Aluminum 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 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.
