Abstract
Abstract Apparatus for preparing the conductors projecting from a flatpack for soldering comprises an anvil supporting the conductors and a soldering wire transversely of the conductors, a reciprocable plunger mounted above the anvil for exerting a predetermined pressure against a soldering wire placed transversely over the conductors, and cooperating side walls of the plunger and the anvil forming a scissors for severing the soldering wire upon downward movement of the plunger.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
91 words
An apparatus for preparing one or more electrical leads for soldering, said apparatus comprising a first forming member adapted to support said leads along with a supply of solder material in contact with said leads, a second forming member normally disposed in spaced relation to said first forming member, and means to press said forming members together to form a bond between said solder material and said leads, one of said forming members having means for limiting the flattening of said solder material during the pressing together of said forming members.
Claim 2
Independent Claim
91 words
An apparatus for preparing one or more electrical leads for soldering, said apparatus comprising a first forming member adapted to support said leads along with a supply of solder material in contact with said leads, a second forming member normally disposed in spaced relation to said first forming member, and means to press said forming members together to form a bond between said solder material and said leads, one of said forming members having means for limiting the flattening of said solder material during the pressing together of said forming members.
Claim 3
Dependent Claim
63 words
The apparatus of claim 1 wherein said solder material is in the form of a strip, and wherein said means for limiting the flattening of said solder material is in the form of a recess formed in said one forming member and adapted to receive a portion of said strip, the cross-sectional area of said recess being less than that of said strip.
Claim 4
Dependent Claim
38 words
a plunger mounted above the flat upper surface of the anvil member and vertically reciprocable in relation thereto, b. the plunger having a lower flat surface facing the upper surface of the anvil member and substantially parAllel thereto;
Claim 5
Dependent Claim
38 words
a plunger mounted above the flat upper surface of the anvil member and vertically reciprocable in relation thereto, b. the plunger having a lower flat surface facing the upper surface of the anvil member and substantially parAllel thereto;
Claim 6
Dependent Claim
25 words
means for exerting a predetermined downward pressure on the plunger against a soldering wire or rod placed transversely over the conductors through said groove; and
Claim 7
Dependent Claim
25 words
means for exerting a predetermined downward pressure on the plunger against a soldering wire or rod placed transversely over the conductors through said groove; and
Claim 8
Dependent Claim
42 words
The apparatus of claim 1 wherein said solder material is in the form of a strip, and wherein said first forming member comprises means for positioning said strip so that it extends in a generally transverse direction with respect to said leads.
Claim 9
Dependent Claim
30 words
The apparatus of claim 3 wherein said means for positioning said strip is in the form of a recess-defining means disposed adjacent the support surface of said first forming member.
Claim 10
Dependent Claim
35 words
cooperating side walls of the plunger and of the anvil member ledge forming a scissors upon downward movement of the plunger for severing the soldering wire or rod placed over the conductors through the groove.
Claim 11
Dependent Claim
35 words
cooperating side walls of the plunger and of the anvil member ledge forming a scissors upon downward movement of the plunger for severing the soldering wire or rod placed over the conductors through the groove.
Claim 12
Dependent Claim
54 words
The apparatus of claim 4 wherein said solder material is in the form of a continuous strip connected to a source of solder material, a portion of said second forming member being adapted to cooperate with said recess-defining means for severing said strip from said source during said pressing together of said forming members.
Claim 13
Dependent Claim
48 words
The apparatus of claim 1 wherein said solder material is in the form of a continuous strip connected to a source of solder material, and further comprising cooperating means on said forming members for severing said strip from said source during said pressing together of said forming members.
Claim 14
Independent Claim
90 words
An apparatus for preparing one or more electrical leads for soldering, said apparatus comprising a first forming member adapted to support said leads along with a strip of solder material connected to a supply thereof, a second forming member normally disposed in spaced relation to said first forming member, means to press together said forming members to form a bond between said solder material and said leads, and cooperating means formed on said forming members for severing said strip from said supply during the pressing together of said forming members.
Claim 15
Independent Claim
90 words
An apparatus for preparing one or more electrical leads for soldering, said apparatus comprising a first forming member adapted to support said leads along with a strip of solder material connected to a supply thereof, a second forming member normally disposed in spaced relation to said first forming member, means to press together said forming members to form a bond between said solder material and said leads, and cooperating means formed on said forming members for severing said strip from said supply during the pressing together of said forming members.
Claim 16
Dependent Claim
33 words
The apparatus of claim 7 wherein said first forming member comprises means for positioning said strip of solder material so that it extends in a generally transverse direction with respect to said leads.
Claim 17
Independent Claim
24 words
An apparatus for preparing for soldering a plurality of spaced conductors projecting from an electronic micro-element in one direction and in one plane, comprising
Claim 18
Independent Claim
24 words
An apparatus for preparing for soldering a plurality of spaced conductors projecting from an electronic micro-element in one direction and in one plane, comprising
Claim 19
Dependent Claim
42 words
The apparatus of claim 9 wherein the lower surface of the plunger defines a shallow groove extending in said transverse direction in alignment with said groove, the depth of the groove being less than the diameter of the soldering wire or rod.
