Aluminum PCB & MCPCB Sourcing for Thermal Management
2 resources tagged with "Thermal Management"
Thermal management in LED and power electronics often comes down to the metal-core PCB (MCPCB), where an aluminum base spreads heat the standard FR4 board can't. The key spec is the dielectric layer's thermal conductivity, typically 1–3 W/m·K, paired with a 5052 or 6061 aluminum base and an ENIG or HASL finish. For LED and power work, IPC-6012 Class 2 or Class 3 sets the quality bar, so confirm the dielectric W/m·K rating and class against your thermal budget rather than trusting a generic 'aluminum PCB' listing.
When you source MCPCBs for thermal management, the pitfall is an under-spec dielectric that doesn't move heat as claimed — we verify the W/m·K rating, aluminum alloy, and IPC-6012 class against the actual thermal load.

FAQ
What thermal conductivity do aluminum PCBs offer?
The dielectric layer typically runs 1–3 W/m·C depending on grade. Higher conductivity moves more heat from LEDs or power devices but costs more, so match it to your thermal load.
What quality standard applies to MCPCBs?
IPC-6012 Class 2 for general use and Class 3 for high-reliability applications. Confirm the class, aluminum alloy (5052/6061), and surface finish (ENIG/HASL) match your requirements.
