An apparatus for presoldering electrical components can include a die device having a punch member for punching a solder preform from a sheet of solder, and pressing the solder preform against an electrical component. A heating device can press against the electrical component on a opposite side from the die device for sandwiching the electrical component between the punch member and the heating member, for heating the electrical component and melting the solder preform thereon.
