Influence of the doping additives on heat stability and heat transfer of nickel coverings of cases IC

With the help of modern diagnostic microanalysis tools, the regularities are established for variation of electrophysical parameters of Ni-B galvanic coating of IC packages in the process of ultrasonic welding of internal Al leads and package seal. The optimal composition of the electrolyte which pr...
