Ersin Multicore is solder in the form of a continuous wire with 5 cores of extra-active, non-corrosive Ersin flux running throughout its length. This increases its fluxing action.
Ersin flux not only removes surface oxides, but prevents them reforming during soldering. The thinner diameters of 0.71mm and 0.355mm are especially useful in the soldering of miniature components and the interconnection of integrated circuits.
