Abstract
A recirculating strip processing apparatus is described comprising a recirculating stripper chain, a recirculating tool chain, a recirculating carrier follower chain and a recirculating die chain in a removable cassette for continuous processing of integrated circuit packages and leadframes. The processes described include deflashing an integrated circuit package, removal of the dam bar from the leadframe and cutting and bending the leads of the individual integrated circuit packages. When repair or replacement is required, the cassette involved is simply removed from the apparatus and replaced by another cassette thereby minimizing "down time" of the apparatus.
Claims22
An apparatus for processing a strip of material comprising:
- a plurality of tool means interconnected in an endless chain, for shaping predetermined parts of said strip of material;
- a plurality of follower means interconnected in an endless chain, for forcing said tool means against said predetermined parts of said strip of material;
- a plurality of die means interconnected in an endless chain which cooperate with said tool means, for shaping said predetermined parts of said strip of material;
- a plurality of stripping means interconnected in an endless chain for stripping said strip of material from said tool means after said shaping of said strip of material by said tool and die means;
- means for transporting said strip of material between said stripping means and said die means;
- and
- means for moving said tool, said follower, said stripping and said die means in a recirculating fashion relative to said strip of material as said strip of material is being transported therebetween.
