Aluminum PCB thermal design of electronic components inside the device temperature control, allowing the device in the environment as well as the maximum temperature does not exceed the standard specification. The maximum temperature range should be based on analysis of earnings components, and linked to the reliability of the product.
Aluminum circuit board with a circuit layer, thermal insulation layer and the metal substrate composition, circuit layer requires a strong current carrying capacity and thus should use thick copper foil, thermal insulation layer is the core technology of aluminum circuit boards, usually filled with special ceramics polymer, thermal resistance, excellent viscoelastic properties, with the ability to heat aging, mechanical support and thermal stresses.
As we all know, high density, high power heat volatilization more difficult, will inevitably lead to failure due to high temperature electronic components, and clever touch aluminum circuit board problem. With the continuous development of China's electronics industry, the board will be used in electronics, communications, power, audio, and other industrial fields.
