Abstract
A leadframe manufacturing apparatus includes a laser beam generator, a laser beam path tube through which laser beams travel, a leadframe transferring unit which transfers leadframe material to be irradiated by the laser beams, a controller connected to the laser beam generator and the leadframe transferring unit, which controls the transfer and irradiation of the leadframe material, a laser mask having a predetermined pattern, placed between the laser beam generator and the leadframe transferring unit, and a laser beam absorbing unit for supporting the leadframe transferring unit. A leadframe may also be manufactured by coating a leadframe material with a photoresist film capable of blocking the laser beams, and then patterning the photoresist film.
