Abstract

A hot-dip plating apparatus for plating a thin molten solder film can control a film thickness of a molten solder on a base material evenly and in increments of a few μm and achieve a thin-film solder plating having a film thickness less than a conventional system. As shown in FIG., this apparatus comprises a solder bathof accommodating the molten solder; a second conveying sectionfor drawing up a strip memberfrom the solder bath; and a blower sectionfor blowing hot gas on the strip memberimmediately after being drawn up from the solder bath by a second conveying section; the hot gas having a predetermined flow volume and a predetermined temperature equal to or higher than a melting temperature of the molten solder. According to this configuration, the excess molten soldercan be trimmed from the strip membercorresponding to composition of the molten solder. Thus, the film thickness of the molten soldercoated on the strip membercan be controlled evenly and in increments of a few μm.
