Alüminyum PCB
YC PCB supplies custom aluminum PCB, aluminum circuit board and aluminum substrate board for LED lighting, power electronics and heat-sensitive assemblies. Orders can include bare boards or complete PCBA with component sourcing, SMT/THT assembly and testing.
What Is Aluminum PCB?
An aluminum PCB combines a copper circuit layer, thermally conductive dielectric and aluminum base to transfer heat away from LEDs or power components. It is a practical choice when your product needs better heat dissipation than FR4 while controlling board weight and cost.
Your production specification should define copper thickness, dielectric thermal conductivity, insulation strength, aluminum base thickness and surface finish.
Aluminum PCB Details to Confirm
Available aluminum PCB configurations include round, linear and custom outlines with different LED pad layouts, thermal materials and surface finishes. Select the configuration that matches your fixture, heat sink and assembly process.
Round boards are available for UFO high bay lights, ceiling fixtures and circular LED modules, with mounting holes and LED spacing produced to your drawing.
Linear boards are supplied for tube lights, light bars, cabinet lights and other long LED modules, with custom length, width and panelization.
LED pad size, current path, copper area and solder mask openings are manufactured to the approved Gerber and assembly files.
OSP, lead-free HASL, ENIG and silver plating are available according to solderability, storage and assembly requirements.

Match Thermal Needs to the Right Board
Select the board material by considering heat load, current, LED density, dielectric thickness and assembly method. The most suitable route balances thermal performance, manufacturing cost and production stability.
Provide LED power, expected heat load, board size, copper distribution and heat sink interface so the quotation can match a standard aluminum, high-thermal aluminum or copper substrate route.
- Common LED modules and lighting boards
- Balanced cost and heat transfer
- Useful for prototype and volume orders
- High-power LEDs or dense layouts
- Better dielectric thermal path
- Specify the required thermal conductivity in the RFQ
- Demanding LED and power modules
- Higher thermal target or thermal separation needs
- Compare thermal performance, cost, weight and machining requirements
Aluminum PCB Thermal Structure
The copper circuit, dielectric layer and aluminum base work together to control heat transfer and electrical insulation. Production follows the approved stack-up and mechanical drawing.
Heat travels from the LED pad through the copper layer and dielectric into the aluminum base and product heat sink.
Specify thermal conductivity, dielectric thickness and insulation strength according to the operating voltage and temperature target.
Pad shape, trace width, current path, solder mask opening and LED polarity are controlled according to the approved design.

Aluminum PCB FAQ
Answers to common purchasing questions about aluminum PCB materials, thermal performance, finishes, assembly, order quantities and quotation files.
What is an aluminum PCB?
An aluminum PCB is a metal core circuit board that uses an aluminum base to transfer heat away from LEDs or power components through a thermal dielectric layer.
Is aluminum PCB better than FR4 PCB?
Aluminum PCB is usually better for heat dissipation, while FR4 is often better for general routing density and lower thermal load. The right route depends on power, heat, cost and assembly needs.
Can YC PCB manufacture LED aluminum PCB?
Yes. YC PCB manufactures LED aluminum PCBs with reflective solder mask, selected surface finish and custom LED layouts, and can also supply assembled boards with connectors and agreed testing.
What files are needed for an aluminum PCB quote?
Please send Gerber RS-274X, Excellon drill file, board outline, material requirement, copper weight, thermal conductivity target, quantity and BOM if assembly is needed.
Which surface finish should I choose?
HASL-LF, OSP, ENIG and silver plating are available. Select the finish according to solderability, storage time, assembly process and application.
Can aluminum substrate board be assembled with LEDs?
Yes. For LED PCBA, provide the BOM, pick-and-place file, LED polarity, test requirements, lens or connector clearance and packing instructions.
When should I choose high thermal aluminum PCB?
Choose high thermal aluminum PCB when standard aluminum PCB may not remove enough heat for high-power LEDs, dense LED layouts or power modules.
Can I order prototypes or small batches?
YC PCB supports prototypes, small batches and volume production. Lead time is confirmed after the files, materials, quantity and assembly scope are defined.
