OEM 15W 80mm Circular Aluminum LED PCB Board Supplier China

Designed for high-heat LED lighting structures, an Aluminum PCB (MCPCB) helps move heat away from the light source area and into the housing faster than standard FR-4. For round lamp formats like downlights, ceiling lights, and panel modules, the circular 80mm outline improves mechanical fit and keeps thermal paths short—helping the whole product run cooler and last longer.

key manufacturing focus (pcb only, no assembly):

• thermal stack control: stable dielectric thickness and thermal conductivity options to match your heat targets

• copper and trace capability: copper thickness options and controlled etching for repeatable current paths

• surface finish choices: common finishes such as ENIG/OSP/HASL (as required by your design)

• solder mask and legend: clean white/black mask options for lighting aesthetics and readability

• reliability checks: electrical test, dimensional inspection, and process control for consistent batches

customization for oem / b2b orders:

• board diameter and cutouts: adjust round size, holes, slots, and tooling features for your housing

• layer count and copper weight: optimize for thermal and current requirements

• panelization: efficient panels for automated downstream processing and better yield

If you share your Gerber and stack-up targets (copper weight, dielectric, surface finish), we can recommend a cost-effective Aluminum PCB structure for your 15W-class circular design.
