Aluminum pcb board is a kind of metal clad pcb with good heat dissipation, generally single sided aluminum pcb consists of three layers structure, named circuit layer(copper foil),insulated layer and metal base. For high-end use, aluminum pcb usually designed to be double sided, the structure is circuit layer, insulated layer, aluminum base, insulated layer and circuit layer.But multilayer aluminum pcb is very few in actural application, which can be laminated by ordinary multilayer pcb with insulated layer and aluminum base.
Power components are surface-mounted in circuit layer, the heat generated by device at running time is rapidly transmitted to metal base through insulated layer,then metal base transfer these heat out to achieve cooling the device. Compared with traditional FR-4, aluminum pcb can minimize thermal resistance, make the aluminum base having excellent heat transfer performance. Compared with thick film ceramic circuit board, its mechanical properties are excellent.
In addition, Aluminum pcb board also has the following unique advantages:
Comply with RoHs requirements.
More suitable for SMT process.
In the circuit design scheme, the thermal conductivity is extremely effectively, so as to reduce module operating temperature, prolong the service life, and improve the power density and reliability.
Reduce the assembly of radiators and other hardwares (including hot interface materials), reduce products volume, reduce hardware and assembly costs. Optimal combine power circuit and control circuit.
Replacing fragile ceramic pcb,gain better mechanical durability.
Aibixing Industrial is committed to solve the heat dissipation problem of high power LED lighting products, mainly produce high precision metal clad pcb,such as aluminum pcb board, copper core pcb, copper-al pcb and other high-end pcb related products.
