An aluminum-core LED PCB uses an aluminum metal base, dielectric layer and copper circuit structure to create a more direct thermal path away from heat-generating LEDs and power components. This construction is commonly selected for LED lighting, power electronics and other thermally demanding assemblies where conventional FR-4 may not provide the required heat-transfer path. JETFGO reviews the complete aluminum PCB construction together with aluminum-core material, dielectric structure, copper requirements, finished board thickness, mechanical outline and component heat locations before confirming manufacturability. Our published capability reference for this solution includes aluminum metal-core materials, rigid PCB thicknesses from 0.3–8.0 mm and profiling options including routing, punching, V-cut and beveling. Final material and construction selection depends on thermal, electrical and mechanical requirements. For LED applications, thermal performance depends not only on the aluminum base but also on the dielectric layer, copper structure, component thermal pads, board thickness and the thermal path into the final assembly. These factors should therefore be reviewed together during DFM. For engineering review, provide Gerber or ODB++, drill files, proposed stack-up, fabrication drawing, quantity, target delivery date and any thermal, dielectric, mechanical or LED assembly requirements. Published capability values are provided for initial selection. Final aluminum-core material, dielectric structure, thickness, profiling method and manufacturing feasibility are confirmed through project-specific engineering and DFM review.
Published limits are drawn from JETFGO’s current capability chart. Final feasibility depends on the complete data package and engineering review.Aluminum-Core LED PCB

Technical questions
Published limits are drawn from JETFGO’s current capability chart. Final feasibility depends on the complete data package and engineering review.
01What is an aluminum-core LED PCB?+
An aluminum-core LED PCB is a metal-base circuit board that uses an aluminum base, dielectric layer and copper circuitry to transfer heat away from LEDs and other heat-generating components more efficiently than a conventional PCB construction.
02Which files help JETFGO review an aluminum-core LED PCB fastest?+
Send Gerber or ODB++, drill files, proposed stack-up, fabrication drawing, quantity, target delivery date and any aluminum-core, thermal, dielectric, copper or mechanical requirements.
03Can JETFGO support prototypes and repeat production for aluminum LED PCBs?+
Yes. Once the aluminum-core material, dielectric structure, copper requirements, thickness and mechanical construction are confirmed, the approved engineering record can support prototype validation and repeat production.
04Why is aluminum used for LED PCBs?+
Aluminum provides a metal base that helps transfer heat away from LEDs through the dielectric and copper structure into the surrounding thermal assembly. This makes it useful for lighting and other heat-intensive electronics.
05What is the difference between an aluminum PCB and an FR-4 PCB?+
An aluminum PCB includes a metal base designed to support heat transfer, while a conventional FR-4 PCB uses a fiberglass-reinforced laminate structure. Material selection depends on thermal, electrical, mechanical and cost requirements.
06Does the aluminum core alone determine LED PCB thermal performance?+
No. Thermal performance also depends on the dielectric layer, copper structure, component thermal pads, board thickness, heat-source layout and the thermal connection between the PCB and final assembly.
07Which profiling methods are available for aluminum-core PCBs?+
JETFGO can review aluminum-core PCB projects requiring routing, punching, V-cut or beveling. Final profiling method depends on board thickness, outline, panel structure and mechanical requirements.
08Can aluminum-core PCBs be used for high-power LEDs?+
Yes, aluminum-core PCBs are commonly evaluated for high-power LED applications where heat transfer is a major design requirement. Final suitability depends on LED power, dielectric performance, copper design, board structure and the complete thermal path.
