Silver soldering process
Various contact before soldering chemical or mechanical method is used to remove oxide film on the surface of the weldment, carefully clean the surface of the weldment using gasoline or alcohol, to remove surface oil, grease, dirt, and prevent wetting and flow of dirt.For small welding pieces, the adhesive reservation is selected to ensure that no displacement is carried out in the loading and loading of solder, and the adhesives used are not harmful to brazing. For large welding parts or special contacts, the assembly positioning must be carried out through a fixture with a bump or groove, and the welding parts are in a stable state
High quality raw materials
The company adopts high-purity cathode copper (copper content reaches 99.99%), general No.1 electrolytic copper content is 99.95%, silver adopts high-purity No.1 (1 × 1) silver, and phosphor copper alloy adopts high-quality alloy, which reduces the proportion of impurities in raw materials.
