Abstract:
An apparatus for manufacturing a leadframe, said leadframe with components of a chip pad, an inner lead and an external lead, comprising:a laser beam generator generating a laser beam and projecting the laser beam on a laser beam path from the laser beam generator to a leadframe, the laser beam irradiating over an area of the chip pad, the inner lead and the external lead to form a component of the leadframe;a laser beam path tube that substantially covers the laser beam path;a leadframe transferring unit that transfers leadframe material to be irradiated by said laser beam generator;a controller connected to said laser beam generator and said leadframe transferring unit, which controls the transfer and irradiation of said leadframe material;a laser mask located between said laser beam generator and said leadframe transferring unit, said laser mask containing a pattern corresponding to the leadframe; anda laser beam absorbing unit, for supporting said leadframe transferring unit.
