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.
