Definitions

  • the invention relates to a method for tinning Pipes, pipe sections, fittings and fittings made of copper or a copper alloy by chemical deposition a tin layer from a tin bath using conventional Procedural measures such as rinsing, pickling and drying.
  • Pipes, pipe sections, fittings and fittings and the like Facilities used in cold and hot water service systems are used to a large extent made of copper and copper alloys. The reasons for this are the good corrosion resistance of copper and copper alloys as well as the easy processability of these metallic materials for pipes and the like.
  • the tin used for this contains the tin a complexing agent such as thiourea, the the copper complexes so strongly that its potential in System is lower than that of tin. That with it noble tin is deposited on the copper; Copper dissolves in return on. The separation takes place mainly as long as free copper is still available.
  • the invention has for its object the above described Defects and deficiencies in the state of the art to overcome and an improved tinning process of pipes and the like made of copper or a copper alloy to provide.
  • This object is achieved in a method of Type described above solved in that one Tin bath used, the methanesulfonic acid and / or a Contains methanesulfonic acid salt. That with the invention The tin bath used is - aside from that Addition of methanesulfonic acid or a salt - a common one Tin bath used for chemical or electroless plating of tin layers is used, but so far exclusively in printed circuit board production.
  • the pH of the tin bath is 0 to 3, preferably 0 to 1st
  • Carrying out the chemical deposition of the tin layer takes place in the usual way, for example at temperatures from 50 to 80 ° C.
  • the pre- and post-treatment of the tinned workpieces takes place in a manner known per se. So can be usual Rinse, pickling and drying stages can be provided. According to one preferred embodiment of the invention, however, is Drying stage carried out under a nitrogen atmosphere.
  • the copper parts to be tinned are dipped in or flowed through in the bath composition below.
  • Methanesulfonic acid 100 g / l Tin methanesulfonate 40 g / l Thiourea 150 g / l Sodium hypophosphite 50 g / l Wetting agent 5 g / l temperature 80 ° C
  • Fluoroboric acid 100 g / l Tin fluoroborate 30 g / l Thiourea 100 g / l Sodium hypophosphite 50 g / l Wetting agent 5 g / l temperature 70 ° C
