Solvent-based medium for PCB flux removal

ZESTRON® FA+ is a 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). It is surfactant-free, easily rinsed and does not require explosion-proof precautions.

Advantages compared to other surfactant cleaners:

  • High bath loading capability results in long bath life
  • Does not require any specific explosion-proof environment
  • Due to the surfactant-free formulation, it is easily rinsed
  • Increases wire bonding/molding quality for power modules, leadframe-based discrete components and Power LEDs
  • Ensures a void-free underfill and improves the image resolution by removing all tacky fluxes from Flip Chips/CMOS
  • Has been EMPF Phase II tested and MIL approved
  • Listed on the ESA ‘list of declared materials’


Area of Specific Application



  • Flux residues
  • Solder paste (unsoldered)
  • SMT or conductive adhesives
