture mermaid diagram defined and saved.
- HL-5050RGBW-S1 footprint placed as LED1.
- 10 generic resistors (R1–R10) added and tied: each LED channel → resistor → corresponding edge pad net.
- PCB board size set to 10 mm × 20 mm, stackup set to Standard 4 Layer.
- Edge-pad components labeled for all 10 pads (R+, R–, G+, G–, B+, B–, W1+, W1–, W2+, W2–).
- Placeholders for resistor MPNs updated to RC0603FR-07500RL.
Tasks not done:
- Adding and positioning actual edge-pad footprints in PCB layout.
- Defining trace width classes and running Auto-Layout routing.
- Centering the LED footprint and arranging components for routing.
- Final ERC/DRC review on routed board.
Success criteria:
- ✅ Board size is 10 mm × 20 mm
- ✅ LED footprint placed
- ✅ 10 pad nets defined and labeled
- ✅ Resistor nets connected
- ❌ Edge-pad footprints are not yet placed
- ❌ ERC/DRC has not been run on the routed layout
Next step:
Place and position the 10 edge-pad footprints along the 10 mm board edge, then define trace classes and route the nets. Once routing is complete, we can run ERC/DRC to validate manufacturability.
