In recent years, silver coated copper powder has been widely used, not only as the electrode of chip electronic components, but also in the fields of catalyst and electronic paste. At present, the electronic paste used in my country is basically micron-level pure silver powder, which is expensive and mainly imported. Micron sterling silver powder has the problem of particle sedimentation in the large-scale mechanized production process of electronic products. The silver-coated copper powder can effectively solve this problem, and can reduce the amount of silver and product cost, and has a broad market prospect.

Silver coated copper powder has many uses, but its preparation process needs to be further improved. The displacement plating process is simple and the cost is low, but the plating layer is relatively loose, and the deposition rate is not easy to control; the thickness of the electroless plating layer is uniform and the pinhole rate is low, but the process is relatively complex, and the stability of the plating solution is poor, and the reaction speed is too fast . By adopting the composite technology of displacement and chemical deposition, the advantages of displacement plating and chemical reduction plating can be combined, the process is simple, the cost is low, the deposition speed is fast, and it is easy to control. In the foreseeable future, substitution and compounding will become the mainstream process for preparing silver-coated copper powder.
