ALUMINUM MICRO-CONTROL METHOD USING CHEMICAL POLISHING

摘要

Disclosed is a method for controlling fine forms on aluminum by using chemical polishing. According to the present invention, the method for controlling fine forms on aluminum by using chemical polishing includes: a substrate preparing step of inspecting the purity and surface of an input aluminum substrate; a chemical polishing execution step of executing a chemical polishing operation to make the surface of the aluminum substrate glassy, remove impurities from the surface, and make the surface flat based on the concentration and temperature corresponding to cracks formed on the aluminum substrate; a hot air drying step of drying the aluminum substrate done with the chemical polishing with hot air in an electric furnace in order to prevent stains on the aluminum substrate done with the chemical polishing; a process inspection step of determining whether the chemical polishing operation on the dried aluminum substrate is completed normally; and a packing and protection-taping step of packing and protection-taping the aluminum substrate when fine forms on the surface of the aluminum substrate are in a good state after the chemical polishing operation is determined to be completed normally in the process inspection step.
