Abstract:
A method of manufacturing an electronic component having a construction in which surface-mounting components are accommodated inside a shielding case, the method comprising the steps of:preparing a mother printed-circuit board on which a plurality of surface-mounting components are to be mounted, the mother printed-circuit board provided with component-connecting electrodes to which external electrodes of the surface-mounting components are to be connected, engagement holes into which engagement protrusion portions of a shielding case are to be inserted, and case-fixing electrodes provided inside the engagement holes and on the mother printed-circuit board; mounting a plurality of surface-mounting components on the mother printed-circuit board and connecting external electrodes of the surface-mounting components to the component-connecting electrodes of the mother printed-circuit board; applying soldering paste such that soldering paste is not entirely filled inside the engagement hole and is provided on at least a portion of the case-fixing electrodes provided on the mother printed-circuit board; engaging a plurality of shielding cases with the mother printed-circuit board such that the engagement protrusion portions of the shielding case are inserted into the engagement holes of the mother printed-circuit board; soldering the engagement protrusion portions of the shielding cases to the case-fixing electrodes inside the engagement holes by melting the soldering paste; and cutting the mother printed-circuit board into areas on each of which a shielding case is mounted and dividing the mother printed-circuit board into a plurality of individual electronic components in each of which surface-mounting components are accommodated inside a shielding case; wherein the engagement protrusion portions of the shielding cases are inserted into the engagement holes of the mother printed-circuit board from a aide of the mother printed-circuit board on which the soldering paste is applied.
