The main characteristics that reflect the quality of direct plating are the conductivity of hole wall and the deposition rate of copper plating layer. The condu...
Zinc dissolves easily in acids and also in alkalis, so it is called an amphoteric metal. Zinc changes little in dry air. In moist air, the zinc surface will for...
