Aluminum PCB is one kind of Metal core PCB, which consists of three layers, copper layer, insulation layer and aluminum core material. It has its unique advantage, maintains a high heat emission efficiency, which is widely used in LED industry.
Classification of Aluminum PCB
1. 1000 series, there are 1050, 1060, 1070 material which is almost100% pure aluminum material. The price is most cost effective of all PCB materials. What used mostly of 1000 series material is 1050 and 1060 at Linked Electronics. The aluminum content is more than 99.5%.
2.5000 series, 5052, 5005, 5083 materials, which is now widely used in aviation, buildings and transport and automotive industries. 5000 series material is alloy of aluminum and 3~5% magnesium. It has very high strength and lower in weight.
3. 6000 series, 6061 is the most typical material. 6000 series are alloyed with magnesium and silicon. They are easy to machine, are weldable, and can be precipitation hardened, but not to the high strengths that 2000 and 7000 can reach. 6061 alloy is one of the most commonly used general-purpose aluminium alloys.
Storage
Aluminum PCB generally store in a dark and dry condition. Most Aluminum PCB will easily get damp, turn black or yellow. After the vacuum package is open, it should be assembly in 24 hours.
Surface Treatment of Aluminum PCB
Generally, all surface treatment could be applied to aluminum boards, HASL lead free aluminum PCB, OSP Aluminum PCB, immersion gold PCB, and immersion silver PCB. Considering the cost, OSP is surface treatment for aluminum printed circuit board that most customer choose at Linked Electronics.

White Aluminum Based PCB Custom Printed Circuits for LED 1.6mm 35um
Linked Electronics is a China based PCB manufacturer with full in house manufacturing capabilities, which specialized in high-mix, prototype, low volume and quick turn PCBs and PCBA services
Compared with other electronic products, LED products will generate much more heat , which required the PCB to have a better ability for heat dissipation . Due to its characteristics, metal core PCB, which are generally has better heat dissipation are frequently used on LED PCB. Aluminum core PCB is the most common used on LED PCB. This is because the aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.

The advantages of Aluminum PCB & Metal core PCB
● Thermal transfer more efficient than a conventional rigid FR4 standard PCB Board
● Heat dissipation is superior to standard FR4 substrate PCB board.
● Dielectrics can be adjusted to suit your thermal or insulation level requirements
● Power densities can be increased while components are kept cool,which can increase product life and durability
● Cooling properties allow devices to be driven harder or de-rated for lower cost components.
