How to Design LED Downlight Aluminum PCB for Optimal Heat Dissipation?

Optimal heat dissipation for a LED Downlight Aluminum PCB starts with three key design steps: expand heat pads, add sufficient thermal vias, and use appropriate copper thickness.

Key Design Tips for Heat Dissipation

  • 1. Enlarge heat pads: Extend LED pad areas to increase heat transfer, avoiding minimal pad sizes that trap heat.
  • 2. Add thermal vias: Use 0.3mm vias spaced 1.5mm apart, with plugging and copper cladding to form a 3D heat dissipation channel.
