ABSTRACT:
In a soldering process for joining a plurality of metal components wherein a flux is employed to promote the process, the improvement comprises using as a flux in the process a flux consisting essentially of dihydroabietyl alcohol or dihydroabietyl alcohol and a member selected from the group consisting of a thermally depolymerizable polymer or a mixture of thermally depolymerizable polymers having the structure: ##STR1## where X and Y are n-alkyl and iso-alkyl not exceeding 6 carbon atoms; halogen; --COOR where R is n-alkyl and iso-alkyl not exceeding 6 carbon atoms; phenyl, naphthyl, tolyl and methyl-naphthyl groups; n is 5 to 500, and mixtures thereof.
