Abstract
A method for classifying solder particles includes: a first step of forming an electric field between a first electrodeand a second electrodeincluded in an electrostatic attraction device, the first electrodehaving a disposition part having electrostatic diffusivity or electrical conductivity, the second electrodehaving an attraction parthaving electrical insulation properties, which faces the disposition part and is provided with a plurality of opening partsopened to the disposition part side, so as to cause solder particles P disposed on the disposition part to be electrostatically attracted to the attraction part; a second step of removing solder particles Pattracted to areas other than the opening partsof the attraction part; and a third step of collecting solder particles Paccommodated in the opening parts, from the attraction partthat has been subjected to the second step.
