ABSTRACT:
A method and apparatus for manufacturing preform panels having at least one preform for repairing interconnects, particularly for repairing meander-like interconnects with a preform plated with hard solder. The metal has at least the steps of: providing at least two successive punch events with a die; and performing a predetermined feed (V) between a metal band and the die between the two punch events, whereby the length of the feed (V) is greater than a die width of the die, a length of the die being shorter than a width of the metal band, and the preform being formed by a residual web of the metal band after the two successive punch events. The apparatus for manufacturing preform panels having at least one preform from a metal band has at best: a receptacle plate on a carriage for the acceptance of the metal band; a die with a means for hold-down; a motor for generating a predetermined feed between the die and the metal band; at least two positioning pins for positioning the metal band on the receptacle plate; and a die-plate that cooperates with the die that is perpendicularly movable up and down and with its hold-down means.
