^{Composition of the Aluminum PCB substrate:}

^{Circuit layer}

^{The circuit layer (usually electrolytic copper foil) is etched to form a printed circuit, which is used for the assembly and connection of devices. Compared with the traditional FR-4, the aluminum substrate can carry a higher current with the same thickness and linewidth.}

^{Insulating layer}

^{The insulating layer is the core technology of aluminum substrate, which mainly plays the functions of bonding, insulation, and heat conduction. The insulating layer of the aluminum substrate is the largest heat conduction barrier in the power module structure. The better the heat conduction performance of the insulating layer is, the more conducive to the diffusion of the heat generated during the operation of the device, the more conducive to reduce the operating temperature of the device, so as to achieve the purpose of increasing the power load of the module, reducing the volume, extending the service life and improving the power output.}

^{Metal base}

^{What kind of metal is used for 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?}

^{Generally, considering the cost and technical performance, the aluminum plate is the ideal choice. If there are higher requirements for heat conduction performance, mechanical performance, electrical performance, and other special performance, copper plate, stainless steel plate, iron plate, and silicon steel plate can also be used.}
