Abstract
Abstract A solder removing device is disclosed including fibres of temperature-resistant non-metallic material, such as a synthetic polymeric material, for example FEP or PTFE, which are coated with a metal rendering them more receptive to solder flux. The metallized fibres are coated with solder flux rendering them more capable of wetting with molten solder, interstices between the fibres serving to absorb molten solder by capillary attraction.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
66 words
A solder removing device, comprising (a) a group of fibers (30) formed from a temperature-resistant non-metallic material; (b) at least one layer of metal (32) metallizing said fibers; and (c) a layer of solder flux (34) coating the metallized fibers, thereby to render the fibers more capable of wetting with molten solder, whereby the interstices between the fibers serve to absorb molten solder by capillary attraction.
Claim 2
Dependent Claim
66 words
A solder removing device, comprising (a) a group of fibers (30) formed from a temperature-resistant non-metallic material; (b) at least one layer of metal (32) metallizing said fibers; and (c) a layer of solder flux (34) coating the metallized fibers, thereby to render the fibers more capable of wetting with molten solder, whereby the interstices between the fibers serve to absorb molten solder by capillary attraction.
Claim 3
Dependent Claim
11 words
A device in claim 1, in which the flux is rosin.
Claim 4
Dependent Claim
17 words
A device is claimed in claim 1, in which the non-metallic material is a synthetic polymeric material.
Claim 5
Dependent Claim
17 words
A device as claimed in claim 3, in which the synthetic polymeric material is a fluoroethylene polymer.
Claim 6
Dependent Claim
16 words
A device as claimed in claim 3, in which the synthetic polymeric material is a polytetrefluoroethylene.
Claim 7
Dependent Claim
15 words
A device as claimed in claim 1, in which the non-metallic material is glass fibre.
Claim 8
Dependent Claim
19 words
A device as claimed in claim 1, in which the group of fibres are disposed together in non-woven form.
Claim 9
Dependent Claim
17 words
A device as claimed in claim 7, in which the fibres are adhered together by the flux.
Claim 10
Dependent Claim
17 words
A device as claimed in claim 1, in which the fibres are woven, braided or stranded together.
Claim 11
Dependent Claim
17 words
A device as claimed in claim 1, wherein said device is in the form of a pad.
Claim 12
Independent Claim
60 words
A method of forming a solder removing device, which comprises the steps of (a) grouping together a plurality of fibers formed from a temperature-resistant non-metallic material; (b) coating the fibers with at least one layer of metal, thereby to metallize the fibers and render them more receptive to solder flux; and (c) coating the metallized fibers with solder flux (34).
Claim 13
Independent Claim
60 words
A method of forming a solder removing device, which comprises the steps of (a) grouping together a plurality of fibers formed from a temperature-resistant non-metallic material; (b) coating the fibers with at least one layer of metal, thereby to metallize the fibers and render them more receptive to solder flux; and (c) coating the metallized fibers with solder flux (34).
Claim 14
Dependent Claim
34 words
A method as defined in claim 11, wherein the fiber coating step precedes the grouping step; and (d) further including the step of coating the metallized fiber group with a second metal layer (32).
