Basic Material: Aluminum
Aluminum base (Al base) is a high-tech compound designed to produce printed circuit boards and components with high heat release rates. In addition, the material Al base has high strength characteristics and withstands significant mechanical and vibration loads.
Aluminum is produced in the form of sheets separated by copper. Essentially the basic material is a one-sided printed circuit board which is pasted to an aluminum plate.

The boards are made on oxidized aluminum sheets with a copper foil pasted over it. The feature: there is no possibility to make transition vias — such PCB are single-layer.
The boards are processed by chemical methods. As a basis an elastic aluminum alloy (5052) alloyed with chromium and magnesium is used in the percentage content 0.15−0.35% and 2.2−2.8%, respectively. Foil fiberglass, pre-impregnated with epoxy resin, is used as a bond ply (dielectric layer).
The heat conduction of the entire printed circuit board is from 0.8−10 W/m∙K.

The heat generated from the components passes quickly through the dielectric plate and it is easily dissipated over the reliably pasted radiator - an aluminum base.
