1. Product Overview
ATRON® SP 200 is a water-based, alkaline surfactant cleaner engineered for the effective removal of baked-on fluxes from solder pallets and condensation traps. Additionally, it can be applied to unsoldered solder pastes on SMT stencils, conveyor fingers, and for manual removal of stubborn flux residues in solder ovens. Its long bath life—three to ten times that of traditional cleaners—significantly reduces bath changes, waste disposal, and overall process costs. With strong material compatibility, proven industry approvals, and compliance with RoHS, WEEE, and REACH, it offers a safe, sustainable, and cost-efficient cleaning solution.


2. Applications

  • Removal of baked-on fluxes from solder pallets, condensation traps, and solder ovens.

  • Cleaning SMT stencils, including unsoldered solder pastes.

  • Maintenance cleaning of conveyor fingers and other production tools.

  • Compatible with air-assisted, ultrasonic, and spray-in-air cleaning equipment.

  • Suitable for electronics manufacturers requiring extended bath life and lower disposal volumes.
