Abstract
This invention relates to a method of manufacturing an aluminum substrate for printed circuits. It comprises an oxide layer forming step, and a heat-drying step. For the oxide-layer forming step, an anodic oxide layer is formed on at least one surface of an aluminum plate by anodizing the aluminum plate in an electrolytic solution. The phosphoric acid has the concentration: 3 to 20 mass%, and bath temperature is more than 25 DEG C, but less than 40 DEG C. For the heat-drying step, the anodic oxide layer is dried by heating it at 150 to 300 DEG C for 0.5 to 3 hour. By means of this way, it forms a good oxide layer. Eventually, it enhances adhesiveness with a resin plate for manufacturing printed circuits of an aluminum substrate.
