1. Product Overview
VIGON® EFM is a precision cleaning medium formulated from halogen-free organic solvents, specifically designed for manual flux removal in electronic assemblies. It is fast-drying, residue-free, non-corrosive, and highly compatible with most polymers. Extensively tested for both leaded and lead-free solder pastes and liquid fluxes, it offers reliable cleaning performance in delicate manual applications. Fully compliant with RoHS and REACH, the product is biodegradable, making it both safe and environmentally responsible.


2. Applications

  • Manual cleaning of printed circuit boards (PCBs).

  • Effective removal of flux residues from No-Clean (NC), Rosin Mildly Activated (RMA), Rosin (R), and Rosin Activated (RA) solder pastes.

  • Suitable for leaded and lead-free solder pastes and liquid fluxes.

  • Functions as both a cleaning and rinsing agent.

  • Available for use in both liquid and aerosol form, including manual cleaning with brush or aerosol spray.
