The solution calorimetric method was used for the determination of the formation enthalpy of Al 2 Fe and Al 5 Fe 2 intermetallic phases. The phases were prepared in a very pure Ar atmosphere by melting the calculated amounts of Al and Fe in alumina c

PurposeThe purpose of this article is to establish why the wetting on PCBs with SnCu (HASL) and Snimm finishes in the presence of a flux is better than the wetting of those on a copper substrate. The practical aspect of the obtained results is the ma
