High Precision Magnesium Alloy Heat Sink AZ31B For Power Electronic & Semiconductor
Product Description
Magnesium alloy has excellent thin-wall casting performance and good specific strength, rigidity and impact resistance, which can fully meet the requirements of 3C products for high integration, lightness, miniaturization, impact resistance, electromagnetic shielding, heat dissipation and environmental protection. Therefore, the current 3C products such as mobile phones, notebook computers, digital cameras, camcorders, PDAs and other industries have also set off an upsurge in the development and application of magnesium alloy casings and parts. A number of companies specializing in the production of magnesium alloy parts for 3C products have been established in China.

Heat sinks are thermally conductive components or devices that absorb and dissipate heat generated by electronic components. Heat sinks cool high-powered devices to prevent overheating. The reliability of electronic components is generally reduced by the square of an increase in temperature. For example, doubling the ambient temperature around a component renders the component 25% less reliable than at the lower temperature. Heat sinks are therefore essential in dissipating generated heat and improving component longevity.
