Title: Manufacture of lead frame for semiconductor device and manufacturing apparatus
Inventor: WATANABE NORINAGA
IPC: H01L23/50
Filed: 1993-12-13
Abstract: PURPOSE:To provide a method of manufacturing a lead frame having an odd number of unit patterns using a press die to form two unit patterns simultaneously. CONSTITUTION:A long-length mother material 10 is intermittently fed to sequentially press a pair of patterns consisting of two unit patterns with a press die 8. The pressed mother material 10 is alternately cut with cutting blades 12, 13 of a cutting apparatus 11. Eight unit patterns are pressed from the mother material 10 with four times of feeding to the press die 8. The cutting blade 12 cuts the center of the pattern pair located at the lower position with four times of feeding to form a lead frame having seven unit patterns. The cutting blade 13 cuts the end part of pattern pair located at the lower position after three times of feeding to form a lead frame having seven unit patterns. With repetition of such processings, many lead frames 1 can be formed. The cutting apparatus 11 selectively operates the cutting blades 12, 13 with up and down movements of a movable spacer.

Abstract: PURPOSE:To remarkably increase the process amount of a shredder for compression-molding processed pieces efficiently by providing a press member for guiding the processed pieces cast from a guide means to make contact with the outer peripheral surface of a screw means just after casting the processed pieces. CONSTITUTION:Noodles cut off finely in a cutter section are converged through a guide means 21 and introduced into an annular space 29 of a cylinder 23 from a lateral opening 24 of the cylinder 23. Further, the noodle introduced into the annular space 29 receives efficiently a rotary driving force of a screw 25, so that the noodle is pressed by an elastic force of a press spring 32 acting about the fulcrum of a support shaft 31 with a pressing force at an inclined angle approximating to the tangential direction to the peripheral surface of the screw 25. When the annular space 29 is filled with the noodle, the noodle is elastically space from the inner wall side of a housing opposed to the periphery surface of the screw 25, while the noodle can sufficiently receive the rotary driving force of the screw 25 irrespective of an amount of the noodle since the elastic force of the spring 32 presses the noodle toward the peripheral surface.
