Production method of burr-defect-resistant tin plating plate

The invention discloses a production method of a burr-defect-resistant tin plating plate, and relates to the field of tin plating product processing. The method comprises the steps of according to theburr-defect-resistant requirement of the tin plating plate, determining a side mixed crystal area requirement, a thickness uniformity requirement, a passivating film thickness uniformity requirementand a paint film uniformity requirement of the tin plating plate; according to the side mixed crystal area requirement and the thickness uniformity requirement of the tin plating plate, determining atrimming amount range of a cold rolling process of the tin plating plate; according to the passivating film thickness uniformity requirement of the tin plating plate, determining a passivation currentdensity range of the tin plating plate in a tin plating process; and according to the paint film uniformity requirement of the tin plating plate, determining a slotted shape of a coating roller.
