Solderability assessment of galvanic coatings in electronics

Abstract

The problem of providing high-quality soldered joints during the assembly and installation of electronic products draws attention to the use of effective methods for controlling the solderabil-ity of electronic components and func-tional coatings of parts. The solderabil-ity of electroplated coatings used in electronics was studied by two meth-ods: evaluating the spreading of a dosed drop of solder and the wetting force by molten solder. The criteria for evaluating the solderability of coatings are systematized and refined.
