Abstract
An apparatus for processing semiconductor lead frames is described which comprises a plurality of stations arranged in a substantially circular path for processing the lead frames. The apparatus further includes processing means located at each station for processing the lead frames and transferring means for transferring the lead frames between stations for processing. The processing means includes a removable die module for housing tool kits which work the lead frames and which can be replaced to process different types of lead frames or to produce a different product from the lead frames.
Claims18
An apparatus for processing semiconductor lead frame comprising:
- (a) a plurality of stations arranged in a substantially circular path for processing said lead frames;
- (b) processing means located at each end of said stations for processing a lead frame, said processing means including a die module removably secured to said stations, said die module comprising a frame defining a plurality of cavities for holding a plurality of tool kits for working on said lead frames;
- and
- (c) transferring means for transferring said lead frames between said stations.
An apparatus as in claim I wherein each of said processing means at said stations includes means for performing any one of the following tasks:
- deflashing, dambaring, trimming, forming, marking, stamping, checking, singulating, lead conditioning, assembling, and packaging of said lead frames.
An apparatus for processing semiconductor lead frames comprising:
- (a) a plurality of stations arranged in a substantially circular path for processing said lead frames;
- (b) processing means located at said stations for processing said lead frames, said processing means including a die module removably secured to said stations, said die module comprising a frame defining a plurality of cavities for holding a plurality of tool kits for working on the lead frames;
- and
- (c) transferring means for transferring said lead frames between said stations, said transferring means comprising a rotatable mechanism positioned at a point substantially close to the center of said circular path, said mechanism having a plurality of wing arms for rotating said lead frames between said stations, and means for removing said lead frames from said stations and for positioning said lead frames at said stations, said removing and positioning means including means for raising and lowering said lead frames.
