Round LED Light PCB Circuit Board PCBA OEM ODM Manufacturer
An aluminum PCB has a similar layout to any other PCB. It has a layer or layers of copper, solder mask and silkscreen layered over it. Instead of having a fiberglass or plastic substrate, though, an aluminum circuit board has a metal substrate. This base mainly contains a combination of aluminum. The metal core can consist entirely of metal or have a combination of fiberglass and aluminum. Aluminum PCBs typically are single sided, but can be double sided as well. Mulilayer Aluminum PCBs are highly difficult to manufacture.
Aluminum boards get the most use in LED and power converting electronics. The intense light produced by LEDs creates high levels of heat, which aluminum directs away from components. An aluminum PCB extends the lifespan of an LED device and provides more stability. You can find aluminum substrates in street lights, stop lights and household lighting. They allow power converters to change currents and regulate electronics. Creators in many other industries also find use in aluminum circuit boards, but they don't implement them as often.

Structure of Aluminum PCB Print Circuit Board:
1. Circuit Copper Layer
The circuit copper layer (usually using electrolytic copper foil)
is etched to form a printed circuit, which is used to realize the
assembly and connection of the device. Compared with the
traditional FR-4, with the same thickness and the same line width,
the aluminum substrate can carry a higher current.
2. Insulating Layer
The insulating layer is the core technology of the aluminum
substrate, which mainly plays the functions of bonding, insulation
and heat conduction. The aluminum substrate insulating layer is the
largest thermal barrier in the power module structure. The better
the thermal conductivity of the insulating layer, the more
favorable it is to spread the heat generated during the operation
of the device, and the lower the operating temperature of the
device, so as to increase the power load of the module, reduce the
volume, extend the life-span, and increase the power output .
3. Metal substrate
What kind of metal is used for the insulating metal substrate
depends on the comprehensive consideration of the thermal expansion
coefficient, thermal conductivity, strength, hardness, weight,
surface state and cost of the metal substrate.
In general, considering the conditions such as cost and technical
performance, aluminum plate is an ideal choice. Available aluminum
plates are 6061, 5052, 1060 and so on. If there are higher
requirements for thermal conductivity, mechanical properties,
electrical properties and other special properties, copper plates,
stainless steel plates, iron plates and silicon steel plates can
also be used.
