Abstract
Abstract A device is disclosed for attaching to or removing modular electronic components from a substrate which is adjustably positioned beneath a heater means delivering a flow of uniformly heated air. The heated air is directed to the sides of the component to melt solder associated with terminals thereon by a series of changable nozzles which can be moved into or out of registry with the component. Vacuum means is also provided for contacting the component to position it on or remove it from the substrate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
144 words
A device for attaching modular electronic components to or removing them from a substrate, said device comprising: (a) a frame having a support shaft secured at one end to said frame, (b) heater means slidably mounted on said support shaft intermediate the ends thereof for heating a flow of air from a source, said heater means having a first nozzle means secured to one end thereof for directing said heated air flow, (c) means for adjustably positioning said substrate containing said modular electronic component beneath said heater means, and (d) holder means slidably mounted on the other end of said shaft, said holder means having a second nozzle means removably mounted thereon which is adapted to substantially enclose said modular electronic component and direct said heated air flow from said first nozzle means adjacent the sides of said component to melt solder associated therewith.
Claim 2
Independent Claim
144 words
A device for attaching modular electronic components to or removing them from a substrate, said device comprising: (a) a frame having a support shaft secured at one end to said frame, (b) heater means slidably mounted on said support shaft intermediate the ends thereof for heating a flow of air from a source, said heater means having a first nozzle means secured to one end thereof for directing said heated air flow, (c) means for adjustably positioning said substrate containing said modular electronic component beneath said heater means, and (d) holder means slidably mounted on the other end of said shaft, said holder means having a second nozzle means removably mounted thereon which is adapted to substantially enclose said modular electronic component and direct said heated air flow from said first nozzle means adjacent the sides of said component to melt solder associated therewith.
Claim 3
Dependent Claim
29 words
The device as set forth in claim 1 further comprising vacuum means mounted for reciprocal movement within said heater means for contacting said modular electronic component and removing same.
Claim 4
Dependent Claim
34 words
The device as set forth in claim 1 wherein said heater means comprises a substantially cylindrical shaped heater element and said air from said source flows around said heater element and is heated thereby.
Claim 5
Dependent Claim
37 words
The device as set forth in claim 1 wherein said first nozzle means comprises plate means having a plurality of side-by-side nozzle openings formed therethrough which direct said heated air flow downward into said second nozzle means.
Claim 6
Dependent Claim
49 words
The device as set forth in claim 1 wherein said second nozzle means comprises an enclosure having side walls which taper from an upper opening adapted to receive said heated air flow to a lower opening whose shape is slightly larger than the periphery of said modular electronic component.
Claim 7
Dependent Claim
61 words
The device as set forth in claim 1 wherein said device further comprises shield means mounted on said frame above said substrate and said heater means can be moved from a position above said second nozzle means to a position above said shield means to thereby prevent said heated air from reaching said substrate during placement of said second nozzle means.
Claim 8
Dependent Claim
35 words
The device as set forth in claim 1 further comprising guide means adapted to be positioned on said holder means to facilitate the alignment of said modular electronic component directly beneath said second nozzle means.
Claim 9
Dependent Claim
53 words
The device as set forth in claim 1 wherein said means for adjustably positioning said substrate comprises: (a) rod means slidably mounted in said frame, said rod means having bracket means on the ends thereof for supporting said substrate therebetween, at least one of said bracket means being adjustable on said rod means.
Claim 10
Independent Claim
186 words
A device for attaching modular electronic components to or removing them from a substrate where each said component has a plurality of terminals extending from the periphery thereof, said device comprising: heater means having at least one passage extending therethrough for heating a fluid flowing through said passage; first nozzle means disposed at one end of the heater means, said first nozzle means including a plate having a plurality of nozzle openings where the configuration of the plurality of openings generally corresponds to that of the plurality of terminals of the component and where the heated fluid from the heater means flows through the nozzle openings; and second nozzle means disposed adjacent said first nozzle means for directing the heated fluid flowing through the nozzle openings to the terminals of the component, said second nozzle means having side walls defining a lower opening positionable adjacent said electronic component, said lower opening being larger than the periphery of said electronic component, said second nozzle means being separated from said substrate by a gap whereby heated fluid flows out of said gap after it has melted said solder.
Claim 11
Independent Claim
186 words
A device for attaching modular electronic components to or removing them from a substrate where each said component has a plurality of terminals extending from the periphery thereof, said device comprising: heater means having at least one passage extending therethrough for heating a fluid flowing through said passage; first nozzle means disposed at one end of the heater means, said first nozzle means including a plate having a plurality of nozzle openings where the configuration of the plurality of openings generally corresponds to that of the plurality of terminals of the component and where the heated fluid from the heater means flows through the nozzle openings; and second nozzle means disposed adjacent said first nozzle means for directing the heated fluid flowing through the nozzle openings to the terminals of the component, said second nozzle means having side walls defining a lower opening positionable adjacent said electronic component, said lower opening being larger than the periphery of said electronic component, said second nozzle means being separated from said substrate by a gap whereby heated fluid flows out of said gap after it has melted said solder.
Claim 12
Dependent Claim
33 words
A device according to claim 9, wherein said second nozzle means includes an enclosure having side walls which taper inwardly from an upper opening disposed adjacent to said plate to said lower opening.
