Cleaning solder paste residues and all types of solder fluxes


TOPKLEAN™ EL 20R was developed by Inventec and is the booster version of TOPKLEAN™ EL 20A useful for cleaning solder paste residues and all types of solder flux and for cleaning poorly screen-printed boards.

Like TOPKLEAN™ EL 20A, this product can also be used as a co-solvent together with PROMOSOLV™ DR1 or the new PFAS-free solvent PROMOSOLV™ NEO A1.

TOPKLEAN™ EL 20R is a specially formulated cleaner to remove all types of flux residues and contaminants (fingerprints, dust, etc.) left on printed circuit board assemblies or semiconductor modules. Its chemical and physical characteristics enable it to effectively remove lead-free solder pastes and fluxes on the market and clean hard-to-reach areas.
