Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A bonding apparatus, in which electrodes on pellets and leads on lead frames are individually bonded to each other by means of a wire bonder, characterized in that said apparatus comprises a lead-pressing means which has at least two pressing arms with a corresponding pressing section at the end wherein one of said at least two pressing sections presses against a portion of said lead that is away from a bonding point thereof, a lead-pressing head for each of said at least two pressing arms which drives said at least two pressing arms in X and Y directions and in a vertical direction, so that bonding is performed while said portion of said lead that is away from said bonding point thereof is pressed down by said pressing section.
Claim 2
Dependent Claim
129 words
A bonding apparatus, in which electrodes on pellets and leads on lead frames are individually bonded to each other by means of a wire bonder, characterized in that said apparatus comprises a lead-pressing means which has at least two pressing arms with a corresponding pressing section at the end wherein one of said at least two pressing sections presses against a portion of said lead that is away from a bonding point thereof, a lead-pressing head for each of said at least two pressing arms which drives said at least two pressing arms in X and Y directions and in a vertical direction, so that bonding is performed while said portion of said lead that is away from said bonding point thereof is pressed down by said pressing section.
Claim 3
Dependent Claim
90 words
A wire bonding method in which electrodes on pellets and leads on lead frames are individually bonded to each other during a bonding step using a wire bonder, said method comprising pressing down during said bonding step a portion of said lead that is away from a bonding point of said lead by one of at least two pressing arms with each having a corresponding pressing section, and driving said at least two pressing arms and corresponding pressing section individually in X and Y directions and in a vertical direction.
Claim 4
Dependent Claim
90 words
A wire bonding method in which electrodes on pellets and leads on lead frames are individually bonded to each other during a bonding step using a wire bonder, said method comprising pressing down during said bonding step a portion of said lead that is away from a bonding point of said lead by one of at least two pressing arms with each having a corresponding pressing section, and driving said at least two pressing arms and corresponding pressing section individually in X and Y directions and in a vertical direction.
