Abstract

The invention relates to an electronic diode for iron alloy lead wire rectification and a preparation method thereof. The electronic diode includes a casing, internal components and lead wires, and is characterized in that the lead wire is an iron alloy lead wire, and the suitable weight composition of the iron alloy is carbon<0.05%, manganese<0.20%. , silicon < 0.01%, sulfur < 0.01%, phosphorus < 0.013% and the rest of iron, using iron alloy leads instead of pure copper leads, which significantly reduces production costs; the simple and easy preparation method is followed by lead wires, filling, welding, pickling , White glue, molding and electroplating, the welding uses a special flux, and all the tops of the ferroalloy leads are coated.

Description

technical field [0001] The invention relates to an electronic diode for ferroalloy lead wire rectification and a preparation method thereof, which is used for reducing the production cost of the electronic diode. Background technique [0002] Diodes for rectification are widely used and can be seen everywhere. Its production process is also mature and large-scale automation. Leading, filling, welding, pickling, white glue, molding and electroplating are carried out in sequence. Among them, electroplating mainly refers to tin electroplating, and pickling includes Mixed pickling, phosphoric acid-hydrogen peroxide washing and ammonia washing, generally there is final pure water oscillation treatment. In the existing rectifier diodes, due to various factors, the leads are all pure copper leads, which are very expensive, resulting in high production costs, but because there are no other metal leads available, it cannot be selected. In the corresponding pickling, the control cond...
