Abstract
Abstract A solder delivery system has a continuous element of solder material adjacent to at least one polymeric layer, which is provided with window means to control the flow of solder. The layers, if there are more than one, may be separate pieces, or may be parts of a folded sheet or a tube of polymeric material. In use, the conductors to be soldered are placed adjacent to corresponding terminals of a substrate and the system placed in contact with and perpendicular to the conductors, with the window means towards the conductors. On the application of heat and pressure, the solder melts and flows toward the terminals, and solder bridges are prevented by the "window frames" which lie between the terminals.

Claim 1
Independent Claim
63 words
A solder delivery system comprising: (a) at least one layer of polymeric material having window means therethrough; and (b) a solder strip with flux disposed in operative contact with said at least one layer and adjacent said window means; said window means directing the flow of solder and flux from said solder strip through said window means when said delivery system is heated.
Claim 2
Dependent Claim
63 words
A solder delivery system comprising: (a) at least one layer of polymeric material having window means therethrough; and (b) a solder strip with flux disposed in operative contact with said at least one layer and adjacent said window means; said window means directing the flow of solder and flux from said solder strip through said window means when said delivery system is heated.
Claim 3
Dependent Claim
16 words
A solder delivery system as in claim 1 which comprises a single layer of polymeric material.
Claim 4
Dependent Claim
23 words
A solder delivery system as in claim 1 wherein said window means are further adapted to grip conductors placed in operative contact therewith.
Claim 5
Dependent Claim
55 words
A method of aligning the stripped conductors of a cable to be soldered using the solder delivery system of claim 3 which comprises: (a) aligning said cable with said system; and (b) burnishing said conductors into the window means of said system so that the conductors are gripped by said window means and thereby aligned.
Claim 6
Dependent Claim
45 words
A solder delivery system as in claim 1 further comprising a backing layer having a perforation aligned with each of said window means to allow an end of a conductor entering said window means to exit through said backing layer by passing through said perforation.
Claim 7
Dependent Claim
55 words
A method of aligning the stripped conductors of a cable to be soldered using the solder delivery system of claim 4 which comprises: (a) aligning said cable with said system; (b) combing the conductors; and (c) inserting the ends of the conductors through said window means and then through said perforation in said backing layer.
Claim 8
Dependent Claim
88 words
A solder delivery system comprising: (a) at least one layer of polymeric material having window means therethrough; and (b) a solder strip with flux disposed in operative contact with said at least one layer and adjacent said window means; said window means directing the flow of solder and flux from said solder strip through said window means when said delivery system is heated, and electrical conductor means permitting the formation of a soldered electrical interconnection between conductive substrates placed on either side of said at least one layer.
Claim 9
Dependent Claim
88 words
A solder delivery system comprising: (a) at least one layer of polymeric material having window means therethrough; and (b) a solder strip with flux disposed in operative contact with said at least one layer and adjacent said window means; said window means directing the flow of solder and flux from said solder strip through said window means when said delivery system is heated, and electrical conductor means permitting the formation of a soldered electrical interconnection between conductive substrates placed on either side of said at least one layer.
Claim 10
Dependent Claim
22 words
A solder delivery system as in claims 1 or 5 wherein said at least one layer having window means has adhesive character.
Claim 11
Dependent Claim
19 words
A solder delivery system as in claim 6 wherein said at least one layer is coated with an adhesive.
Claim 12
Dependent Claim
17 words
A solder delivery system as in claim 6 wherein said at least one layer is intrinsically adhesive.
Claim 13
Dependent Claim
73 words
An electrical connector cable which comprises: (a) at least one layer of polymeric material having at least two rows of window means therethrough; (b) a solder strip for each row of window means disposed in operative contact with said at least one layer and adjacent said each row of window means; and (c) electrical conductors disposed in operative contact with said at least one layer and running between said rows of window means.
Claim 14
Dependent Claim
73 words
An electrical connector cable which comprises: (a) at least one layer of polymeric material having at least two rows of window means therethrough; (b) a solder strip for each row of window means disposed in operative contact with said at least one layer and adjacent said each row of window means; and (c) electrical conductors disposed in operative contact with said at least one layer and running between said rows of window means.
Claim 15
Dependent Claim
46 words
A method of aligning the stripped conductors of a cable to be soldered using the solder delivery system of claim 1 which comprises: (a) aligning said cable with said system; and (b) burnishing said conductors into the window means of said system, thereby causing their alignment.
