A method for determining a cause of a mounting failure of each of a plurality of components mounted on a substrate, the method being performed by an electronic device, may include the steps of: receiving a check result of whether the mounting of each of a plurality of first components is unqualified, the inspection result is determined by inspecting a plurality of first-type substrates on which a plurality of first components are mounted, and the mounting positions of the first-type substrates of the plurality of first components are different from one another; calculating a mounting disqualification rate of each of the plurality of first components by using the inspection result; based on the mounting disqualification rate of each of the plurality of first components, determining a plurality of second components with disqualified mounting in the plurality of first components; and based on the mounting disqualification rate of each of the plurality of first components, determining the cause of mounting disqua
