LED lighting PCB is actual Aluminum core PCB, it’s a unique metal based copper clad laminate aluminum substrate. It has good thermal conductivity, electrical insulation performance and mechanical processing performance.
Aluminum base copper clad laminate is a metal circuit board materials, copper foil, thermal insulation layer and the metal substrate composition, its structure is divided into three layers:
The circuit layer (i.e. copper foil) usually is printed circuit board after etching, which are connected with each other in various parts of the assembly, under normal circumstances, with the current carrying capacity of the circuit layer greatly, which should use thick copper foil thickness from 35 μm~280 μm; thermal insulation layer is the core technology of MCPCB, it generally, a special polymer filled by special ceramic thermal resistance small, viscoelastic properties, thermal aging ability, able to withstand mechanical and thermal stress.The metal base is a supporting member of aluminum substrate, with high thermal conductivity, usually aluminum, can also use copper (copper which can provide better thermal conductivity), suitable for drilling, punching, cutting and other conventional mechanical processing.
King Sun used aluminum based materials, compared with other materials incomparable advantages. Suitable for power assembly surface mount SMT public art. Without radiator, the volume is reduced, the cooling effect of excellent insulation properties and good mechanical properties.
Use in power hybrid IC (HIC).
King Sun PCB have engaged in developing and manufacturing metal core base PCBs(MCPCB) since 2005,now commonly used in LED lighting to increase longevity,our MCPCBs be recognized with great reliability and play a major role in excellent heat dissipation.
