Production of high thermal conductivity substrates for ultrabright LEDs and other electronic devices using proprietary ALOX technology

The project is based on patented technology ALOX™ from Israeli company MCL. Substrates manufactured with the technology are made of a conducting layer of aluminum or copper and a dielectric material with nanopourous structure. The dielectric material creates considerable competitive advantage: pores measuring 65 nanometers to 90 nanometers that have been suffused with special nanofillers achieve thermal conductivity of up to 200 W/m*K, dielectric breakdown voltage of more than five kilovolts, and good thermomechanical properties.

High thermal conductivity LED substratesSubstrates produced with ALOX™ technology have passed all necessary testing, including tests for thermal reliability. RUSALOX’s products outstrip alternatives on basic consumer characteristics — heat conductivity, by hundreds of times; price, by 20 percent to 30 percent; and reliability, by two orders of magnitude. Leading international players in the LED market are currently considering using the company’s products.

Commissioned in February 2012, RUSALOX’s factory is the first in Russia to produce high thermal conductivity substrates and panels for electronic devices, primarily for LEDs requiring superior heat sinks. In its first phase of operations, the Vladimir factory will produce 10,000 panels per month, providing enough output to assemble more than one million LED lamps.

Light-emitting diodes are semiconducting devices that transform an electric current into a light ray.

LED lamps have substantial advantages in comparison with traditional light sources. But they also have a basic problem: The crystal that radiates light heats significantly when lit. With rising temperature, the crystal gives off less light, and the service life of the LED lamp is shortened.

Israeli company Micro Components Ltd. was able to resolve this problem with its ALOX technology, which lowers the temperature of the crystal with rapid heat sink. At the heart of the technology is a process of selectively staged aluminum oxidation in which dielectric material is obtained on the surface of the metal and in its depths. MCL was the first company in the world to form a structure of insulating conductors inside the metal while obtaining an oxide. MCL’s approach resulted in a new type of inexpensive backplane with high heat conductivity.

Drilling and plating of perforations are not required with ALOX™ because the interconnections are made entirely of aluminum and the dielectric material is made of high-quality ceramic material. The process is simple, low cost, and requires a limited number of operations.

ALOX™ is a broad technological platform that can be applied in packaging various electronic goods: microwave electronics, SiP (system-in-package) technology, three-dimensional memory stacks, MEMS devices, and powerful modules and components.
