BECE SINSTA-STRIP AT 25 – Efficient single-stage stripper for clean copper surfaces

BECE SINSTA-STRIP AT 25 is a nitric acid-based one-step stripper specifically designed for the removal of electroplated tin and tin/lead layers from copper surfaces. This powerful product offers a fast and reliable solution for the demanding requirements of PCB processing.

Outstanding Features

  • Fast Stripping Speed: Removes tin and tin/lead at a rate of 5–8 µm/minute, even with high metal loads.
  • High Capacity: Handles metal loads with densities up to 1.40 g/cm³ without losing effectiveness.
  • Anti-Sludge Technology: Special additives reliably prevent sludging, even at high metal concentrations.
  • Copper Protection: Inhibitors protect copper surfaces from attack without affecting the stripping speed.
  • Perfect Surface Quality: Additives and integrated tarnish protection prevent oxidation, leaving uniformly shiny copper surfaces.
  • Effluent-Friendly Process: Free from peroxides, fluorides, and ammonium, significantly simplifying wastewater treatment.
  • Optimized for Horizontal Systems: Ideal for horizontal conveyor systems with 2.5–3.5 bar spray pressure.
  • Versatile Application: Can also be used as an immersion stripper to meet diverse process requirements.

BECE SINSTA-STRIP AT 25 is a reliable and fast tin stripper designed to remove tin and tin/lead layers efficiently. Combining outstanding performance with excellent surface quality, it ensures easy handling and seamless process integration.
