2. Performance Characteristics
- Superior heat dissipation: the aluminum base directly conducts heat from LED chips to the heatsink, significantly reducing junction temperature compared to standard FR-4 PCB
- Lower thermal resistance: thermally conductive dielectric layer minimizes heat transfer resistance between copper circuit and aluminum base
- Extended LED lifespan: by keeping LED chips at lower operating temperatures, lumen depreciation is reduced and service life is extended
- High current carrying capacity: thick copper foil (up to 3oz) supports high-current LED driver circuits
- Stable electrical insulation: dielectric layer prevents short circuit between copper traces and aluminum base, with high breakdown voltage
- Good mechanical strength: rigid aluminum base resists warping during soldering and operation
- Low water absorption: stable performance under high humidity environments
- Dimensional stability: consistent flatness for reliable LED component mounting
