Solderon™ BHT-350 Bright Tin for Connectors

 
 
 

Solderon™ BHT-350 Bright Tin is a high speed, sulphonate–based tin electroplating product formulated for continuous electroplating of wire and connector strip in reel-to-reel machines. The Solderon BHT-350 Bright Tin electrolyte is free of volatile aldehydes and may be operated at temperatures up to 50°C.

The Solderon BHT-350 Bright Tin electrolyte provides bright deposits over a wide current density range. Its propriety formulation controls both grain size and carbon content in deposits which results in a very ductile bright deposit. Solderon BHT-350 Bright Tin products do not contain methanol ensuring a more environmentally friendly electrolyte compared to other conventional bright tin processes. Analytical procedures are available for all bath components.

  • Fully bright deposit over the whole current density range
  • Low Carbon–content in the deposit (< 0.2 % up to 40 ASD)
  • High deposit ductility ( > 11%)
  • Very low whisker growth tendency
  • Low degree of reflow discoloration
  • Operating temperature up to 50°C: no cooling system required
  • High plating current density: 5 – 40 ASD
  • Easy bath control and fully analyzable components
  • Low foaming electrolyte: suitable for high speed applications
  • No black foam line: suitable for selective plating and full strip plating
  • Also suited to low speed rack and barrel applications
