Abstract

PURPOSE:To eliminate the variation of leads and the floating of hanging leads above the upper surface of a die in a semicoductor manufacturing apparatus used to isolate a semiconductor device from a lead frame by providing a protruding member which is operated independently from a punch and a pressing plate on a die set. CONSTITUTION:When the die set 13 of a semiconductor manufacturing apparatus 11 is operated in the direction of an arrow (y) to reach the vicinity of a bottom dead point, a punch 18 and a pressing plate 20 are respectively approximately simultaneously contacted with leads 5 and a semiconductor element placing unit 8. At this time, a protruding member 34 is contained in through holes 33, 19a, 20b. While a die set 12 is further operated to reach a bottom dead point, the punch 18 and the plate 20 respectively cut the leads 5 and hanging leads 2. On the other hand, the member 34 is protruded from the end 20a of the plate 20 at the same time of slightly delayed upon cutting, i.e., by the operation of an air cylinder 31 at the end at the bottom dead point of the die set 13, thereby dropping downwardly a semiconductor device 7.

As explained above, according to the present invention, the die set is provided with a punch and a push plate for cutting the lead part, and the die set is also provided with a protruding part that operates independently of the punch and the push plate. The semiconductor device can be ejected by the ejecting member substantially simultaneously with the cutting. Therefore, unlike in the past, only the suspension lead is cut first and the lead is not bent from the tip end, so there is no need to manually correct the bent lead, and work efficiency can be improved. In addition, since only one side of the suspension lead is cut and the suspension lead on the other side and the lead 7 frame are connected to each other and do not float to the top of the die, this may adversely affect the next processing. This eliminates the possibility of damage to the punch and die, resulting in improved productivity.
