A Study on the Solderability of Pure Nickel with Different Tin-Lead Solders using Resin and Zinc Ammonium Chloride Fluxes

Nickel and its alloys can be successfully soldered using tin-lead solders. For several engineering and electronic applications, either nickel and its alloys or other metallic materials coated with nickel are to be soldered. Even though the soldering practice for nickel has been in use for some years, data concerning systematic fundamental studies on the solderability of nickel with different solders and fluxes under different conditions of soldering are scarce in literature. In this work, an attempt has been made to study the effect of solder composition, nature of flux and soldering temperature on the efficiency of soldering and on the joint strength of butt and lap soldered joints of pure nickel.
