Abstract
Abstract A shank adapted to be connected to and heated by a soldering iron carries at least one comblike member of heat conductive material, including a row of tapered, pointed prongs which are insertable in a row of solder-plugged eyelet holes in a printed circuit board so as to melt the solder and open up the holes for subsequent installation of wire leads of an electrical component such as an integrated circuit module. The material of the comblike member, including its prongs, is such that solder does not readily adhere thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A soldering iron tip for simultaneously opening a row of spaced solder-plugged eyelet holes in a printed circuit board comprising a shank adapted to be connected to and heated by a soldering iron, and a comblike member of heat-conductive material carried by said shank, said comblike member including a rigid back bar secured to the shank and a row of prongs provided integrally along one edge of said back bar, said prongs being spaced apart a distance corresponding to the spacing of said holes, and being formed of a material to which solder does not readily adhere, said prongs being further characterized in that they are longitudinally tapered and terminate in pointed extremities.
Claim 2
Dependent Claim
113 words
A soldering iron tip for simultaneously opening a row of spaced solder-plugged eyelet holes in a printed circuit board comprising a shank adapted to be connected to and heated by a soldering iron, and a comblike member of heat-conductive material carried by said shank, said comblike member including a rigid back bar secured to the shank and a row of prongs provided integrally along one edge of said back bar, said prongs being spaced apart a distance corresponding to the spacing of said holes, and being formed of a material to which solder does not readily adhere, said prongs being further characterized in that they are longitudinally tapered and terminate in pointed extremities.
Claim 3
Dependent Claim
30 words
The device as defined in claim 1 which is further characterized in that said prongs project from said back bar in a plane parallel to the axis of said shank.
Claim 4
Dependent Claim
49 words
The device as defined in claim 1 which also includes a second comblike member identical to the first mentioned comblike member and disposed in spaced parallel juxtaposition relative thereto, said shank including a bifurcated portion by the furcations of which the respective first and second comblike members are carried.
Claim 5
Dependent Claim
18 words
The device as defined in claim 1 wherein the material from which said prongs are formed is aluminum.
Claim 6
Dependent Claim
19 words
The device as defined in claim 1 wherein the material from which said prongs are formed is stainless steel.
