Composés de résine, de solvant, et d'une petite quantité d'activateur, la plupart des flux RMA sont assez faiblement actifs et conviennent mieux aux surfaces facilement soudables. Le résidu de flux RMA est clair, mou, non-corrosif et non-conducteur. Le nettoyage est facultatif. Le résidu peut être éliminé avec un solvant approprié. LOCTITE® 6381-35 provides the following product characteristics: Technology Liquid flux Application Wave soldering LOCTITE® 6381-35 liquid flux is a mildly activated rosin (RMA) flux with a proprietary formulation that combines superior mobility and spread with faster initial and sustained wetting action. It is more effective and will maintain operating activity longer than conventional RMA type fluxes. FEATURES AND BENEFITS ? Rosin based ? Fast soldering throughput, fewer defects and rework ? Residues easily removed where required ? Solders difficult surfaces ? Ideal for multilayer, PTH and SMD applications ? Heat stable ? Halide activated APPLICATIONS LOCTITE® 6381-35 can be reliably and cost-effectively used where the solderability of an assembly needs an active flux formulation approaching an RA type but specifications mandate an RMA flux. It is ideal for use with multilayer, surface mount, densely populated and complex boards. Solder spread is up to 50% greater than conventional RMA fluxes ensuring excellent penetration of plated through holes.
