Metal core aluminum PCB
$66.99
Metal core aluminum PCB is typically structured with 3 layers: copper circuit layer, high thermal conductivity insulating layer, and aluminum base layer. The aluminum base allows the board conducts heat quickly, making it a perfect solution for the heat dissipation problem of high-power electronic devices. It is widely used in high-power LED lighting like car lights, motor drives, and more.

Questions & Answers
1. What is your lead time?
1-2 days. We have our own warehouse and stock in large quantities.
What solder mask color do you provide?
We provide Green, Red, Yellow, Blue, White, Black, and Purple.
3. What are your payment terms?
T/T, Paypal, Western union, L/C ,ESROW
4. What are the differences between aluminum core PCB and RF4 PCB?
The aluminum core PCB excels in heat dissipation due to its higher thermal conductivity than the RF-4 PCB. While the RF-4 PCB is cheaper than the metal core aluminum PCB.
5. Do your aluminum PCBs deal with high voltages?
Yes, our aluminum PCBs can be customized with reinforced dielectric layers to handle high voltages.
6. How many layers can an aluminum circuit board laminate?
In terms of layering, up to 4 or 6 layers is the general upper limit of the metal core aluminum PCB, including the aluminum substrate, copper conductive layer, and 2 dielectric layers.
7. What is the general thickness of the aluminum layer?
The aluminum thickness generally ranges from 2mm to 8mm.
8. What is the thermal conductivity of metal core aluminum PCB?
Standard aluminum PCBs have 1-3 W/m ·K, and high-performance versions can reach 5-8W/m·K.
9. How many types of aluminum base PCBs do you support?
We support customizing all types of aluminum base PCBs: single-layer aluminum PCBs, double-layer aluminum PCBs with single-component mounting side. 4-layer aluminum PCB. Contact our expert with your specific requirements to get your best solutions.
10. What is the thermal conductivity of Al cores? Can you provide UL certs?
The thermal conductivity of aluminum core is 2.0–5.0 W/mK, and that of copper core is 350–400 W/mK. We provide those certifications： UL, ISO9001, ISO13485, and IPC610 compliant.
