Multiflux EO-B-023E is universally suitable for rework, hand and selective soldering as well as cable assembly. Accordingly, it contains organic, halogen-free activating additives with resin in a combination specially tuned to the thermal requirements of the soldering processes. EO-B-023E can be applied by brushing, spraying, dipping etc. The solids content is 15 wt.-%. EO-B-023E is totally free from corrosion action.
Additional information on the ingredients (hazardous substances), safe handling, storage, transport and disposal can be found in the current safety data sheet (SDS, SDS, MSDS).
This flux is very versatile and OSP-compatible. Good results are achieved in wave, selective and manual soldering as well as in cable assembly/strand tinning. The generally applicable rule of choosing flux quantities that are as low as possible also applies to this product.
