Frequently Asked Questions
Aluminum PCB FAQ
01Which thermal conductivity should I choose?
For standard indoor LED use 1.0 – 1.5 W/m·K. For automotive / high-power LED use 2.0 – 3.0 W/m·K. ADAS / LiDAR and military-grade heat paths need 4.0 W/m·K.
02Can aluminum PCBs have plated through-holes?
Standard single-sided MCPCB uses non-plated holes. For plated through-hole on metal core we switch to copper-core builds — these support PTH but cost ~30% more.
03What is the thermal advantage vs FR-4?
Standard FR-4 is 0.3 W/m·K. A 2 W/m·K MCPCB moves heat ~6× faster to the metal base, dramatically extending LED life and keeping junction temps stable.
04What is the typical lead time?
Single-sided MCPCB: 4–6 business days. Double-sided: 7–10 days. Multi-layer metal core: 10–15 days.
