Micro Components (MCL) develops, licenses, and produces aluminum-based advanced multilayer substrates for the high-power electronics industry. The company seeks to improve the functionality and reduce the weight of a wide range of products, including high-power LED lighting, power boards for automotive components, and power RF boards.
MCL has developed ALOX, a patent-protected multilayer substrate technology that aims to deliver better thermal management of high-power electronic modules and microelectronics packaging applications. The multilayered structure consists of a thermally conducting aluminum encompassed by electrically insulating anodized aluminum. The aluminum provides a direct metallic thermal path throughout the substrate, which is electrically isolated by the surrounding insulating anodized aluminum.
This aluminum and aluminum oxide structure is cladded by high-resolution patterned copper layers on both sides, enabling the signal routing. Thermally blocking materials with suboptimal thermal conductivity and reliability are not used, making ALOX substrates well suited to the fabrication of substrates and high-power semiconductor devices and modules.
