22500MCS 60/40 500G 0.71MM SOLDER 60% TIN, 40% WHILE STOCK LAST LOCTITE MC084Ersin 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. Approx Metres per KG: 1.
