Abstract
Abstract A component lead tip protruding from a hole of a circuit board is split and displaced in order to attach the component to the circuit board. Trimming of the lead to a preferred length generally simultaneously with the splitting is also possible.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
82 words
In a method of attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising the steps of: splitting at least a portion of said protruding lead generally longitudinally to provide furcations; and displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching.
Claim 2
Dependent Claim
82 words
In a method of attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising the steps of: splitting at least a portion of said protruding lead generally longitudinally to provide furcations; and displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching.
Claim 3
Dependent Claim
20 words
An improvement as in claim 1, and further comprising the step of: trimming said protruding lead to a preferred length.
Claim 4
Dependent Claim
19 words
An improvement as in claim 2, and further comprising the step of: performing said trimming prior to said splitting.
Claim 5
Dependent Claim
18 words
An improvement as in claim 2, and further comprising the step of: performing said trimming after said splitting.
Claim 6
Dependent Claim
20 words
An improvement as in claim 2, and further comprising the step of: performing said trimming generally simultaneously with said splitting.
Claim 7
Dependent Claim
104 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottom side of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in oder to effect said attaching; means for trimming said protruding lead to a preferred length; and means for performing said trimming generally simultaneously with said splitting.
Claim 8
Dependent Claim
104 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottom side of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in oder to effect said attaching; means for trimming said protruding lead to a preferred length; and means for performing said trimming generally simultaneously with said splitting.
Claim 9
Dependent Claim
111 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching; means for trimming said protruding lead to a preferred length, said trimming means comprising a die means for cooperating with said splitting means in order to perform said trimming.
Claim 10
Dependent Claim
111 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching; means for trimming said protruding lead to a preferred length, said trimming means comprising a die means for cooperating with said splitting means in order to perform said trimming.
Claim 11
Dependent Claim
157 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations and comprising at least two tools having means for receiving said protruding lead therebetween, said tools being moveable relative to each other and cooperative in a shearing action to effect said splitting; means for moving said tools relative to each other for said shearing action; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching; and means for trimming said protruding lead to a preferred length, said trimming means comprising a die means for cooperating with said splitting means in order to perform said trimming.
Claim 12
Dependent Claim
157 words
In an apparatus for attaching a component to a substrate by deforming at least one lead protruding from a bottomside of said substrate, said lead extending from a topside and through a hole of said substrate to said bottomside, the improvement comprising: means for splitting at least a portion of said protruding lead generally longitudinally to provide furcations and comprising at least two tools having means for receiving said protruding lead therebetween, said tools being moveable relative to each other and cooperative in a shearing action to effect said splitting; means for moving said tools relative to each other for said shearing action; means for displacing at least one of said furcations laterally of a longitudinal axis of said protruding lead in order to effect said attaching; and means for trimming said protruding lead to a preferred length, said trimming means comprising a die means for cooperating with said splitting means in order to perform said trimming.
Claim 13
Dependent Claim
50 words
An improvement as in claim 8, and further comprising: said die means having an outer surface with an orifice therein for receiving a portion to be trimmed from said protruding lead; and said tools being relatively slideable across said outer surface at said orifice in order to effect said trimming.
