Abstract

PURPOSE:To remove a resin burr simply without requiring large-scaled facilities by grinding the resin burr by a rotary grindstone and removing the chips by a rotary brush. CONSTITUTION:A work is carried along carrying rails 21, 22 while turning rotary grindstones 25, 30 and rotary brushes 33, 33', and resin burrs adhering on the upper surface of the work are ground and removed by the rotary grindstone 25 when the work reaches to the position of the rotary grindstone 25. When the work is carried to the position of the rotary grindstone 30, resin burrs adhering on the lower surface of the work are shaved off. When the work is carried to the positions of the rotary brushes 33, 33', the chips of the resin burrs remaining on the work are removed by brushing by the rotary brushes 33, 33'. The quantities of grinding by the rotary grindstones 25, 30 are set to desired values by adjusting the height of the grindstones 25, 30 by adjusting screws 29. The resin burrs 12 remaining among the leads slip off and are removed on the bending and molding of the leads.

By the way, in the 1-transfer molding process for forming the resin mold layer 1, it is difficult to completely seal the molding area, so the resin leaking from the molding cavity may leak out from the outer lead 3. It adheres to the surface and generates so-called resin particles 6 as shown in FIG. This resin debris will cause the lead 3 to not be plated in the next plating process.
It must be removed after the resin molding process is completed. Conventionally used methods for this purpose include a liquid honing method, a dry honing method, and an electrolytic deburring method.

液体ホーニング法は、アルミナ等の研磨材と水との混合

The liquid honing method involves spraying a liquid mixture of water and an abrasive material such as alumina through a nozzle to remove attached resin particles.

The dry honing method also involves spraying an abrasive to remove resin particles, but this method differs in that the abrasive is directly sprayed without using water.

That is, in the liquid honing method and the dry honing method, it is necessary to use a protective mask to prevent the resin mold layer 1 from being damaged, and there are also problems in that it is difficult to adjust the amount of scraping. On the other hand, in the electrolytic deburring method, since the lead frame is immersed in an electrolytic solution such as NaOH, there is a problem in that the material of the lead frame must be limited.
