Solvent for defluxing in semi-aqueous processes

Solvent-based cleaning agent designed to remove all types of flux residues from electronic assemblies, ceramic hybrids, power electronics (power modules, leadframe-based discrete components, power LEDs) and packages (Flip Chips(CMOS). The product is characterized by its high cleaning performance and bath loading capability ensuring an extremely long bath life.

Advantages compared to other cleaners:

  • High bath loading capability of ZESTRON® FA+ ensures extended bath life.
  • The cleaning medium does not require any specific explosion-proof environment.
  • Due to the surfactant-free formulation, ZESTRON® FA+ can be easily rinsed.
  • This cleaning medium is listed in the ESA “list of declared materials

Area of Specific Application:

  • PCB and advance packaging
  • Solvent-based Technology


  • Ultrasonic
  • Spray-under-immersion
  • Centrifugal cleaning


  • Flux residues
  • Solder paste (unsoldered)
