In addition, recently, Japanese Patent Laid-Open No. 62-24755.
As described in Japanese Patent No. 3 or the like, the burr 10a of the synthetic resin is removed by irradiation with a laser beam. According to this method of deburring with a laser beam, although problems such as deformation of the lead frame do not occur, as in the above case, it is extremely necessary to irradiate the laser beam around the mold portion 10 during the manufacturing process of the semiconductor component. Since an expensive laser beam transmitter must be installed, this also complicates the process and increases the size of the equipment, further increasing the cost.
