Description

Technical Field

[0001] The invention belongs to the technical field of electronic processing, and in particular relates to a chip resistor electroplating processing device. Background Art

[0002] SMD resistors, also known as chip fixed resistors, are a type of metal glass glaze resistors. They are made by mixing metal powder and glass glaze powder and printing them on a substrate using screen printing. They are resistant to moisture and high temperatures, have a small temperature coefficient, can greatly save circuit space costs, and have more sophisticated designs. They are widely used in circuit boards for mainstream electronic products.

[0003] Chip resistors usually consist of several parts: ceramic substrate, back electrode, surface electrode, resistor body, primary glass, secondary glass, end electrode, middle electrode, and external electrode. The production process is roughly as follows: placing ceramic substrate → back conductor printing and drying → positive conductor printing and drying → sintering → resistor layer printing and drying → sintering → primary protective layer printing and drying → sintering → laser trimming → secondary protective layer printing and drying → sintering → resistance code printing and drying → sintering → strip folding → vacuum sputtering → drying → grain folding → Ni, Sn electroplating → drying → magnetic screening → resistance test screening → taping, etc.

[0004] Existing electroplating treatment usually uses a drum to perform electrolytic plating in a plating solution. The drum end serves as the cathode of the electrolysis and gains electrons that are reduced to nickel / tin at the cathode end. The electrolytic cell end uses Ni metal / Sn metal as the anode to lose electrons and oxidize to Ni2+ / Sn2+, thereby replenishing the nickel / tin ions in the electrolyte. During the electrolysis process, in order to obtain better conductivity, Al2O3 balls and Steel balls are generally added to the drum before electroplating for more uniform stirring.

[0005] However, after the electrolysis is completed, the resistor needs to be separated from the ball. Currently, most of the operations are done manually, which cannot meet the factory's demand for efficient production. This problem needs to be solved urgently. Summary of the invention
