A method of forming external terminals of a package is provided in which a package substrate may be fixed, an edge portion of the package substrate may be supported to prevent the edge portion of the package substrate from being upwardly bent, a mask having openings may be arranged on the package substrate, and the external terminals may be supplied to the package substrate through the openings of the mask. The supporting portion may downwardly press the edge portion of the package substrate so that the edge portion of the package substrate may not be upwardly bent. As a result, the external terminals on the package substrate may have a uniform thickness.
