Purpose：Metallographic cross-sectioning is performed to examine voids, intermetallic compound (IMC) layers, and other potential defects in PCB solder joints. The specimen is prepared by sectioning using the Table Cut 200 automatic flatbed cutting machine, cold mounting with TJ2226 cold mounting resin, and grinding and polishing using the Alpha 610 automatic grinding and polishing machine. The detailed sample preparation procedure is described in the following preparation method.

As a star coating in the field of catalysis, cuprous oxide (Cu₂O) coating is a typical p-type semiconductor with a band gap of approximately 2.2 eV. It can absorb visible light to initiate catalytic reactions, and is widely used in organic pollutant degradation, water splitting for hydrogen production, and other applications. Its catalytic activity directly depends on the microstructure and quality of the coating. Coatings prepared by electrochemical deposition, chemical reduction, and other methods can adhere tightly to the substrate and provide sufficient active sites for catalytic reactions.

Based on the metal-semiconductor junction forming a Schottky barrier, Schottky diodes conduct electricity through majority carriers without minority carrier storage effect. Their core advantages include ultra-low forward voltage drop (0.2–0.45V), extremely fast switching speed (ns level), and low power loss.
