Abstract:
A method of attaching portions of adhesive tape to a plurality of LOC leadframes, said method comprising:providing a first source of a first adhesively coated material;providing a second source of a second adhesively coated material;providing a plurality of LOC leadframes in leadframe-by-leadframe sequence, each leadframe of said plurality of leadframes having a site for the attachment of a semiconductor die;providing indexing apparatus to supply said plurality of LOC leadframes in leadframe-by-leadframe sequence, each leadframe of said plurality of LOC leadframes having a first location at said site for a semiconductor die for receiving a first portion of said first adhesively coated material and a second location at said site for a semiconductor die for receiving a second portion of said second adhesively coated material;providing application apparatus configured to receive said first adhesively coated material at the first location of the site for a semiconductor die, to receive said second adhesively coated material at the second location of the site for a semiconductor die, and to receive said plurality of LOC leadframes in leadframe-by-leadframe sequence, said application apparatus including cutting apparatus for cutting and applying a first portion of said first adhesively coated material to the first location of the site for a semiconductor die and for cutting and applying a second portion of said second adhesively coated material to the second location of the site for a semiconductor die;operating said first source to supply a length of said first adhesively coated material to said application apparatus;operating said second source to supply a length of said second adhesively coated material to said application apparatus;operating said application apparatus to cut said first portion from said length of said first source of adhesively coated material and to apply said first portion to the first location at the site for a semiconductor die of each leadframe of said plurality of LOC leadframes; andoperating said application apparatus to cut said second portion from said length of said second adhesively coated material and to apply said second portion of said length of second adhesively coated material to the second location of the site for a semiconductor die of each of said LOC leadframes of said plurality of leadframes at the second location.
