Abstract

An electroplating apparatus includes a plurality of feeding rollers adapted to advance a sheet-shaped article, and a spraying unit. The spraying unit has a pair of upper and lower casings, each of which includes a casing body defining a chamber, and a net plate disposed to confront with the article. An electrolyte is sprayed from the chamber via meshes in the net plate and onto a side surface of the article. An anode current-conducting assembly includes a conducting net that is disposed fixedly within the chamber and that is superimposed on the net plate so as to cover the meshes in the net plate, and two conducting units respectively in electrical contact with two opposite side portions of the conducting net so as to supply electric current to the conducting net.
